Abstract:In order to test new heliograph prototype based on the principle of integrating sphere,this paper gives a curve fitting and comparative analysis of the second data measured by integrating sphere heliograph and two-axis tracking radiation table in three special weather conditions.The sunshine duration measured by integrating sphere heliograph and two-axis tracking radiation table is statistical analyzed.The results show that there are differences of sunshine duration measured by integrating sphere heliograph and two-axis tracking radiation table in different weather conditions.When there are clouds,good visibility in sunny day and stronger solar radiation,the irradiance measured by two-axis tracking radiation table is bigger than the the irradiance measured by integrating sphere heliograph because of the difference of sensitivity.On the whole,there is a good correlation and consistent trend for integrating sphere heliograph and two-axis tracking radiation table from the correlation and statistical analysis.
