Description
The Near Real Time (NRT) VIIRS Land Surface Temperature and Emissivity 6-Min L2 Swath 375m product with short-name VJ121IMG_NRT, is the same product but at 375m spatial resolution. The VJ121 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:
