Description
The NOAA-20 (JPSS-1) Visible Infrared Imaging Radiometer Suite (VIIRS) supports a Day-Night Band (DNB) sensor that provides global daily measurements of nocturnal visible and near-infrared (NIR) light that are suitable for Earth system science and applications. The VIIRS DNB's ultra-sensitivity in lowlight conditions generates science-quality nighttime products that manifest substantial improvements in sensor resolution and calibration when compared to previous eras (such as DMSP/OLS). Such improvements allow the VIIRS DNB products to better monitor both the magnitude and signature of nighttime phenomena, and anthropogenic sources of light emissions.
VJ146A2 is the short-name for the daily moonlight- and atmosphere-corrected Nighttime Lights (NTL) product called VIIRS/NOAA-20 Gap-Filled Lunar BRDF-Adjusted Nighttime Lights Daily L3 Global 500m Linear Lat Lon Grid.
