Abstract: Abstract The RadEst 3.00 version software estimates total solar radiation using meteorological parameters such as precipitation, temperatures and solar radiation of Jumla (Lat. 29.27°N, Lon. 82.18°E, and Alt. 2514 m). The average temperature in Jumla varies between 12 to 30 °C and −11 to 12 °C at summer and winter respectively. The annual average precipitation is about 667–852 mm.The annual average daily global solar radiation is about 18.28 MJ/m2/day which is greater than at mid hill and low land region of Nepal. Radiation is calculated as the product of the atmospheric transmissivity of radiation and radiation outside earth atmosphere. The model parameters are fitted in two years data. The values estimated by the models are compared with measured solar radiation data. The performance of the model was evaluated using root mean square error (RMSE), mean bias error (MBE), Coefficient of Residual Mass (CRM) and coefficient of determination (R2). The RadEst 3.0 software which showed the better results using BC, CD, DB and DCBB, among them the BC model is the best model for this site. The values of RMSE, MBE, CRM and R2 are 2.16, 1.64, 0.00 and 0.79 respectively. The finding coefficients of these models can be utilized for the estimation of solar radiation at the similar meteorological sites of Nepal. The result confirms that there is strong correlation of global solar radiation with altitude and local weather condition.
