NOAA-20 VIIRS Land Surface Temperature and Emissivity (LST&E) Version 2 swath product provides daily, 6-minute snapshots of land surface temperature and spectral emissivity. The dataset is generated using a physics-based algorithm that simultaneously retrieves LST and emissivity for three thermal infrared bands at a 750-meter spatial resolution. It is designed for continuity with the MODIS Terra and Aqua mission products, employing an ASTER Temperature Emissivity Separation technique with an improved Water Vapor Scaling atmospheric correction.
