    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.

    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. Opto-Research PSR-1000, which has six observing wavelength bands. The measurements have been undertaken at Kinki University campus in Higashi-Osaka on clear days since 1996. 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.
  • Aerosol Properties and Air Pollutants over Higashi-Osaka, Mukai Sonoyo, Nakaguchi Yuzuru, Sano Itaru, Yasumoto Masayoshi, Matoba Yukihiro, Science and technology, 17, 15, 25,   2005 02 28 , http://ci.nii.ac.jp/naid/110004636324
    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:This work proposes the combined use of ADEOS/POLDER- and OCTS-data for detection of the cloud coverage and its thermodynamic phase. On the basis of the satellite date obtained on November 10 in 1996, it is shown that infrared data at a wavelength of 10.9μm given by OCTS and near-infrared polarized reflectance at 0.865μm over wide range of scattering angle provided by POLDER are available for cloud screening and for classification of the thermodynamic phase of cloud top into ice and water..

    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.
