Aerosol Optical Thickness over the Oceans Derived from GMS-5 during Spring 2002 and 2003

Abstract

Daily and monthly aerosol optical thickness (AOT) over the ocean, derived from the Geostationary Meteorological Satellite (GMS-5) visible data, were compared with those determined from the sun photometer measurements in March and April 2002. Time variations in the daily AOT derived from the GMS-5 showed good agreements with those from the sun photometer measurements. Correlation coefficient between the GMS-5 and the sun photometer derived daily AOTs was 0.85 for 61 samples taken at three sun photometer observation sites; Ryori, Yonagunijima, and Minamitorishima in Japan.

Aeolian dust experiment on climate impact: An overview of Japan–China joint project ADEC

“…Rizan, southwestern Japan . (4) we analyzed the time series of the horizontal distribution of dust aerosol optical thickness derived from the GMS-5 (GMS: Geostationary Meteorological Satellite; Masuda et al, 2005) to monitor the horizontal distribution of dust in East Asia. (5) we developed two categories of dust model; regional scale models for understanding dust outbreaks and their transport processes and a global scale dust model for the evaluation of the direct effect of RF due to dust.…”

“…Quantification of anthropogenically disturbed dust caused by over grazing and inappropriate cultivation of land and/or water management in semi-arid regions is required. ii) While monitoring of dust over oceans has been achieved using GMS-5 (Masuda et al, , 2005 during ADEC experiments, in order to monitor the horizontal distribution of dust and to validate the dust model, horizontal information of dust over land is required. A retrieval technique using satellite data is still in the development stage (e.g.…”

Evaluating Aerosol Optical Depth From Himawari‐8 With Sun Photometer Network

“…While AODs retrieved from LEO satellites have a low temporal sampling rate of only once or a few times daily for most regions, this can be overcome by geostationary satellites, which observe Earth and the atmospheric system at a much higher temporal resolution (Wang et al, 2019;Yumimoto et al, 2016). Therefore, more and more attention has been paid to aerosol retrieval using geostationary satellites, such as the Geostationary Operational Environmental Satellite (Knapp, 2002;Knapp et al, 2005), Geostationary Meteorological Satellite (Masuda et al, 2005), Multifunction Transport Satellite (Kim et al, 2008), and FengYun-4 (Lyu et al, 2017).…”
