摘要: Abstract Correlation between clearness index and sunshine duration is useful to the estimation of solar radiation for areas where measured data are not available. Regression techniques were used investigate correlations daily global different climates in China. Measurements made during 30-year period (1971–2000) from 40 measuring stations covering major thermal climatic zones across China have been gathered analysed. The developed each individual station as well climates. It was found that Angstrom–Prescott equation tended give a good based on corresponding hours. A simple two-parameter linear regression proposed zones.
