Özet:

 

A new set of constants for Angstrom-type correlation of  first and second order, to estimate monthly average daily global solar  radiation, has been obtained employing sunshine hours data recorded at  Karachi, Pakistan (Lat.  24° 54' N, Long.  67° 08' E).  Least square  regression is performed to derive these constants.  The correlation  equations developed are employed to calculate the monthly average  daily global solar radiation.  These results are then compared with  various other existing correlations and the measured data.  Excellent  agreement has been found between the estimated and the measured  values.
