We are pleased to announce that the Version 1 VIIRS Deep Blue aerosol data set is available. Deep Blue product provides aerosol optical depth at 550 nm among other quantities, using the Deep Blue (DB) algorithm over land and Satellite Ocean Aerosol Retrieval (SOAR) algorithm over ocean.
Level 2 data are provided in 6-minute granules, at approximately 6 km x 6 km pixel size at the sub-satellite point. Level 3 daily (D3) and monthly (M3) composites at 1 degree horizontal resolution are also available. All files are in NetCDF4 format.
The data set is available through the LAADS DAAC and EarthData:
