利用遥感卫星产品和数值预报产品建立短波辐射反演模型的原理，得出模型中各参数的计算方法。通过反演模型计算出浙江省境内3个辐射站各季节1个代表月中10:00—16:00每个整点时刻的短波辐射，并结合3个辐射站的同期短波辐射实测值建立订正模型。运用订正模型和残差修正，计算出浙江省全境2020年10月1日15时的短波辐射。结果表明，利用卫星产品和数值预报产品建立的短波辐射反演模型计算出的结果与实测值具有较好的线性关系，且该关系在同一季节的代表月中在不同站点具有相同的特征。各站通过数据混合建立的各季代表月的订正模型误差较小，可以用于整点短波辐射的计算，为精细化的农业气候资源区划、太阳能评估等提供新的思路。
Abstract：The principle of short-wave radiation inversion model which based on the remote sensing data and numerical weather forecast products were expatiated systematically, and the calculation method of each parameter in the model was given.By the model, the shortwave radiation at 3 stations in Zhejiang province on every hour from 10:00—16:00 in each typical month of seasons were calculated.Combined with the measured data, corrected model was created.Using the inversion model and corrected model, the shortwave radiation distribution map of Zhejiang at 15:00 on October 1,2020 was generated. These results suggest that there are good linear relationship between the calculations and those of direct measurements. However, the relationship in the same month at different locations has the same or similar characteristics. The correcting model created from the data of different locations in a month will produce the results without much deviation. These can be used for calculating the instantaneous shortwave radiation intensity, which could provide a new approach for agro-meteorological resources regionalization and solar energy assessment.
