Global solar radiation is considered one of the most important clusters in the world. Today, the use of solar energy as a new energy is one of the fundamental tools for optimal exploitation of global climate-related climatic capabilities. This study aims to calibrate and validate the existing model In order to estimate the amount of radiation of the global sun and the mapping of its zoning maps, it is in the province of Mazandaran. The study used in this study was a field-library. In this research, data from 5 stations of synoptic meteorology of Mazandaran province have been reported daily since the beginning of the year 2000 to January 1, 2010 was used In this study, Angstrom and Prescott solar models were used to calibrate and validate the data of the weather stations of the province. For this purpose, the most important statistical parameters such as equilibrium error (MBE) and least square error (RMSE) and correlation coefficient (r) was used to estimate the radiation and evaluate the accuracy of the estimated data. Finally, the solar energy of the study area was used to generate Atlas maps. Several models were used in this way. ArcGIS9.2 was used in this way. The results showed that according to the solar radiation model, Angstrom and Prescott, the highest radiation was observed in the central and eastern regions of the province It is estimated at 220 to 354 watts per square meter.
