Evapotranspiration at the Clewiston Marsh Platform, Lake Okeechobee, Florida, June 15, 2017 - January 21, 2020

Metadata Updated: October 29, 2023

The dataset includes a table in comma delimited format of daily evapotranspiration (ET) from 6/15/2017 to 1/21/2020 from an ET station in wetlands along the western perimeter of Lake Okeechobee, near Clewiston, Florida. The dominant plant cover at the study site is sawgrass (Cladium jamaicense) with secondary amounts of cattails and open water surfaces such as canals for boat navigation. Sawgrass and cattail height generally varies from less than 1 to 2.4 meters. The depth of water in the wetland averages less than 1 meter above land surface but exceeds 1.5 meters when water levels are high in Lake Okeechobee. In contrast, water levels were less than 1 meter below land surface in the wetland from May to June of 2019. Evapotranspiration was estimated using eddy-covariance methods and missing records were gap-filled with the Priestley-Taylor (PT) equation (Priestley and Taylor, 1972) that was regressed against observed daily values of eddy-covariance ET. A constant value of 1.22374 was estimated by regression for the alpha coefficient in the PT equation to minimize residuals. Data processing methods were similar to methods outlined by Shoemaker and others (2011). Ancillary data includes net radiation, relative humidity, air temperature, and lake water temperature.
