Method, device and terminal for generating meteorological satellite data sets

Abstract

The application provides a meteorological satellite data set generation method, device and terminal equipment, which can improve the cloud block recognition accuracy and help simulate the clear sky low temperature condition after night radiation cooling. The meteorological satellite data set generation method comprises the following steps: calculating the cloud cover of each historical meteorological satellite data set through cloud grid points; the historical meteorological satellite data set is historical infrared data, historical visible light data and historical vertical temperature distribution data in the same observation time period of the same observation region; the cloud cover is evenly divided into a plurality of cloud cover intervals, and cloud cover distribution data is obtained according to the cloud cover intervals; the same number of data samples are extracted from each cloud cover interval to generate a meteorological satellite data set; and the daytime clear sky area brightness temperature in the meteorological satellite data set is adjusted downward to simulate the clear sky low temperature condition after night radiation cooling.
