Abstract

The invention discloses an all-weather surface temperature inversion method and system, and the method comprises the steps: obtaining surface temperature-related data which comprises thermal infraredsurface temperature data, passive microwave data, surface temperature reanalysis data, a normalized vegetation index, and digital elevation model data; if the passive microwave data has a value, predicting the surface temperature based on a random forest model; and if the passive microwave data is missing, predicting the surface temperature based on the temperature annual cycle model. According tothe technical scheme, the problem of inaccurate surface temperature inversion data caused by passive microwave data loss of the surface temperature is solved, and the all-weather surface temperaturecan be efficiently and accurately predicted.

Description

technical field [0001] The present invention relates to the field of remote sensing data analysis and processing, in particular, to an all-weather surface temperature retrieval method and system, and more specifically, to an all-weather model based on a random forest model and an annual temperature cycle model (RF-ATC) Method and system for inversion of land surface temperature. Background technique [0002] Land surface temperature (LST) is the thermodynamic surface temperature of the land surface obtained through remote sensing technology, which is closely related to the surface energy budget and water balance of the Earth system. Among them, all-weather surface temperature has been widely used in many research fields such as climate change, agricultural monitoring, urban heat island, fire detection, public health and environmental issues because of its ability to fully describe temperature changes. Due to the temporal and spatial variation of solar radiation, the instabi...
