Evapotranspiration (ET) at Lake Wales Ridge site, 20-minute data, Orange County, Florida, September 15, 1993 - August 27, 1994

This U.S. Geological Survey (USGS) data release consists of 20-minute evapotranspiration (ET) measurements/estimates for the time period September 15, 1993 to August 27, 1994. These data are derived from measurements of actual ET conducted at a site within the Lake Wales Ridge, Florida characterized by sandy, rapidly-drained soils, and hilly topography. The station is located at a site (28 degrees 29 minutes 12 seconds North / 081 degrees 38 minutes 19 seconds West) within Orange County, Florida. The surrounding landscape is vegetated by natal grass, dog fennel, dwarf horseweed, and ragweed. The water table is generally more than a meter below land surface. Actual ET measurements were derived using the eddy-covariance method. Funding by the St. Johns River Water Management District is acknowledged.

本美国地质调查局（U.S. Geological Survey, USGS）发布的数据集包含1993年9月15日至1994年8月27日期间的20分钟间隔蒸散发（evapotranspiration, ET）实测值与估算值。该数据集源自美国佛罗里达州威尔士湖脊（Lake Wales Ridge）某站点的实际蒸散发实测工作，该站点区域以沙质、快速排水土壤及丘陵地形为特征。该监测站坐落于佛罗里达州奥兰治县境内，具体坐标为北纬28°29′12″、西经81°38′19″。站点周边植被包括纳塔尔草、狗茴香、矮小飞蓬与豚草。地下水位通常距地表深度超过1米。本次实际蒸散发的实测数据采用涡度协方差法（eddy-covariance method）计算得到。本研究得到圣约翰斯河水资源管理区（St. Johns River Water Management District）的经费资助，特此致谢。
