摘要
利用全国27个气象站1971-2000年太阳辐射观测资料,按照经验公式法、多因子综合法和Prescoff公式法等三种计算方法对太阳总辐射进行了计算,并与实际太阳总辐射观测资料进行了对比分析。结果表明:经验公式法计算误差较小,但系数不易计算;多因子综合法易于计算,但误差相对较大;Prescoff公式法计算结果误差很大,不适用于太阳总辐射的计算。
Using the solar radiation observation data of the national 27 weather station from 1971 to 2000, according to empirical formula, multi-factor synthesis and Prescoff formula, the quantity of general global solar radiation is computed and then the contrastive analysis with the actual global solar radiation observation material is carried on. Result shows that the empirical formula counting error is small, but the coefficient is not easy to calculate; the multi-factor synthesis is easy to calculate, but the error is relatively big; Prescoff formula computed result error is very big, so it is not suitable for global solar radiation computation.
