NOAA and the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center are collaborating on the development of a Land Product Characterization System (LPCS) that will facilitate the application of multi-satellite and in-situ data for characterization and validation of satellite-derived land-related products (e.g., Surface Reflectance, Normalized Difference Vegetation Index, and Land Surface Temperature). The system is designed to utilize data and products available and anticipated from the Landsat 8, ESA Sentinel-2 and -3 series of satellites, and other relatively high and medium resolution sensors, to validate GOES-16 Advanced Baseline Imager (ABI) and Suomi National Polar-orbiting Partnership (S-NPP)/Joint Polar Satellite System (JPSS) Visible Infrared Imaging Radiometer Suite (VIIRS) products. The LPCS includes data inventory, access, and analysis functions that will permit selection of data to be easily identified, retrieved, co-registered, and compared statistically through a single interface.
