Collection 1 - SNPP Atmosphere Product Descriptions: VIIRS Monthly Level 3 Deep Blue Aerosol

Last update: October 15, 2018

Data Set Short Name:
AERSDB_M3_VIIRS_SNPP

Data Set Long Name:
VIIRS/SNPP Deep Blue Level 3 monthly 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 temporal aggregation of the daily Level 3 VIIRS Deep Blue product (AERSDB_D3_VIIRS_SNPP) over a period of one calendar month, thus gaps in the aerosol data will appear wherever that does not provide data (e.g. persistent clouds, snow/ice, and polar night)

Production Frequency:
1 file per Month

Spatial Coverage:
Global (daytime only)

Spatial Resolution:
1 degree latitude by 1 degree longitude

File Size:
Variable, but typically 3-6 MB
