AERDB_M3_AHI_H08 - AHI/Himawari-08 Deep Blue Level 3 monthly aerosol data, 1x1 degree grid

The Level-3 (L3) Advanced Himawari Imager (AHI) Himawari-8 Deep Blue Aerosol Deep Blue Monthly Aerosol dataset is part of a 12-product suite produced by an Earth Science Research from Operational Geostationary Satellite Systems (ESROGSS)-funded project. The 12 products in this project include nine derived from three Geostationary Earth Observation (GEO) instruments and three from merged data from GEO and Low-Earth Orbit (LEO) instruments as summarized in the following table:

• includes G16-ABI, G17-ABI, H08-AHI, SNPP-VIIRS, NOAA20-VIIRS, Terra MODIS & Aqua MODIS

Derived by aggregating the L3 daily (AERDB_D3_AHI_H08) input data, each M3 AHI/ Himawari-8 product is produced monthly at 1 x 1-degree horizontal resolution. This monthly L3 (identified in the shortname as M3) product’s statistics that include mean and standard deviation of the daily means are derived from the arithmetic mean values of the L3 daily product. As a mechanism to filter out poorly sampled grid elements, at least three valid days of data in the month are required to populate the monthly grid element. This first release of these products spans from May 2019 through April 2020 with a potential to generate additional temporal coverage in the future.

Each L3 aggregated monthly AHI/ Himawari-8 datafile contains 48 Science Data Sets (SDS) that include the following:
