Summary
This U.S. Geological Survey (USGS) data release consists of evapotranspiration measurements made at the USGS Immokalee row crop climate station beginning September 22, 2008 and ending January 8, 2009. Daily evapotranspiration rates corrected to a near-surface energy-budget varied from 0.1 millimeter (9/28/2008) to 3.3 millimeters (9/24/2008). The eddy-covariance method was used, with high-frequency sensors installed above an experimental field planted in green peppers 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, and ground-water level. Data were collected at 30-minute [...]
Summary
This U.S. Geological Survey (USGS) data release consists of evapotranspiration measurements made at the USGS Immokalee row crop climate station beginning September 22, 2008 and ending January 8, 2009. Daily evapotranspiration rates corrected to a near-surface energy-budget varied from 0.1 millimeter (9/28/2008) to 3.3 millimeters (9/24/2008). The eddy-covariance method was used, with high-frequency sensors installed above an experimental field planted in green peppers 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, and ground-water level. Data were collected at 30-minute resolution, with evapotranspiration corrected to the near-surface energy-budget at that timescale. The study was conducted at an experimental field on the University of Florida Southwest Florida Research and Education Center (SWFREC) in Immokalee, Florida (Latitude 26 27 40 North Longitude 81 26 24 West, in degrees minutes seconds, North American Datum 83, Section 20, Township 46S, Range 29E). The full data release associated with this site consists of: 1. Immokalee row crop evapotranspiration, 30-minute data, from September 22, 2008 through January 8, 2009 (comma delimited text format) 2. Immokalee row crop evapotranspiration, daily data, from September 23, 2008 through January 7, 2009 (comma delimited text format) including an ancillary file: Vegetation and equipment photographs (zipped jpeg files).

Purpose
Data were collected to quantify evapotranspiration over a representative land cover (row crop) in south-central Florida. Evapotranspiration (ET) is a large but not-well quantified component of local and regional water budgets. Data were also collected at this site to provide comparison between the eddy-covariance method and the drainage lysimeter method.
