Collection 1 - SNPP Atmosphere Product Descriptions: VIIRS Daily Level 3 Deep Blue Aerosol
Last update: October 12, 2018
Data Set Short Name:
AERDB_D3_VIIRS_SNPP
Data Set Long Name:
VIIRS/SNPP Deep Blue Level 3 daily aerosol data, 1x1 degree grid
Platform:
Suomi National Polar-Orbiting Partnership (S-NPP)
Instrument:
Visible-Infrared Imaging-Radiometer Suite (VIIRS)
Product Description:
The Deep Blue aerosol product from the Visible Infrared Imaging Radiometer Suite (VIIRS) uses the Deep Blue (DB)
algorithm over land and Satellite Ocean Aerosol Retrieval (SOAR) algorithm over water to determine atmospheric
aerosol loading for daytime cloud-free snow-free scenes. This data product is designed to facilitate continuity in
the aerosol record provided by the Deep Blue aerosol project for other sensors including the Sea-viewing Wide Field-
of-view Sensor (SeaWiFS) and Terra/Aqua Moderate Resolution Imaging Spectroradiometers (MODIS). This is a Level-3
product generated at 1 degree horizontal spatial resolution. It is created by spatiotemporal aggregation of the Level
2 (swath-based) VIIRS Deep Blue product (VNPAERDB_L2) from granules collected over one calendar day, thus gaps in the
aerosol data will appear wherever that does not provide data (e.g. clouds, snow/ice, and polar night).
Production Frequency:
1 file per day
Spatial Coverage:
Global (daytime only)
Spatial Resolution:
1 degree latitude by 1 degree longitude
File Size:
Variable, but typically 3-5 MB
