Posted: Fri Aug 14, 2026 10:10 am America/New_York
The Land Processes Distributed Active Archive Center (LP DAAC) has released Visible Infrared Imaging Radiometer Suite (VIIRS) Version 2 Evapotranspiration, Gross Primary Productivity (GPP), and Net Primary Production (NPP) Data Products from the NOAA-21 satellite. Included in these products are variables for evapotranspiration, latent heat flux, gross primary productivity, net photosynthesis, and net primary production.
Users are encouraged to use the gap-filled (GF) products which are generated only at the end of a given year. Forward processing is available for VJ216A2 and VJ217A2 to accommodate users who need more recent data.
