The Calculation and Distribution of Total Radiation in Jiangsu Province

Abstract

The empirical model of climatological calculation has high precision in Jiangsu that has flat terrain and noncomplex atmospheric environment. In this paper, the monthly percentage of sunshine and total solar radiation from 3 solar radiation stations in Nanjing, Lvsi and Huaian in Jiangsu Province and from 7 other stations in surrounding provinces were used to calculate the empirical coefficient a and b by using climatology methods. The empirical coefficient a and b and the monthly total solar radiation of 70 other stations in Jiangsu were obtained using variety of scheme. The result shows that the monthly total solar radiation which was calculated based on a and b from the inverse distance weighted interpolation method has the least error and distribution of solar radiation in Jiangsu was discussed.
