The study was conducted to know the appropriate probability distribution for weekly reference crop evapotranspiration (ETr) values at desired probability levels for Solapur, Ahmednagar, Pune and Nasik stations of Maharashtra, India. ETr values were estimated by Penman-Monteith, Modified Penman, Hargreaves-Samani, Pan Evaporation, Blanney-Criddle, and Radiation methods. Based on the root mean square error, Hargraves-Samani found to be the best method for Solapur and Nasik stations and Modified Penman for Ahmednagar and Pune stations. The probability distribution functions selected were...
