Method and system for generating hour-by-hour seamless surface temperature

The invention relates to the field of surface temperature products, in particular to an hour-by-hour seamless surface temperature generation method and system. According to the method, the AHI surface temperature is inverted by adopting a temperature emissivity separation algorithm based on the radiance of the AHI thermal infrared band; by taking the inverted AHI surface temperature as a reference, performing deviation correction on the CLDAS surface temperature so as to eliminate system errors of the CLDAS surface temperature; the AHI surface temperature and the CLDAS surface temperature after deviation correction are fused through multi-scale Kalman filtering to generate seamless hourly surface temperature, and the precision of the CLDAS surface temperature is improved. The method has practicability and universality in the aspect of generating hour-by-hour seamless surface temperature products. The invention aims to provide the hour-by-hour seamless surface temperature generation method and system which can
