Turbulence Data Set
Example Data set with simulated 2hourly turbulence and temperature data for a conic virtual lake.
List with the following elements:
vector with time (days)
vector with water level above ground (m)
matrix of simulated water temperatures (deg C)
matrix of simulated eddy diffusivity (m^2/s)
Data were simulated with the General Ocean Turbulence Model (GOTM; Stips et al 2002, Burchardt et al. 2007) for a lake with conic morphometry and then linearly interpolated to equidistant depths. Conductivity was set to zero and is omitted. See Sachse et al. (2014) for further details of the model setup.
