This U.S. Geological Survey (USGS) data release consists of daily evapotranspiration (ET) measurements/estimates for the time period January 1, 1998 to December 31, 1999. These data are derived from measurements of actual ET conducted at a height of 36.5 meters on a communications-type tower in Tiger Bay State Forest. The station is located at a nearly flat site (29 degrees 8 minutes 15 seconds North / 081 degrees 11 minutes 18 seconds West) within Volusia County, Florida. The surrounding landscape is composed of a mixture of slash pine and pond cypress. A forest fire burned parts of the landscape on June 25, 1998. Logging of fire-damaged trees occurred in November-December 1998. Actual ET measurements were derived using the eddy-covariance method. Funding by the County of Volusia and St. Johns River Water Management District is acknowledged.
