Earth Observation Research Center (EORC) of Japan Aerospace Exploration Agency (JAXA) is developing the aerosol product retrieved from AHI data. The retrieval algorithm is same as that developed for the upcoming earth observation satellite, Global Change Observation Mission - Climate (GCOM-C), which is based on the schemes by Higurashi and Nakajima (1999, 2002) over land and Fukuda et al. (2013) over ocean. In order to apply the algorithm to AHI, we used its 0.51Ám and 0.64 Ám channels for land and 0.64 Ám 0.86 Ám channels for ocean. Using the response function of AHI, we constructed the look-up-tables by the radiation transfer package of STAR series (Nakajima and Tanaka 1986, 1999; Ota et al. 2009). The clear sky pixels were selected by using the CLAUDIA algorithm (Ishida and Nakajima 2009; Ishida et al. 2011) which was developed for GOSAT/CAI, GCOM-C/SGLI and EarthCARE/MSI.
The JAXA Himawari-8 aerosol product is expected to be disseminated with the L1b reflectance/radiance product in netCDF every one hour. After a simple user registration, users will be able to download the dataset freely from JAXA/EORC Homepage.
