【摘要】 现行计算水平面太阳日辐射主要有两种方式:一种是利用影响辐射的相关要素建立模型,另一种是依据实测资料进行空间插值。但后一种方法若要保证精度则需有足够多的样本。针对上述问题,利用我国不同区域67个站点的数据,在VP-RAD模型的基础上,建立了一个适用于中国地区的逐日太阳辐射算法CNR,该算法仅需要输入站点基本信息、最高最低温度和降水量。模拟结果与实际观测结果比较吻合。更多还原

【Abstract】 Currently,there are two methods to calculate daily solar radiation on horizontal level,one utilizes the relative element that influence the solar radiance to establish the model,another uses spatial interpolation method that relied on the observed data.However,the latter one needs enough samples to keep high accuracy.In this paper,we developed a new model for China’s daily solar radiation calculation based on VP-RAD model.The model inputs include basic station information(latitude and elevation),daily temperature range and precipitation.The model was developed and validated by the data observed from 67 meteorology stations in different regions of China.The result indicates that this model is reasonable and applicable.更多还原
