Abstract

One of the basic requirements in research on agriculture and natural resources is climatic data. Most of basins in Iran have not any weather station and because of insufficient data and short observed records, the estimation of data for larger area is difficult. Moreover, most times one or more methods are selected regardless of considering other methods. The application of interpolation methods for estimation meteorological data has not been widely used in Iran. In this research, the three following methods have been used: KRIGING, Weighted moving average (WMA), and Thin plate smoothing splines (TPSS). The results showed that TPSS was showed the most appropriate for estimation of monthly and annual EVAPORATION. Also, The TPSS method showed the most precise results for estimation of both monthly and annual air TEMPERATURE. In addition, the effect of climate scheme on the accuracy of TEMPERATURE and EVAPORATION was investigated. Based on the results, the climate scheme had a positive effect on TEMPERATURE, but no effect on EVAPORATION was observed.
