The atmospheric aerosol distribution in Asia is complex because it is influenced by both natural phenomena and human activities. In this article, multifaceted approach using satellite observations and numerical model simulation shows seasonal and regional variations of the aerosol distribution over Asia. Asia covers a large area however, this article is limited to East and Southeast Asia. The aerosol optical thickness (AOT) in the inland desert area is normally high in spring and dusty aerosols are widely spread with the wind. The AOT values are high in summer over East Asia. A high AOT caused by biomass burning plumes is observed in autumn over Southeast Asia and in spring over Siberia and heavy air pollution occurs in Beijing in winter, a very well-known phenomenon. These phenomena caused by heavy aerosol concentration were determined based on Aqua/MODIS data and aerosol characteristics retrievals and estimated the aerosol characteristics. Furthermore, the impact of aerosols on the climate assessed by numerical model simulations suggest that aerosols reduce solar radiation and therefore the Earth's surface temperature. In addition to these influences on the radiation budget, aerosols have a significant potential to change the circulation fields. - Sonoyo Mukai; Makiko Nakata; Itaru Sano; Masayoshi Yasumoto; Toshiyuki FujitoInternational Geoscience and Remote Sensing Symposium (IGARSS) Institute of Electrical and Electronics Engineers Inc. 2017- 5958 - 5961 2017/12 [Refereed]
It is known that the biomass burning aerosols (BBA) generated by the large-scale forest fires and burn agriculture have influenced the severity of air pollution. Nevertheless the biomass burning plumes increase due to global warming and climate change and vice versa. It is worth noting that the near ultra violet (NUV) measurements are helpful for the detection of carbonaceous particles, which are the main component of aerosols from biomass burning. In this work, improved retrieval algorithms for BBA are interpreted by using the measurements observed by GLI and POLDER-2 on Japanese short term mission ADEOS-2 from December 2002 to October 2003. The GLI sensor has 380nm channel. Finally the obtained optical properties of BBA are investigated from the standpoint of spatial and temporal variations in comparison with the numerical model simulations. - Sonoyo Mukai; Itaru Sano; Makiko Nakata; Masayoshi YasumotoREMOTE SENSING OF CLOUDS AND THE ATMOSPHERE XX SPIE-INT SOC OPTICAL ENGINEERING 9640 0277-786X 2015 [Refereed]
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. - Mukai Sonoyo; Nakata Makiko; Yasumoto Masayoshi; Sano Itaru; Kokhanovsky AlexanderFRONTIERS IN ENVIRONMENTAL SCIENCE FRONTIERS MEDIA SA 3 (57) 1 - 11 2296-665X 2015 [Refereed]
Aerosol distributions in East Asia are complicated owing to both natural factors and human activities. In recent years, influence of yellow sand and biomass burning aerosols generated by agricultural biomass burning (ABB) has been noted upon the severe air pollution episodes. This work intends to make the retrieval algorithm more efficient and to make the aerosol model more tractable 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. The retrieved aerosol properties agree well with the ground measurements and numerical model simulations. 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, and many potential applications of MSOS involving polarization information are expected to be available for cloud as well as aerosol episodes. - Ground and satellite-based measurements of aerosols during heavy haze eventsMasayoshi Yasumoto; Sonoyo Mukai日本応用情報学会誌 ( NAIS Journal ) 9 13 - 19 2014/09 [Refereed]

We investigate heavy haze episodes (with dense concentrations of atmospheric aerosols) occurring around Beijing in June, when serious air pollution was detected by both satellite and ground measurements. Aerosol retrieval is achieved by radiative transfer simulation in an Earth atmosphere model. We solve the radiative transfer problem in the case of haze episodes by successive order of scattering. We conclude that air pollution around Beijing in June is mainly due to increased emissions of anthropogenic aerosols and that carbonaceous aerosols from agriculture biomass burning in Southeast Asia also contribute to pollution. - 向井苑生; 佐野到; 中田真木子; 中口譲; 井口信和; 保本正芳; HOLBEN Brent Nエアロゾル研究 Japan Association of Aerosol Science and Technology 29 (S1) S125-S132 (J-STAGE) - s132 0912-2834 2014 [Refereed]
Aerosol retrieval work from satellite data is divided into three parts: satellite data analysis, aerosol modeling, and multiple light scattering simulations in the atmosphere modeling what is known as the radiative transfer problem. It is well known that the aerosol model has been developed using the accumulated measurements during more than ten years provided with the world-wide aerosol monitoring network (AERONET). The radiative transfer simulations incorporate the Rayleigh scattering by molecules and Mie scattering by aerosols in the atmosphere. Thus the aerosol properties are estimated by comparing satellite measurements with the numerical values of radiation simulations in the Earth-atmosphere model. It is reasonable to consider that the precise simulation of multiple light scattering processes is necessary, and requires a long computational time, especially for an optically thick atmosphere. Therefore, efficient algorithms for radiative transfer problems are indispensable to retrieve aerosols from space. It is shown here that dense aerosol events can be well simulated by a semi infinite radiative-transfer model. For an example, the air pollution event observed by Aqua/MODIS in June of 2010 over Beijing is interpreted based on the proposed aerosol models and the semi-infinite radiative transfer simulation code known as MSOS (Method of Successive Order of Scattering). - Sonoyo Mukai; Masayoshi Yasumoto; Makiko Nakata; Itaru Sano2014 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM (IGARSS) IEEE 4165 - 4168 2153-6996 2014 [Refereed]
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. - Sonoyo Mukai; Itaru Sano; Kotaro Ishii; Masayoshi Yasumoto; Toshiro SugimuraRemote Sensing of the Atmosphere and Clouds II SPIE (The International Society for Optical Engineering) 7152 0277-786X 2008/12 [Refereed]

The relationship between concentration of suspended particulate matter (PM2.5) and column aerosol optical thickness (AOT) is examined based on the simultaneous measurements at a NASA/AERONET station at Kinki University Campus, Higashi-Osaka, Japan since March in 2004. We drew the following results: 1. A strong linear correlation exists between PM2.5 and AOT, 2. The correlation is better within each type of aerosols as anthropogenic type and dust type than overall, 3. The correlation coefficients take the highest value in such a case that PM2.5 values are measured in 30-minutes behind after AOT data. These facts are explained with the model simulations. Our results highlight the possibility that the PM2.5 concentration can be estimated from the AOT, and vice versa. Moreover, combining radiometric aerosol information with surface-level particulate mass data appears to be a promising approach for gaining a better understanding of air quality and the atmospheric environment. - 向井苑生; 佐野到; 保本正芳日本リモートセンシング学会誌 The Remote Sensing Society of Japan 27 (1) 33 - 38 0289-7911 2007/01 [Refereed]
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 PM2.5 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 PM2.5 concentrations for both ordinary days and days with dust events. - Sonoyo Mukai; Itaru Sano; Masayoshi Yasumoto; Mitsuru NishinaREMOTE SENSING OF CLOUDS AND THE ATMOSPHERE XI SPIE-INT SOC OPTICAL ENGINEERING 6362 0277-786X 2006 [Refereed]

Each retrieval algorithm for atmospheric aerosols, clouds and water vapor from ADEOS/POLDER data is described. A POLDER sensor, mounted on the Earth observation satellite ADEOS in 1996, is a unique sensor which can gather multi-directional (up to 14) polarization measurements of one target. Atmospheric aerosol properties as optical thickness and Angstrom exponent are derived from the POLDER polarization data at wavelengths of 0.670 and 0.865 mum. The polarization data at 0.865 mum is also available for cloud retrieval. Two channels in the near infrared wavelengths are used to estimate the total column water vapor content. The first channel is in the water vapor absorption band of 0.910 mum and the second is in the gas absorption-free band of 0.865 mum. In practice, a ratio of each reflectance for these two channels is used in this study. Then the obtained global maps of aerosol properties, cloud microphysics and water vapor content are compared with one another. It is shown that column number density of aerosols has a negative correlation with the effective radius of cloud particles and proportionally correlates with the optical thickness and the column number density of cloud particles. These results confirm the indirect effect of aerosols, namely aerosols play sufficient role as cloud condensation nuclei (CCN). (C) 2003 COSPAR. Published by Elsevier Ltd.

On the basis of the satellite images obtained on November 10, 1996, we show that the cloud detection algorithm for POLDER proposed by CNES tends to overestimate the cloud regions. Better estimation can be obtained by adding a brightness temperature test by means of the OCTS data. A single-scattering simulation, carried out for water droplets and hexagonal ice crystals, indicates that the phase discrimination of the cloud top can be accomplished by comparing the polarized reflection data of POLDER at two scattering angles of 100°and 140°. The result is in reasonable agreement with the classification with the OCTS temperature data.

The basic idea of our aerosol retrieval is that the scattering behavior of aerosols plays a sufficient role in the polarization field of the Earth atmosphere-surface system in the near infrared wavelengths. It is shown that the aerosol loading increases from 1997 to 2003, and aerosol events, which means anomaly lots of aerosol loading, are shown in north-west Africa and east Asia. 2.Ground based photo-polarimetry of aerosols To characterize urban aerosols, sun/sky photometry and polarimetry with PSR-1000 (Opto Research) have been performed over Higashi-Osaka since 1996. Multi-spectral photometer CE-318-2 (Cimel Electronique) was subsequently set up for an AERONET site in 2002. Another AERONET instrument (CE-318-1) has been operating at Shirahama since 2000 as a part of NASA/AERONET. The radiometers at both Osaka and Shirahama were calibrated using a standard AERONET procedure. The new SPM-613D instrument makes it possible to determine the relationship between aerosol properties and the particulate mass
