Abstract

The invention discloses a high-spatial-and-temporal-resolution land surface temperature fusion method based on multi-source satellite data, which is characterized by including the following steps: A,inputting multiple pieces of satellite image data, and preprocessing the satellite image data; B, selecting the preprocessed satellite image data for land surface temperature (LST) inversion; and C, carrying out fusion calculation on the result of LST inversion to get LST data with high spatial and temporal resolution. According to the invention, fusion calculation can be carried out on the imagedata of multiple satellite sensors to get more accurate land surface temperature with high spatial and temporal resolution.

Description

technical field [0001] The invention belongs to the field of satellite remote sensing, and in particular relates to a land surface temperature fusion method with high temporal and spatial resolution based on multi-source satellite data. Background technique [0002] Land Surface Temperature (LST) is a key parameter of land surface system processes on regional and global scales. It integrates the interaction between the surface and the atmosphere and the results of the energy exchange between the atmosphere and the land, and is widely used in surface energy. Research fields such as balance, climate change and resource and environmental monitoring. Timely grasping the temporal and spatial distribution of land surface temperature on the regional and global scales, especially the comprehensive, complete and continuous temporal and spatial distribution of land surface temperature, is of great significance for the study of the energy balance of the earth-atmosphere system and the ...
