ELITE land surface temperature: FY-4B/AGRI hourly 4km seamless 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 ELITE hourly seamless 4 km LST dataset covering the FY-4B/AGRI nominal fixed disc (80.6°N-80.6°S, 51.8°E-145.8°W).  First, an improved temperature and emissivity separation algorithm was used to obtain the clear-sky LST. Then, under the framework of the SEB theory, a unique way was proposed to solve the temperature difference between the cloudy-sky LST and hypothetical clear-sky LST caused by cloud radiative effects.  The temporal resolution and spatial resolution of this dataset are 1 hour and 4 km, respectively.

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