ADCP Ground Anchor Station EA 4

Ground anchor with ADCP measurement (flow, turbidity). A time series with delta t = 5 minutes. NHN depth: 9 m. The anchored ADCPs record a complete vertical velocity profile: VR = flow direction, vm = flow velocity. The recording begins about 2 m above the lake floor and reaches up to about 2 m below the water surface (depending on depth, sometimes more times less). The vertical resolution (deep cell size) is 0.5 or 0.75 m. The time resolution is 5 minutes. These are mean values, i.e. a total of 50 individual measurements have been averaged over the respective period.搭载声学多普勒流速剖面仪（ADCP，Acoustic Doppler Current Profilers）的地面锚定测站，用于流量与浊度测量。该数据集为时间步长Δt=5分钟的时间序列。NHN水深为9米。锚定的ADCP可采集完整的垂向流速剖面数据：其中VR代表流向，vm代表流速。测量起始位置约位于湖床上方2米处，探测上限可达水面下约2米处（具体覆盖范围依实际水深有所调整，有时覆盖范围会略有增减）。垂向分辨率（即测层单元尺寸）为0.5米或0.75米。时间分辨率为5分钟，所有数据均为对应时段的均值，即对该时段内总计50次单次测量结果进行了平均处理。
