【Abstract】 In this paper, new solar radiation modeling based on stepwise regression analysis are put forward for estimating global solar radiation from common climate variables (such as sunshine duration, cloud cover, vapor pressure) and geographical elements (altitude, latitude), which simplify the simulation process, improve the operational efficiency under the similar preci- sion. Based on these models and the observation data of common meteorological elements at more than 730 stations in China, the res... 更多还原
