VIIRS/JPSS2 Downward Shortwave Radiation Daily L3 Global 0.05Deg CMG V002
Listed in NASA Earthdata CMR
The NOAA-21 Visible Infrared Imaging Radiometer Suite (VIIRS) Downward Shortwave Radiation (DSR) Level 3 Climate Modeling Grid (CMG) product produced at 0.05 degree pixel resolution at daily intervals.
Description
DSR is the incident solar radiation over land surfaces in the shortwave spectrum (300-4,000 nanometers) and is a significant variable in land surface models (LSMs), receiving increased attention due to its importance for the management and operation of solar energy systems.
The VJ218 algorithm adapts the narrowband look-up table (LUT) approach to estimate DSR. The LUTs consider different types of loadings of aerosols and clouds at a variety of illumination/viewing geometry. The Algorithm Theoretical Basis Document (ATBD) is forthcoming and will provide additional details regarding the methodology used to create the data.

The VJ218C1 product is aggregated from VJ218A1 files and includes one set of global 3-hour DSR variables and one set of daily mean DSR.
