ELITE land surface temperature: FY-4B/AGRI hourly 4km clear-sky LST (2022.6-2023.12)

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 is the 4km hourly clear-sky LST dataset derived by the iTES algorithm  from the FY-4B/AGRI thermal infrared data, covering the AGRI 4km nominal fixed disc (80.6°N-80.6°S, 51.8°E-145.8°W). The temporal resolution and spatial resolution of this dataset are one hour and 4km, respectively.

This is the ELITE FY-4B/AGRI clear-sky LST product in 2022.6-2023.12.
