ELITE LST: FY-3E/MERSI Clear-Sky LST & E at Dawn and Dusk over CONUS (2023.05-2024.04)

The Essential thermal Infrared remoTe sEnsing (ELITE) product suite currently has four types of products, including land surface temperature (LST: clear-sky and all-sky), emissivity (NBE: narrowband emissivity; BBE: broadband emissivity; and spectral emissivity), the component of surface radiation and energy budget (SLUR: surface longwave upwelling radiation; SLDR: surface longwave downward radiation SLDR; SLNR: surface longwave net radiation), and the component of Earth’s radiation budget (OLR; outgoing longwave radiation; RSR: reflected solar radiation). The spatial-temporal resolutions of the ELITE products are mainly determined by the employed satellite data sources. For more information about ELITE products, please refer to the website (https://elite.bnu.edu.cn). This dataset provides the FY-3E/MERSI clear-sky LST & E at dawn and dusk over CONUS (SURFRAD network) from May 2023 to April 2024. It is derived from FY-3E/MERSI 1 km swath data. Each scene is stored as a GeoTIFF file named FY3E_MERSI_LSTE_YYYYMMDD_hhmm.tif, with 4 bands representing: LST, LSE@8.55μm, LSE@10.8μm, LSE@12.0μm. During validation, a small number of anomalously low values were identified, suggesting that some cloud-contaminated pixels were not effectively filtered by the FY-3E/MERSI CLM product. Users are advised to check the LSE values at 10.8 μm and 12 μm. If both bands have LSE values lower than 0.95, the pixel may be cloud-contaminated.
