河北省太阳总辐射经验系数两种气候学计算方法的比较分析
Comparison of two methods for determination of empirical coefficients used to estimate total solar radiation in Hebei province
摘要
Abstract
Based on the monthly sunshine percentage and solar radiation data from 8 solar radiation stations sur-rounding Hebei province,the empirical coefficients of a and b in the climatic formula of total solar radiation were calculated by a least-squares method.These coefficients were then obtained for 142 stations in the whole province using methods of a latitude partition and an inverse distance weighted interpolation.The total solar radiations at four solar radiation observational stations were calculated using the above empirical coefficients and the results were compared with the observation.The comparisons have shown that the accuracies of the two methods are simi-lar.However,the annual total solar radiation calculated using the latitude partition method is closer to the observa-tion.Thus,this method is recommended to use for estimating the total solar radiation in Hebei province.关键词
