Actual evapotranspiration (ET a) was measured at 30-min resolution over a 19-month period (September 28, 2000–April 23, 2002) from a nonirrigated pasture site in Florida, USA, using eddy correlation methods. The relative magnitude of measured ET a (about 66% of long-term annual precipitation at the...
