Abstract

The aim of the current study in the Central Anatolia Region was on assessing the reference evapotranspiration (ETo) behavior as proxies in exposing the presence of climate variability. Historical climatic data spanning forty-three years (1970-2012) from the Turkish State Meteorological Service was used to calculate ETo data for five meteorological stations. The change–point in ETo dataset was revealed by the distribution-free CUSUM (Cumulative Sum) statistic technique. The two stations, named Ankara and Konya, had a statistically significant shift. None of the others showed significant variability in statistic sense.
