Impact model: FLake-DkIT

FLake is a one-dimensional bulk model of the lake thermal regime specifically designed to parameterize inland waters in climate models and numerical weather prediction systems. FLake is based on a two-layer parametric representation of the vertical temperature structure.

Additional questions 1
How did you initialise you lake temperature profile?: Firstly set to 4C throughout, but then altered according to the 2-year spin-up period
How did you set lake depth?: GLDB
How did you set water transparency?: Following empirical relation of extinction coefficient to lake depth by (Hakanson, 1995)
