Abstract: |
Long term storage of data from 6 synoptic stations obtained from Meteorological Organization of Iran was used to study the trends in sunshine hours in Kurdistan. At the beginning, the regions were distinguished in an Arc GIS environment to define the radiation zones. Then the trend in sunshine hours in Kurdistan was studied using Mann-Kendall analysis. The obtained results showed that the trend was positive in all six studied stations. But such changes reached more than 4 hours in a year in stations including Sanandaj and Saghez. Finally, the point data were mapped using the potentials of Arc GIS software to give a better presentation of areas with the increasing trend of the parameter in the province. |
