    VIIRS/NOAA20 Deep Blue Level 3 daily aerosol data, 1 degree x 1 degree grid

    Metadata Updated: February 22, 2025

    The VIIRS/NOAA20 Deep Blue Level 3 daily aerosol data, 1x1 degree grid, Short-name AERDB_D3_VIIRS_NOAA20 product is derived from the Version-2.0 (V2.0) L2 6-minute swath-based products (AERDB_L2_VIIRS_NOAA20), and is provided in a 1x1 degree horizontal resolution grid. Each data field, in most cases, represents the arithmetic mean of all the cells whose latitude and longitude coordinates positions them within each grid element’s bounding limits. Other measures like standard deviation are also provided. This aggregated product is derived only using the best-estimate, QA-filtered retrievals. Using only cells that were measured on the day of interest, the algorithm requires at least three retrieved measurements to render a given grid as valid on any given day. This daily product record starts from January 5th, 2018. This L3 daily product, in netCDF, contains 45 Science Data Set (SDS) layers.
