NOAA JPSS Visible Infrared Imaging Radiometer Suite (VIIRS) Level-4 1-Day and 5-Day Composite Flood Maps from NDE

This Level-4 (L4) Global Environmental Data Record (EDR) provides blended 1-Day and 5-Day composite flood products produced from observations acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi-NPP and NOAA-20 satellites. These composite products are rendered using Area of Interest (AOI) maps. The globe is divided into 134 AOI maps, with each map providing the maximum 1-Day or 5-Day flood extent for that AOI. The 1-Day product is generated by compositing VIIRS Flood Map EDR granules into AOI maps and the 5-Day product is generated by aggregating the 1-Day maps over a five day period. This data set is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and is distributed by the Comprehensive Large Array-Data Stewardship System (CLASS) as aggregated 375 meter grids in the NetCDF file format with metadata attributes included.
