    • VIIRS/NPP Land Surface Temperature and Emissivity 6-Min L2 Swath 375m NRT

    Metadata Updated: July 16, 2024

    The Near Real Time (NRT) VIIRS Land Surface Temperature and Emissivity 6-Min L2 Swath 375m product with short-name VNP21IMG_NRT, is the same product but at 375m spatial resolution. The VNP21 algorithm is based on the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Temperature Emissivity Separation (TES) algorithm. This algorithm uses full radiative transfer simulations for the atmospheric correction, and an emissivity model based on the variability in the surface radiance data to dynamically retrieve both LST and spectral emissivity at native pixel resolution. Additional details regarding the methodology are available in the Algorithm Theoretical Basis Document (ATBD) at:
