SNPP VIIRS Deep Blue Level 3 monthly Aerosol Data, 1x1 Degree Grid - V2.1
Listed in NASA Earthdata CMR
Description
The Visible Infrared Imaging Radiometer Suite (VIIRS) NASA standard Level 3 (L3) monthly Deep Blue Aerosol Products from the Suomi National Polar-orbiting Partnership (SNPP) instrument provide satellite-derived measurements of Aerosol Optical Thickness (AOT) and their properties over land and ocean as gridded aggregates, globally on a monthly basis. The Deep Blue algorithm draws its heritage from previous applications to retrieve AOT from Sea‐viewing Wide Field‐of‐view Sensor (SeaWiFS) over both land and ocean, and Moderate Resolution Imaging Spectroradiometer (MODIS) measurements over land.
This monthly aggregated product (Short-name: AERDB_M3_VIIRS_SNPP) is derived from the Version 2.1 (v2.1) daily L3 gridded products (AERDB_D3_VIIRS_SNPP) and is provided in a 1 ° x 1 ° horizontal-resolution grid. Arithmetic mean values from the daily L3 gridded products also provide the basis to derive a complement of statistics for the monthly aggregated products. To exclude poorly sampled grid elements, the algorithm requires at least 3 valid days’ worth of data to render a given monthly grid element as valid.
