Empirical models for estimating the daily and monthly global solar radiation for Mediterranean and Central Anatolia region of Turkey

Abstract

Climatology and geoengineering studies in literature clearly identify the relationship between solar radiation and global warming. These studies generally try to predict progress in global warming. To do that, it is essential to predict solar radiation rate, which is directly proportional to global warming. By the obtained solar radiation models in present study, researcher will be adequate to estimate solar radiation rate accurately for future prediction analysis. In this study, data imported from measurement stations were used to develop and validate radiation models by using regression and multi-regression models to estimate daily and monthly global solar radiation for Urgup, Karaman, Nigde, Isparta, Iskenderun and Adana regions. The statistical parameters (MBE, MPE, RMSE and R-2) carried out to evaluate the performance of obtained estimation models. In addition, climatic properties of selected regions had been deeply examined to analyse usability of obtained estimation model for other regions where have similar climate characteristics.
