Short summary
Satellite land surface temperature (LST) data are vital for earth system studies, but current LST products face limitations: the impact of angular effect, lacking coverage under clouds, and the coarse resolution. This study innovatively generated hourly, angular-normalized, all-weather, high-resolution (0.01°) LST data from 2018 to 2023 using FY-4A official data, which support better LST-related studies of earth system science.
