Transitioning from MODIS to VIIRS Global Water Reservoir Product

The 8-day (VNP28C2/VJ128C2) and monthly (VNP28C3/VJ128C3) VIIRS global water reservoir (GWR) product data are available in the respective folders. While the SNPP (VNP) data is available from 2012-2021, the JPSS1 (VJ1) data is provided from March 2020 to December 2021. Please note that VIIRS (Collection 2) GWR products for the full mission period of SNPP and JPSS-1 will be launched by NASA later this year and will be operational. Hence, VIIRS GWR data for the full-time period in the future can be downloaded from NASA LPDAAC. More information about the VIIRS GWR products will be provided at https://viirsland.gsfc.nasa.gov/Products/NASA/GWR.html.
