Comparison of hourly aerosol retrievals from JAXA Himawari/AHI in version 3.0 and a simple customized method
Abstract Advanced Himawari imager (AHI) carried on the new-generation geostationary meteorological Himawari-8 satellite of Japan has been generating aerosol observations with a high temporal resolution since 7 July 2015. However, the previous studies lack a comprehensive quality assessment and spati...

AHI AOD products indicated an obvious underestimation when compared to MODIS AOD retrievals over both land and ocean.
