Simstrat-UoG is a buoyancy-extended k-e model, adapted to specific conditions of an enclosed bassin. Simstrat-UoG is a modified version of Simstrat. The main difference is the ice-snow routine formulation. For global runs, lake specific parameterization was deactivated.
Information for the model SIMSTRAT-UoG is provided for the simulation rounds shown in the tabs below. Click on the appropriate tab to get the information for the simulation round you are interested in.

Was A Spin-Up Performed?: Yes
Spin-Up Design: 30 years of spin-up (year 1661 repeted 30 times) were used to start the picontrol simulations. Historical simulations were started from the picontrol simulations (from 1861) and future simulations were started from historical simulations (thus no spin-up was needed after 1661).
Snow Melt: Ice-snow melt alculated as in Patterson and Hamblin (1988)
Additional questions 1
How did you initialise you lake temperature profile?: Lake temperature profile was initialized with a homogeneous 10°C profile
How did you set lake depth?: Lake depth was based on a regridded Global Lake Data Base (GLDB; Kourzeneva, 2009);
How did you set water transparency?: Following empirical relation of extinction coefficient to lake depth by Hakanson,(1995)
