    Summary:Sun/sky photometry and polarimetry of atmospheric light have been undertaken by multispectral photometers and a polarimeter over Amami, Noto, and Shirahama, Japan, during APEX-E1, -E2, and ACE-Asia field campaigns. Radiometers provide us with the optical thickness of aerosols and Angstrom exponent. Other aerosol characteristics, e.g., size distribution, refractive index, etc., are retrieved based on each inversion method corresponding each equipment. The former takes a standard AERONET processing, and the latter is according to our own procedure to analyze the polarimetry with PSR-1000. After several aerosol parameters are derived, the HYSPLIT4 backward trajectory analysis is adopted to search the origin of aerosols. It is shown from these ground measurements that aerosol optical thickness, Angstrom exponent, and refractive index are classified into two typical categories as a background type detected in winter, and a soil dust type appeared in Asian dust events in spring.

  • Depolarization ratios retrieved by AERONET sun-sky radiometer data and comparison to depolarization ratios measured with lidar, Youngmin Noh, Detlef Muller, Kyunghwa Lee, Kwanchul Kim, Kwonho Lee, Atsushi Shimizu, Sang-Woo Kim, Itaru Sano, Chan Bong Park, ATMOSPHERIC CHEMISTRY AND PHYSICS, ATMOSPHERIC CHEMISTRY AND PHYSICS, 17(10), 6271 - 6290, May 2017 , Refereed
    Summary:The linear particle depolarization ratios at 440, 675, 870, and 1020 nm were derived using data taken with the AERONET sun-sky radiometer at Seoul (37.45 degrees N, 126.95 degrees E), Kongju (36.47 degrees N, 127.14 degrees E), Gosan (33.29 degrees N, 126.16 degrees E), and Osaka (34.65 degrees N, 135.59 degrees E). The results are compared to the linear particle depolarization ratio measured by lidar at 532 nm. The correlation coefficient R-2 between the linear particle depolarization ratio derived by AERONET data at 1020 nm and the linear particle depolarization ratio measured with lidar at 532 nm is 0.90, 0.92, 0.79, and 0.89 at Seoul, Kongju, Gosan, and Osaka, respectively. The correlation coefficients between the lidar-measured depolarization ratio at 532 nm and that retrieved by AERONET at 870 nm are 0.89, 0.92, 0.76, and 0.88 at Seoul, Kongju, Gosan, and Osaka, respectively. The correlation coefficients for the data taken at 675 nm are lower than the correlation coefficients at 870 and 1020 nm, respectively. Values are 0.81, 0.90, 0.64, and 0.81 at Seoul, Kongju, Gosan, and Osaka, respectively. The lowest correlation values are found for the AERONET-derived linear particle depolarization ratio at 440 nm, i.e., 0.38, 0.62, 0.26, and 0.28 at Seoul, Kongju, Gosan, and Osaka, respectively. We should expect a higher correlation between lidar-measured linear particle depolarization ratios at 532 nm and the ones derived from AERONET at 675 and 440 nm as the lidar wavelength is between the two AERONET wavelengths. We cannot currently explain why we find better correlation between lidar and AERONET linear particle depolarization ratios for the case that the AERONET wavelengths (675, 870, and 1020 nm) are significantly larger than the lidar measurement wavelength (532 nm). The linear particle depolarization ratio can be used as a parameter to obtain insight into the variation of optical and microphysical properties of dust when it is mixed with anthropogenic pollution particles. The single-scattering albedo increases with increasing measurement wavelength for low linear particle depolarization ratios, which indicates a high share of fine-mode anthropogenic pollution. In contrast, single-scattering albedo increases with increasing wavelength for high linear particle depolarization ratios, which indicated a high share of coarse-mode mineral dust particles. The retrieved volume particle size distributions are dominated by the fine-mode fraction if linear particle depolarization ratios are less than 0.15 at 532 nm. The fine-mode fraction of the size distributions decreases and the coarse-mode fraction of the size distribution increases for increasing linear particle depolarization ratio at 1020 nm. The dust ratio based on using the linear particle depolarization ratio derived from AERONET data is 0.12 to 0.17. These values are lower than the coarse-mode fraction derived from the volume concentrations of particle size distributions, in which case we can compute the coarse-mode fraction of dust.
  • Regional and local variations in atmospheric aerosols using ground-based sun photometry during Distributed Regional Aerosol Gridded Observation Networks (DRAGON) in 2012, Itaru Sano, Sonoyo Mukai, Makiko Nakata, Brent N.

    Summary:Aerosol mass concentrations are affected by local emissions as well as long-range transboundary (LRT) aerosols. This work investigates regional and local variations of aerosols based on Distributed Regional Aerosol Gridded Observation Networks (DRAGON). We constructed DRAGON-Japan and DRAGON-Osaka in spring of 2012. The former network covers almost all of Japan in order to obtain aerosol information in regional scale over Japanese islands. It was determined from the DRAGON-Japan campaign that the values of aerosol optical thickness (AOT) decrease from west to east during an aerosol episode. In fact, the highest AOT was recorded at Fukue Island at the western end of the network, and the value was much higher than that of urban areas. The latter network (DRAGON-Osaka) was set as a dense instrument network in the megalopolis of Osaka, with a population of 12 million, to better understand local aerosol dynamics in urban areas. AOT was further measured with a mobile sun photometer attached to a car. This transect information showed that aerosol concentrations rapidly changed in time and space together when most of the Osaka area was covered with moderate LRT aerosols. The combined use of the dense instrument network (DRAGON-Osaka) and high-frequency measurements provides the motion of aerosol advection, which coincides with the wind vector around the layer between 700 and 850 hPa as provided by the reanalysis data of the National Centers for Environmental Prediction (NCEP).
  • RELATION BETWEEN AEROSOL CHARACTERISTICS AND IMPACT FACTOR ON CLIMATE AND ENVIRONMENT, Makiko Nakata, Itaru Sano, Sonoyo Mukai, 2015 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM (IGARSS), 2015 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM (IGARSS), 2342 - 2345, 2015
    Summary:Aerosol impacts on Earth's system are not negligible. The change of concentration of aerosols causes various effects on the climate by directly and indirectly modifying the optical properties and lifetimes of cloud. In addition to radiation budget change, aerosol has a significant potential to change cloud and precipitation. East Asia is the area with high concentration of aerosols in the world. This work intends to investigate distribution of aerosols over East Asia and estimate impacts of aerosol on regional climate change using by satellite data and GCM simulations. Aerosol impacts on climate over East Asia is larger than global mean. The simulated results show that surface cooling and weaken monsoon circulation by aerosol effects.

    Summary:The concentration of air pollutants has become severe, and influence of biomass burning aerosols (BBA) generated by agricultural biomass burning (ABB) has been noted upon the severe haze episodes. This work intends to show the retrieval algorithm as far as heavy air pollution caused by ABB is concerned. Aerosol retrieval in the hazy atmosphere is achieved based on radiation simulation method of successive order of scattering (MSOS) for the moderate resolution imaging spectroradiometer (MODIS) on AQUA data. Multi-angle observations with the polarization and directionality of the Earth's reflectances (POLDER) on the polarization & anisotropy of reflectances for atmospheric sciences coupled with observations from a lidar (PARASOL) are available for aerosol retrieval from a mixture of cloud and haze.
  • RETRIEVAL FOR PM2.5 DISTRIBUTION FROM SPACE, Itaru Sano, Sonoyo Mukai, Makiko Nakata, 2015 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM (IGARSS), 2015 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM (IGARSS), 2206 - 2209, 2015
    Summary:Concentration of particulate matter (PM2.5) is a good indicator of air pollution by anthropogenic aerosols in particular near surface. However instrumentation of PM2.5 is still on going in East Asia even in Japan. This work intends to develop an algorithm for estimating PM2.5 distribution based on the satellite measurements. Combined use of satellite derived columnar aerosol optical thickness (AOT) and vertical distribution of aerosol extinction by ground-based LIDAR measurements is available for estimation of near surface AOT. Thus the derived correlation between AOT and PM2.5 is utilized to retrieve satellite based PM2.5.

    Summary:This work intends to consider the retrieval algorithms of remote sensing for severe air pollutions. In these cases mixture of aerosols and clouds, namely aerosols in cloudy scenes and/or clouds in heavy aerosol episode, are often occurred. Aerosol retrieval in the hazy atmosphere has been achieved based on radiation simulation method of successive order of scattering (MSOS). JAXA has been developing the new Earth observing system GCOM-C satellite. GCOM-C will be launched in early of 2017 and board the polarization sensor SGLI. The SGLI has multi (19)-channels as MODIS and measures polarized reflected sunlight at wavelengths of 0.679 mu m and 0.869 mu m as POLDER. The radiance and polarization degree are taken into account here in the severe biomass burning episode over Borneo islands in Indonesia observed by PARASOL. / POLDER and Aqua/MODIS. As a result the possibility of JAXA / GCOM-C / SGLI related to remote sensing for a mixture case of aerosols and clouds can be examined.

    Summary:Air pollution in East Asia has become severe in recent years, with heavy air pollutants and Asian dust being transported from China to neighboring countries throughout the year. In this study, we focus on heavy haze event occurring around Beijing in June, when a serious aerosol episode was detected by both satellite and ground measurements. Retrieval of atmospheric aerosol characteristics from satellite is achieved by radiative transfer simulation in the Earth atmosphere model. The aerosol model is compiled from the worldwide aerosol monitoring network (NASA/AERONET). It is shown here that the radiative transfer problem in the case of aerosol episode is solved by a method of successive order of scattering. In addition we conclude that air pollution around Beijing in June is mainly due to increasing emissions of the anthropogenic aerosols, furthermore carbonaceous aerosols from agriculture biomass burning in Southeast Asia also contribute to the pollution.
  • Suspended particulate matter sampling at an urban AERONET site in Japan, part 2: relationship between column aerosol optical thickness and PM2.5 concentration, Itaru Sano, Makiko Mukai, Nobukazu Iguchi, Sonoyo Mukai, JOURNAL OF APPLIED REMOTE SENSING, JOURNAL OF APPLIED REMOTE SENSING, 4, Feb. 2010 , Refereed
    Summary:The concentration of suspended particulate matter smaller than 2.5 mu m (PM2.5) was linearly correlated with the column aerosol optical thickness (AOT) based on simultaneous measurements at a NASA/AERONET station at Kinki University Campus, Higashi-Osaka, Japan, between March 2004 and June 2006. The correlation coefficient differed with the aerosol type, being maximal when PM2.5 values were measured 120 minutes after AOT data for a dust episode, but almost independent of the time difference between measurements for anthropogenic aerosols. The obtained results were validated using data obtained at the Higashi-Osaka and Noto sites. Our results suggest that the PM2.5 mass concentration can be estimated from the AOT, and vice versa, and hence a distribution map of PM2.5 can be produced from the satellite-derived AOT map determined from the Aqua/MODIS sensor.

    Summary:The aerosol properties of urban atmospheric particles have been analyzed for radiometry data obtained using a multi-spectral photometer located at a NASA/AERONET station at Kinki University Campus, Higashi-Osaka, Japan, since 2002. The suspended particulate matter has been simultaneously measured at the same AERONET site since 2004. Our measurements and a clustering analysis reveal the aerosol types over the industrial city of Higashi-Osaka. It is shown that aerosols at Higashi-Osaka can be classified into three categories: (1) ordinary, which represents the background clear atmosphere of Higashi-Osaka, (2) anthropogenic aerosol events, and (2) dust episodes called Kosa, when large amounts of soil dust are transported to Higashi-Osaka from the Chinese mainland on westerly winds, especially in spring. We also found that the linear correlation exists between column aerosol optical thickness and PM2.5 concentration, and the correlation is better within each aerosol cluster than overall.

    Summary:For a better understanding of urban aerosols, sun/sky photometry has been undertaken at the Kinki University campus in Higashi-Osaka as a NASA/AERONET station since 2002. A new instrument, the SPM-613D (Kimoto Electric), has been taking measurements at the same site since March 15, 2004. The relationship between aerosol properties obtained from radiometry with AERONET and the SPM measurements is examined. It is found that there is a linear correlation between SPM concentrations and aerosol properties, which indicates that aerosol characteristics can be estimated from SPM data, and vice versa. It is also shown that the air quality of the Higashi-Osaka site is poor due to not only the anthropogenic particles by local emissions, such as diesel vehicles and chemical industries, but also due to the dust particles coming from continental desert areas by large scale climatic conditions.

    Summary:This work describes a procedure to retrieve aerosol characteristics, e.g., optical thickness of aerosols at a wavelength of 0.55 mum and its Angstrom exponent, all over the world from Polarization and Directionality of Earth Surface (POLDER) data acquired on board the Advanced Earth Observing Satellite-1 (ADEOS-1). The two parameters indicate the basic information, amount and particle size, respectively. The derived global map, presented in a color plate consisted of optical thickness and Angstrom exponent of aerosols is useful to monitor aerosol distribution. It is found that aerosol loading in central Africa and Asia is always high throughout the year. The results retrieved from ADEOS/POLDER are validated with NASA/AERONET (Aerosol Robotic Network) data.

    Summary:This work attempts to provide a better atmospheric correction For space-based data obtained with second-generation ocean color sensors, e.g., ADEOS (Advanced Earth Observing Satellite)/OCTS (Ocean Color and Temperature Scanner) and POLDER (Polarization and Directionality of Earth Reflectance). Before atmospheric correction, it is necessary to estimate the optical properties of atmospheric aerosols, and then phytoplankton pigment concentration near the sea surface is obtained after atmospheric correction. In other words, this paper deals with the inverse problem of determining such physical quantities as aerosols and phytoplankton using indirect space-based measurements. Our algorithm is based on an estimation of unknown parameters in the scattering systems observed remotely by satellite. (C) 2000 Elsevier Science Inc. All rights reserved.

    Summary:This paper describes a processing flow to extract aerosol characteristics on a global scale from polarization and directionality of Earth reflectance (POLDER) level 1 data. POLDER provides radiance and polarization in the visible and near-infrared regions. Our procedure is composed of two phases; one is a data reduction process from the POLDER level 1 to the global scale, and the other is the aerosol retrieval process. The retrieval algorithm is achieved in practice using a look-up table which is compiled based on multiple scattering simulations in an atmosphere-sea surface system. Monthly global distribution maps showing the Angstrom exponent and the optical thickness of aerosols were obtained in November 1996 and in January and April 1997. From these aerosol maps, it can be seen that: (1) the aerosol distribution derived from POLDER radiance and polarization data coincides with the radiance data obtained independently from OCTS, (2) atmospheric aerosols exhibit certain intrinsic feature on a global and on a seasonal scale.

    Summary:It is well known that the heavy soil dust has been transported from the China continent to Japan on westerly winds, especially in spring. The satellite observation is an effective tool for global monitoring of the Asian dust. A new algorithm for detection of Asian dust from space is proposed based on the multispectral satellite data. The derived space-based results are validated with the ground-based measurements and/or model simulations.<BR>The sun/sky photometry has been undertaken at NASA/AERONET stations at Osaka. The suspended particulate matter (SPM) sampling and NIES/LIDAR network equipment have been simultaneously working there. However, it is difficult to relate these ground-based measurements directly to the column space data. Therefore, in order to validate the satellite results with the surface-level data, an aerosol transportation model should be simulated. The measurements are examined with the model simulations.<BR>As a result, the distribution of Asian dust aerosols is retrieved in a comprehensive way in this study.

    Summary:Using ADEOS-II/GLI aerosol and cloud products, downward and upward solar radiation at the surface and at the top of the atmosphere are estimated to study the Earth radiation budget. There is a good agreement in the main features of the global distribution of radiative fluxes as derived from GLI and from Terra/MODIS, yet, some differences can be noticed and need to be explained. In order to evaluate satellite-retrieved parameters that play a role in the Earth radiation budget, an observational network known as SKYNET has been established in Eastern Asia and it has already been operational during the ADEOS-II/GLI launch. Specifically, observations from the newly developed <I>i-</I>sky radiometer have been used for aerosol and cloud product evaluation. The aerosol products have been found to be in good agreement with observations while the cloud products need further evaluation.
  • Retrieval Algorithm Based on Combined Use of POLDER and GLI Data for Biomass Aerosols, SANO Itaru, OKADA Yasuhiko, MUKAI Makiko, MUKAI Sonoyo, Journal of The Remote Sensing Society of Japan, 29, 1, 54, 59,   2009 01 31 , 10.11440/rssj.29.54, http://ci.nii.ac.jp/naid/10024788473
    Summary:A procedure for aerosol retrieval by combining data provided by POLDER (Polarization and Directionality of the Earth's Reflectances) and GLI (Global Imager) sensors mounted on the ADEOS-2 satellite (Advanced Earth Observing Satellite-2) is proposed. The POLDER sensor provides three channels of unique directional polarization measurements, and the GLI sensor provides high-resolution images over a wide range of wavelengths from near-UV to thermal infrared. It is known that POLDER polarization data are effective for aerosol retrieval over land, and the ratio of reflectances at 0.40 and 0.38μm from GLI can be used to distinguish between nonabsorbing and absorbing aerosols. Our algorithm is tested by detecting the plume from Siberian biomass burning in May 2003. The retrieved aerosol properties are compared with model simulations and ground-based AERONET (Aerosol Robotic Network) data. The results show that our proposed algorithm provides improved data on the aerosol optical thickness.

    Summary:In order to analyze the urban atmospheric particles in Asia, we have undertaken simultaneous measurements of aerosols and suspended particulate matter (SPM) at a NASA/AERONET station at Kinki University Campus, Higashi-Osaka, since March in 2004. The relationship between concentration of suspended particulate matter (PM) and column aerosol optical thickness (AOT) is examined. It is found that a strong linear correlation exists between PM and AOT, and better correlation is obtained for the aerosols with the same origin, such as anthropogenic aerosols and dusts, rather than overall. The derived regression lines between PM<SUB>2.5</SUB> and AOT highlight the possibility that the PM<SUB>2.5</SUB> concentration can be estimated from the AOT, and vice versa. As a result, a distribution map of PM<SUB>2.5</SUB> has been obtained by using AOT values derived from Terra/MODIS data observed in April 2006 over East Asia.
  • A Study of Aerosol and Cloud Information Retrievals from CAI Imager on Board GOSAT Satellite, NAKAJIMA Teruyuki, NAKAJIMA Takashi Y, HIGURASHI Akiko, SANO Itaru, TAKAMURA Tamio, ISHIDA Haruma, SCHUTGENS Nick, Journal of The Remote Sensing Society of Japan, 28, 2, 178, 189,   2008 04 30 , 10.11440/rssj.28.178, http://ci.nii.ac.jp/naid/10024344169
    Summary:The GOSAT satellite has been designed for retrieving the carbon dioxide amount in the atmosphere by a Fourier transform spectro-radiometer (TANSO-FTS). It is, however, known that FTS-observed radiances in the near-infrared spectral region are heavily contaminated by a solar radiation component scattered by atmospheric aerosols, which is known as "path radiance". In order to correct the path radiance, a multispectral visible-near infrared imager (TANSO-CAI) will be on board the GOSAT satellite to acquire the aerosol and cloud information that is indispensable for correcting the atmospheric path radiance to improve the carbon dioxide remote sensing by FTS. In this article, we study aerosol retrieval algorithms and cloud screening algorithms using the four channel radiances of CAI. We also present the methodology for vicarious calibration and validation for the CAI remote sensing, intercomparison of CAI-retrieved aerosol products with those from other satellite-borne sensors, and the data fusion strategy of satellite-measured and model-simulated aerosol properties.
  • Individual particle analysis of Asian dust-storm particles over Higashiosaka in 2005 and 2006, NAKAGUCHI Yuzuru, HAMADA Hiroshi, SUYAMA Yuki, SANO Itaru, MUKAI Sonoyo, 41, 4, 155, 163,   2007 12 28 , 10.14934/chikyukagaku.41.155, http://ci.nii.ac.jp/naid/110009442221
    Summary:The particle samples over Higashiosaka were collected by personal air sampler during asian-dust storms in April of 2005 and 2006. The size and elemental composition of individual perticles were investigated by scanning electron microprobe equipped energy-dispersive X-ray analyzer. From the results of individual particle analysis of Asian dust storm particles, Si-rich particles occupied 76.0% in 2.5-10.0μm diameter particles and 93.0% in <2.5μm diameter particles in April of 2005. In April 2006, Si-rich particles occupied 97.0% in 2.5-10.0μm diameter particles and 99.7% in <2.5μm diameter particles. Anthropogenic sulfur contaminated particles without sea salt were occupied by 2.2% in 2.5-10.0μm diameter particles and 3.6% in <2.5μm diameter particles in April 2005, and those were occupied by 0.4% in 2.5-10.0μm diameter particles and 2.9% in less than 2.5μm diameter particles in April 2006. From these results we confirmed that the degree of adsorption of anthropogenic sulfur oxides on to Asian dust storm particles during transport process from China to Japan was small in 2005 and 2006 over Higashiosaka.

    Summary:To monitor urban atmospheric particles, we have undertaken simultaneous measurements of aerosols and suspended particulate matter (SPM) at Kinki University Campus, Higashi-Osaka, Japan, since 2004. The largest dust event recorded during our long-term observations was detected during the spring of 2006. We also examined the relationship between PM_<2.5> concentrations and aerosol properties obtained from radiometry using a multi-spectral photometer located at a NASA/AERONET station. We found a linear correlation between aerosol optical thickness and PM_<2.5> concentrations for both ordinary days and days with dust events. This fact indicates that aerosol characteristics can be estimated from SPM data, and vice versa. Combining radiometric aerosol information with surface-level particulate mass measurements is useful in studying air quality and aerosol properties.

    Summary:This paper presents the photopolarimetric measurements of atmospheric aerosols with a portable multi-spectral polarimeter.

The PSR-1000 observes radiance of the direct sunlight, which provides Angstrom exponent as well as aerosol optical thickness, and radiance and polarization of atmospheric light, which is available to extract other information of aerosol characteristics. The sensor calibration of PSR-1000 is important to keep the accuracy of AOT. The extraterrestrial outputs of PSR-1000 were obtained at Mt. Mauna-Loa in Hawaii Island and at Mt. Haleakala in Maui Island and so on to get the calibration constants of PSR-1000 based on Langley plot method involving gaseous absorption. It is shown that the relation between polarization degree and aerosol optical characteristics.

    Summary:Simultaneous measurements of atmospheric aerosols and suspended particulate matter (SPM) have been undertaken at Kinki University campus in Higashi-Osaka in order to monitor the urban environment. The sun/sky photometry has been made as a NASA/AERONET station since 2002, and the SPM-613D (Kimoto Electric) has been taking measurements of the SPM concentrations such as TSP, PM_<10>, PM_<2.5>, and OBC at the same site since March 15, 2004. The relationship between aerosol properties obtained from radiometry with AERONET and the SPM measurements is examined. It is found that there is a linear correlation between SPM concentrations and aerosol properties, which indicates that aerosol characteristics can be estimated from SPM data, and vice versa. Furthermore chemical analysis of the SPM sampling strongly suggests the really complicated features of the atmospheric particles at Higashi-Osaka. In other words, it is shown that the air quality of the Higashi-Osaka site is poor due to not only anthropogenic particles by local emissions, such as diesel vehicles and chemical industries, but also due to dust particles coming from continental desert areas by large scale climatic conditions.

    Summary:Our sun/sky photopolarimetric measurements of atmospheric light have been undertaken at Fukuejima since 2002, and at Higashi-Osaka since 2003. The cloud-screening algorithm is described first, and then aerosol optical thickness and Angstrom exponent are derived from the data after processing of the cloud-screening at Fukuejima and Higashi-Osaka. It is shown that aerosol characteristics are different from each other between Fukuejima and Higashi-Osaka.

    Summary:Satellite remote sensing plays an important role for monitoring of the Earth environment and global climatology. It is well known that combination use of multi satellite and /or sensor data is desired for high quality products. For instance, the POLDER and GLI sensors have been mounted on the satellite ADEOS-2 and working during April to October in 2003. Each sensor has each characteristic, e.g. POLDER provides the multi angle polarization data and GLI gives the high resolved images. This work intends to develop a processing system for combination use of both sensor data. It is shown that detection of cloud coverage of POLDER data is practically improved with GLI data. As a result, effective retrieval of aerosols and cloud particles will be made.

    Summary:The relationship is examined between aerosol properties obtained from radiometry with AERONET and the particulate mass simultaneously measured with a new instrument (SPM-613D). The AERONET site has been set up at Higashi-Osaka since 2002 to make measurements for understanding the characteristic features of the urban atmosphere. It is found that the SPM measurements classified as fine particles (PM2.5), coarse particles (TSP/PM10), and optical black carbon (OBC) are very useful for determining the dominating of particle size and air quality. There was a strong correlation between the SPM concentrations and aerosol properties (AOT/AI), which indicates that aerosol characteristics can be estimated from SPM data, and vice versa.
  • Chlorophyll-a concentration in the inland sea from ADEOS/AVNIR, Yasumoto Masayoshi, Mukai Sonoyo, Sano Itaru, Tamai Motoharu, Science and technology, 16, 41, 53,   2004 02 28 , http://ci.nii.ac.jp/naid/110004713819
    Summary:We intend to propose an effective procedure of monitoring the water quality in the inland sea from space. Retrieval of chlorophyll-a concentration, which is a typical indicator of the water environment, from the satellite data is called ocean color remote sensing. Ocean color sensors are designed to observe the ocean with rather coarse spatial resolution in general. Inland sea analysis demands the precise geographical information, and hence high resolution satellite images are requires for our present study. In practice, ADEOS/AVNIR data is examined to monitor the chlorophyll-a concentration in Ise bay and Kushiro port. Chlorophyll-a concentration is estimated from the ratio of water-leaving radiance at a wavelength of 0.560μm to that at 0.460 μm after atmosphere correction on AVNIR data. Aerosol optical properties for atmospheric correction of AVNIR data are retrieved from near-infrared data of 0.670 and 0.865μm given by ADEOS/OCTS and POLDER. It is shown that AVNIR data are available to monitor the water quality in the inland sea.

    Summary:This paper presents the photopolarimetric measurements of atmospheric aerosols with a portable multi-spectral polarimeter, Opt-Research PSR-1000, which has six observing wavelength bands corresponding to the ADEOS/POLDER sensor. The measurements have been undertaken at Kinki University campus in Higashi-Osaka city and Seto Inland Sea in Japan, Mandalgobi in Mongol, East-China Sea Western Australia and west-Pacific Ocean on clear days since 1996. The PSR-1000 observes radiance of the direct sunlight, which provides Angstrom exponent as well as optical thickness of aerosols, and radiance and polarization of atmospheric light, which is available to extract other information of aerosol characteristics. It is found that the data clearly show the typical yellow sand events over the Asian Pacific Ocean in spring, and the spatial change of aerosol properties.

    Summary:A portable multispectral polarimeter named PSR-1000, which has the same observing bands as ADEOS/POLDER, has been introduced since 1996. PSR-1000 is designed to measure direct solar radiation and diffuse sky radiation. First of all, a calibration of the PSR-1000 was done based on Langley plot method involving gaseous absorption from October 27 to November 2 in 1997 at Mt. Mauna Kea in Hawaii Island. Then the measurements of polarization and optical thickness of aerosols with the PSR-1000 were undertaken over the ocean around Shikoku Island of Japan in 1997, 1998 and 1999. It is found that the relationship in respect of wavelength dependency between the observed optical thickness and degree of polarization is classified into two groups. The measurements are available to retrieve the optical characteristics of aerosols, e.g., refractive index, size distribution parameters, based on light scattering simulations in the polarization field. From the retrieved results, it can be seen that; (1) heterogeneous particles are good a candidate for our aerosols, (2) contamination rate of water-soluble inclusions to the oceanic matrix of heterogeneous model aerosol decreases from inland to the open sea.

These data as well as polarization measurements are applied to retrieve optical properties of aerosols based on simulations of polarization field. We found that the seasonal change is detected as concerned with continental aerosols.
