Evapotranspiration data at Starkey pasture site, Pasco County, Florida, January 2010 - April 2016


Publication Date


Swancar, Amy, 2017, Evapotranspiration data at Starkey pasture site, Pasco County, Florida, January 2010 - April 2016: U.S. Geological Survey data release,


This U.S. Geological Survey (USGS) data release consists of evapotranspiration measurements made at the USGS Starkey pasture climate station beginning January 1, 2010 and ending April 30, 2016. Annual ET rates corrected to a near-surface energy-budget for the 12 calendar years of record at this site (2004-2015) varied from 718 mm (2007) to 903 mm (2010). The eddy-covariance method was used, with high-frequency sensors installed above the pasture to measure sensible and latent heat fluxes. Ancillary meteorological data are also included in the data set: net radiation, soil temperature and moisture, air temperature, relative humidity, wind speed and direction, rainfall, and ground-water levels. Data were collected at 30-minute resolution, [...]

Data were collected to quantify evapotranspiration over a representative land cover (unimproved pasture) in west-central Florida. Evapotranspiration is a large but not-well quantified component of local and regional water budgets. Water budgets and models that use this improved estimate of evapotranspiration should provide more accurate predictions of effects on water resources attributable to changes in water use, land use, normal climate cycles, and long-term climate change.
