Turbulence Data Set

Description

Example Data set with simulated 2hourly turbulence and temperature data for a conic virtual lake.

Format

List with the following elements:

time

vector with time (days)

level

vector with water level above ground (m)

temp

matrix of simulated water temperatures (deg C)

eddy

matrix of simulated eddy diffusivity (m^2/s)

Details

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.
