GLM Setup and Configuration
Running GLM
GLM is run from the directory containing glm3.nml:
cd /path/to/sim && glm
Key NML Sections
&glm_setup: Layer configuration&light: Light attenuation (Kw= light extinction coefficient)&mixing: Mixing parameters (coef_mix_hyp= hypolimnetic mixing)&meteorology: Met forcing adjustments (wind_factor,sw_factor,lw_factor,cd,ce,ch)&time: Simulation period (start,stop,dt)&output: Output directory and file naming&init_profiles: Initial temperature/salinity profiles&morphometry: Lake bathymetry&inflow/&outflow: Hydrological boundary conditions
Output
- NetCDF file at
<out_dir>/<out_fn>.nc - Contains variables:
temp(temperature),salt, etc. - Dimensions: time × depth (layers vary per timestep)
zvariable gives height above bottom; convert to depth = lake_depth - z
NML Editing
Fortran namelist format. Parameters are key = value pairs within §ion ... / blocks.
