This presentation details the framework in which the GOES solar radiation product was applied. The Priestley-Taylor method was selected as the most appropriate methods for Florida following a comparison of measured and modeled data at 18 eddy flux and Bowen ratio validation sites. The sites were distributed throughout the Florida and represent a variety of land cover types: open water, marshland, grassland/pasture, citrus and forest. A four component method was shown to provide best estimates of net radiation. While a GOES albedo product was identified as a promising approach, it was determined not to be viable for operational purposes. The method is applied using two albedo values determined from the measured values for land (0.149) and for water (0.062) is recommended for use in Florida net radiation calculations. Net radiation approaches were compared using a database from eleven sites in central Florida having two years of 15 minute data measured by Kipp & Zonen CNR1 four channel radiometers.
The final reference ET and potential ET dataset available for the water resource managers in State of Florida Water Management Districts are presented here in a summary format and compared to prior state ET data resources.
