GEO-LEO Merged Deep Blue Aerosol 0.25x0.25 degree Gridded L2
The GEO-LEO Merged Deep Blue Aerosol 0.25x0.25 degree Gridded L2 product, short-name AERDB_L2G_GEOLEO_Merged contains gridded Aerosol Optical Thickness (AOT) at 550 nm reference wavelength, derived from seven merged GEO-LEO AOT layers (G16-ABI, G17-ABI, H08-AHI, SNPP-VIIRS, NOAA20-VIIRS, Terra MODIS and Aqua MODIS) and from each of the individual (three GEO and four LEO) instrument sources. Each L2G aggregated datafile is spatially comprised of a 0.25˚ x 0.25˚ horizontal grid that exists for every 30 minutes. This represents a 30-minute Deep Blue best-estimate AOT from each of the seven sources besides an error-weighted merged AOT layer. This first release of these products spans from May 2019 through April 2020 with a potential to generate additional temporal coverage in the future. The Level-2G (L2G) Geostationary Earth Orbit (GEO)-Low-Earth Orbit (LEO) Merged Deep Blue Aerosol 0.25 x 0.25-degree Gridded 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.The AERDB_L2G_GEOLEO_Merged product, in netCDF4 format, contains 16 GEO-LEO Merged Group Science Data Set (SDS) layers and 15 GEO and LEO SDSs.
