天津市太阳辐射能资源的精细估算研究

A STUDY OF THE METICULOUS ESTIMATION OF THE SOLARRADIATION ENERGY RESOURCE IN TIANJIN

本文根据天津市区１９５９～１９９４年共计３６ａ逐日实测总辐射资料，建立了用其它气象要素（日照百分率及空气湿度）估算不同尺度（年、季、月、旬、候及逐日）太阳总辐射量的系列经验公式，其平均拟合精确度可达９０％～９７％。

n this paper, on the basis of the daily observational data of total solar radiation of 36 years ( from 1959 to 1994 ) in Tianjin city, we set up a series of empirical formulas,by which the total solar radiaiton of different time scales ( year, season, month, dekad, pentad and day ) can be estimated through using other meteorological elements ( percentage of sunshine, and air humidity ). The mean fitting degree may reach the accuracy of 90 to 97 percent.
