Abstract

The embodiment of the invention provides an earth surface net radiation estimation method and system, electronic equipment and a storage medium, and the method comprises the steps: determining the multi-source data of a to-be-measured region based on the first remote sensing data and reanalysis meteorological data of the to-be-measured region or the second remote sensing data, the reanalysis meteorological data and the downlink short-wave radiation from station actual measurement data, wherein the first remote sensing data comprises downlink short-wave radiation, and the second remote sensingdata does not comprise downlink short-wave radiation; inputting the multi-source data into an earth surface net radiation estimation model to obtain an earth surface net radiation estimation result, output by the earth surface net radiation estimation model, of the to-be-measured area, wherein the surface net radiation estimation model is obtained by training based on sample site actual measurement data, a sample normalized vegetation index and sample reanalysis meteorological data of a sample region, actual measurement data of the sample station comprises sample downlink short-wave radiation,sample surface albedo and sample surface net radiation, and high-precision and high-resolution estimation of the surface net radiation is realized.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a method, system, electronic equipment and storage medium for estimating net radiation on the ground surface. Background technique [0002] Surface net radiation is the most important parameter in surface energy balance, and it is also one of the important parameters for constructing various ecological models. In the context of global climate change, high-quality long-term net radiation data are of great significance for climate change prediction, evapotranspiration estimation, plant growth and development, and ecosystem biomass formation and accumulation. Remote sensing detection technology provides effective means of observation on a global scale, and has always been an important way of inversion of radiation parameters. The resolution of existing remote sensing products including net radiation is generally low (above kilometer level), which is difficult to meet the nee...
