Abstract

Software used for estimating reference evapotranspiration (ET"0) has been developing in various directions. The main goal of this paper is to present an approach based on Service-Oriented Architecture (SOA) paradigm for modeling and estimating ET"0. The FAO-56 Penman-Monteith (FAO-56 PM) and Hargreaves equation are used for estimating monthly ET"0. The weather data for this study were obtained from CIMIS for Davis weather station. The FAO-56 PM and Hargreaves ET"0 values estimated using ET Web service were compared to corresponding CIMIS PM ET"0 estimates. The proposed model based on Web services implemented to the FAO-56 PM and Hargreaves equations has good performances and can be used in estimating ET"0 and has ability to complete missing weather data.
