Evaporation at LZ40 Platform, Lake Okeechobee, Palm Beach County, Florida, November 16, 2012 - December 31, 2019

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, Florida. 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, 2019, including: precipitation, air temperature, relative humidity, wind speed, incoming/outgoing solar radiation, and water temperature at various depths.

采用鲍恩比法（Bowen ratio method）开展逐日蒸发量监测，监测点位为美国地质调查局（USGS）站点LZ40（站点编号：265405080472100）。该平台式监测站点由南佛罗里达水资源管理区（South Florida Water Management District，简称SFWMD）搭建，坐落于佛罗里达州奥基乔比湖的近似中心区域。数据采集工作于2012年11月15日正式启动。所有气象与环境变量的原始采样间隔为30秒，2013年2月7日之前均以30分钟为时间分辨率进行平均处理；2013年2月7日至2019年12月31日期间，平均计算的时间分辨率调整为15分钟。本次监测涵盖的变量包括：降水量、气温、相对湿度、风速、入射/出射太阳辐射，以及不同深度的水温。
