Suitability evaluationand parameter optimization of radiation model in Huanghuai Region

Based on the solar radiation and meteorology data of eight radiation sites from 1961 to 2015 in Huanghuai Region, the applicability of six common global solar radiation and surface effective radiation model was evaluated respectively, and multiple regression analysis and iteration method were used toestablished the radiation optimization estimation model suited for Huanghuai Region through the optimization adjustment of radiation parameter. Results show that TONG Hongliang and DENG Genyun formula have the minimum error on estimatin of global solar radiation and surface effective radiation respectively, so compared to the rest of the radiation estimation model, They formula have the best applicability in Huanghuai Region. In addition, the Absolutevalue ofRelative Error (ARE) value and the Root Mean Square Error(RMSE) value on the localized correction model of global solar radiation are 16.28% and 1.730 MJ·m^-2·d^-1 respectively, better than common estimation model of global solar radiation such as TONG Hongliang formula, etc. The REA value and the root mean square error value on the localized correction model of surface effective radiation are 23.19% and 1.404 MJ·m^-2·d^-1 respectively, better than common estimation model of surface effective radiation such as DENG Genyun formula, etc. So the localized radiation correction model in HuanghuaiRegion is suitable for the local surface net radiation estimating, also has good estimation accuracy.
