The study goal to study the relation between the solar radiation and air temperature in the different locations of Kirkuk governorate (Latitude: 35.47°N, Longitude: 44.39°E) (Haweij, Qar enger, Daquq and Alton Copry) from using data of (Solar radiation and air temperature) for the year (2013), was available from the Iraqi Agro meteorology Network / Ministry of Agriculture.
In this study the relationship between Solar radiation and air temperature has been investigated by calculation the correlation coefficient by using program of Microsoft excel (2010), results show strong linear correlation between the monthely and seaseonally sum of solar radiation and the monthely and seaseonally average of air temperature in the four studying locations.
Monthely correlation coefficient between (0.93 – 0.96), in the other hand Seaseonally correlation coefficient between (0.91 – 0.99) in studying locations. This indicates that the increasing in solar radiation leads to increase the values of air temperature, and the decreasing in solar radiation leads to decrease the values of air temperature.
