2010年春季と秋季の黄砂現象 2010ネン シュンキ ト シュウキ ノ コウサ ゲンショウ Asian Dust Events in the Spring and Autumn of 2010 飯野, 直子 イイノ, ナオコ Iino, Naoko 後藤, 将太 ゴトウ, ショウタ Goto, Shota 中村, 恭浩 ナカムラ, ヤスヒロ Nakamura, Yasuhiro 金柿, 主税 カナガキ, チカラ Kanagaki, Chikara 451.5 MTSAT Brightness temperature difference image Suspended Particulate Matter Visibility Ground-based time-lapse image The advection and dispersion of Asian dust events from China to the Pacific Ocean around Japan in 2010 were investigated using the Multi-functional Transport Satellite (MTSAT) data. Aerosol Vapour Index images, taking the brightness temperature difference between 11 μm and 12 μm, were very effective for monitoring the Asian dust phenomenon in the East Asia region, with their capacity for detection during the day or night. The results were compared with suspended particulate matter concentrations measured at surface stations in Kyushu and with ground-based observations of sky in Kumamoto and Kagoshima. When a dense dust band was crossing over Japan, the rapid increase of SPM concentrations was observed at stations located in the dust path. The observed increase of SPM concentrations corresponded to the distribution of Asian dust shown in AVI images, the visibilities recorded by the Janan Meteorological Agency and the atmospheric turbidity shown in the ground-observation images. 熊本大学 2012-12-12 jpn departmental bulletin paper VoR http://hdl.handle.net/2298/26562 https://kumadai.repo.nii.ac.jp/records/26913 0454-6148 AN10315071 熊本大学教育学部紀要 自然科学 61 39 46 https://kumadai.repo.nii.ac.jp/record/26913/files/KN0061_039-046.pdf application/pdf 9.1 MB 2020-03-02
