The Effect of Meteorological Parameters on Solar Radiation in Babylon

Abstract

Meteorological parameters like monthly mean global solar radiation, monthly average daily sunshine duration, monthly average of the daily temperature, monthly average of the daily relative humidity, difference of maximum to minimum daily temperature and difference of maximum to minimum daily relative humidity was measure from the meteorological station of the (University of Babylon/College of Education for Pure Sciences /Department of Physics) during the period from August 2012 to June 2013.

Eight model's were developed for the location of the station to predict the calculated monthly mean global solar radiation and compare it with the observed value.

A good argument with model five where the value of the mean bias error (MBE) is (0.1852) , t-statistic was the smallest at (0.121) , correlation coefficient (r) value of (0.9125) and the correlation determination with the value of (0.8325).
