Velocity and temperature data from Lake Geneva (CH), collected during year 2016

Data collected by 4 Acoustic Doppler Current Profilers (ADCPs) in Lake Geneva (Switzerland), during year 2016. The four files include velocity data, vertically averaged using the depth bins with sufficiently good quality, and corresponding frequency spectra. Temperature data recorded by the ADCPs, at the instruments depth, are also provided, as well as their frequency spectra. All files also include the results from a numerical model of the lake hydrodynamics, at the positions of the ADCPs and at overlapping times.

All files are in HDF5 format, and include relevant metadata.

Summary of datasets:

16A, deployed at (517, 137)km (CH1903 coordinates), measured depth range (velocity) 10-70m, deployed on 8 July 2016, recovered on 2 November 2016. ADCP deployed at the bottom, depth of 82m, vertical resolution of 2m.

16B, deployed at (511, 138)km (CH1903 coordinates), measured depth range (velocity) 15-37m, deployed on 8 July 2016, recovered on 29 October 2016. ADCP deployed at the bottom, depth of 45m, vertical resolution of 1m. Data from this ADCP  has a low signal-to-noise ratio for velocity.

16C, deployed at (529, 150)km (CH1903 coordinates), measured depth range (velocity) 15-65m, deployed on 18 July 2016, recovered on 16 December 2016. ADCP deployed at the bottom, depth of 77m, vertical resolution of 2m.

16D, deployed at (554, 139)km (CH1903 coordinates), measured depth range (velocity) 15-85m, deployed on 23 September 2016, recovered on 23 January 2017. ADCP deployed at a depth of 90m, bottom depth of approximately 130m, vertical resolution of 2m.

本数据集包含2016年于瑞士日内瓦湖（Lake Geneva）通过4台声学多普勒流速剖面仪（Acoustic Doppler Current Profilers，ADCP）采集的观测数据。四个数据文件分别包含基于质量合格的深度分层进行垂直平均后的流速数据及其对应频谱，以及ADCP在仪器安装深度处记录的水温数据与对应频谱。所有文件同时附带ADCP站位处、且与观测时段重叠的湖泊水动力数值模拟结果。

所有数据文件均采用HDF5格式存储，并包含完整的相关元数据。
