In situations of limited meteorological data, radiation-based potential evapotranspiration (ETp) equations could be used in irrigation scheduling and hydrology due to their minimum data requirements and ease of computation. However, their utilization is limited due to variability in their accuracy and absence of accurate solar radiation data. The objectives of this study were to: 1) select and calibrate radiation-based equations for estimating ETp under Floridas humid subtropical climate and 2) evaluate performance of the calibrated radiation-based equations when applied with Geostationary Operational Environmental Satellite (GOES) derived solar radiation as an alternative to ground-based measurements.(Download PDF) (Export to EndNotes)
