To accurately provide a basis for the use of solar energy in mainland China, the optimized empirical model is adopted to analyze the variation trends and …

Solar Radiation Climatology Calculation in China

The Angstrom-Prescott formula is commonly used in climatological calculation methods of solar radiation simulation. Fitting the coefficients is carried out using linear regression and in recent years it has been found that these coefficients have obvious spatial variability. A common solution is to divide the study area into several subregions and fit the coefficients …
