Evaporation at LZ40 Platform, Lake Okeechobee, Palm Beach County, Florida, 2016

Daily measurements of evaporation using the Bowen ratio method were made at USGS station name LZ40 (USGS site number 265405080472100), a platform-based station constructed by the South Florida Water Management District (SFWMD) at the approximate center of Lake Okeechobee. Data collection began on November 15, 2012. Meteorological and environmental variables were measured every 30 seconds and averaged at 30-minute resolution until February 7, 2013 and 15-minute resolution thereafter to December 31, 2016, including: precipitation, air temperature, relative humidity, wind speed, net radiation, incoming solar radiation, and water temperature at various depths. The SFWMD also maintains meteorological and stage measurement equipment on the platform, and lake stage and precipitation were downloaded from the SFWMD web site DBHYDRO for use in the attached spreadsheet.
