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年两处湖滨测点的开放水体蒸发量时间序列数据，测点分别为斯塔福伦（Stavoren）与特林特尔港（Trintelhaven）。数据采用型号为IRGASON的涡度协方差仪（eddy covariance instrument）采集，采样频率为20Hz。数据以30分钟为平均间隔，通过EddyPro软件完成处理。两处测点的蒸发量测量高度分别为7.5米（斯塔福伦）与10.8米（特林特尔港）。气温（Tair）与相对湿度（RH）数据由独立的HMP155A仪器采集，斯塔福伦与特林特尔港的该仪器安装高度分别为距地表7.4米与10.9米。本数据集隶属于研究《大型低地水库蒸发量——暖夏期间的观测动态》（Evaporation from a large lowland reservoir – observed dynamics during a warm summer）。
