This U.S. Geological Survey (USGS) data release consists of daily evapotranspiration (ET) measurements/estimates for the time period January 29, 2009 to September 27, 2012. These data are derived from measurements of actual ET conducted at a height of 73 meters on the University of Central Florida WUCF 89.9 radio tower. The station is located at a nearly flat site (28 degrees 35 minutes 27 seconds North / 081 degrees 12 minutes 17 seconds West) within Orange County, Florida. The surrounding landscape is composed (2009 Land cover and land use, St. Johns River Water Management District www.sjrwmd.com) of urban (61 percent), non-urban (34 percent) and water (5 percent) within an 8 kilometer radius of the radio tower. Actual ET measurements were derived using the eddy-covariance method. Funding from St. Johns River Water Management District and Southwest Florida Water Management District is acknowledged.
