Evapotranspiration Data within Blue Cypress Marsh, Vero Beach, Florida, 2021

The dataset includes a table in comma delimited format of daily evapotranspiration (ET) from 1/1/2021 to 12/31/2021 from an ET station within the Blue Cypress Marsh Conservation Area, near Vero Beach, Florida. Evapotranspiration was estimated using eddy-covariance methods and missing sub-daily (30-minute) and daily ET records were gap-filled with a version of the Turc equation (Trajkovic and Kolakovic, 2009) that was regressed against observed values of eddy-covariance ET. The Turc equation performed well (r-squared value of 0.94 and 0.63 for daily and 30-minute values, respectively) for reproducing observed daily ET rates. Daily ET values estimated with the Turc equation are identified by a column with a "T" value indicator. Data processing methods were similar to methods outlined by Shoemaker and others (2011). Ancillary data includes net radiation, relative humidity, air temperature, soil temperature, water depth above land surface (+) or depth to water below land surface (-). The site location is 27°41'46", -80°42'43". Released data include evapotranspiration (ET, in millimeters per day), net radiation (Rn, in watts per square meter), minimum and maximum daily relative humidity and air temperature (RH_max, RH_min in percent; AT_max, AT_min in degrees Celsius), water distance above (+) and below (-) land surface (WD, in meters), mean daily soil temperature (Ts, in Celsius), and evapotranspiration (ET, in millimeters per day). These data provide updates to prior releases of evapotranspiration data from this station extending back to June 1, 1995.
