Open water evaporation of Lake IJssel, data used in the study 'Evaporation from a large lowland reservoir – observed dynamics during a warm summer'.

Time series of open water evaporation of Lake IJssel, the Netherlands, during the years 2019 and 2020 at two locations at the border of the lake: Stavoren and Trintelhaven. Data was collected using the eddy covariance instrument of the type IRGASON at a sampling frequency of 20Hz. Data was processed using EddyPro software for a 30-min averaging interval. The measurement height was 7.5 m and 10.8 m in Stavoren and Trintelhaven, respectively. Variables Tair and RH were collected using a separate HMP155A instrument at a height of 7.4 m and 10.9 m above surface in Stavoren and Trintelhaven, respectively. This data belongs to the study 'Evaporation from a large lowland reservoir – observed dynamics during a warm summer'.

本数据集包含荷兰艾瑟尔湖（Lake IJssel）2019至2020年两处湖岸站点的开放水域蒸发量时间序列数据，两处站点分别为斯塔福伦（Stavoren）与特林特尔港（Trintelhaven）。数据采用型号为IRGASON的涡度协方差（eddy covariance）仪器采集，采样频率为20Hz；后续通过EddyPro软件以30分钟为平均间隔完成数据处理。斯塔福伦与特林特尔港站点的测量高度分别为7.5米与10.8米。气温（Tair）与相对湿度（RH）变量通过独立的HMP155A仪器采集，二者在斯塔福伦与特林特尔港站点的安装高度分别为地表以上7.4米与10.9米。本数据集隶属于研究《大型低地水库蒸发——暖夏期间的观测动态》（原英文标题：Evaporation from a large lowland reservoir – observed dynamics during a warm summer）。
