Topography

The spectral_init_cond_nml only ever needs to be specified if land_option is input in idealized_moist_phys_nml. It contains options which specify the topography of the land. It is described on Isca's website and there is an example script using topography.

The options are described below:

Options

topography_option

string
This indicates how the topography is specified. There are 4 options:

• input - Get topography from input file.
• flat - Surface geopotential is 0 (not widely used).
• interpolated - Not currently used.
• gaussian - Simple Gaussian-shaped mountains are generated from specified parameters (not widely used).

Default: flat

topog_file_name

string
File that contains the topography information.
This should be the same as land_file_name but without INPUT i.e. if the file is called land.nc and is in the input_dir then topog_file_name should be land.nc.
Default: topography.data.nc

topog_field_name

string
The height field name in the input file.
Default: zsurf

land_field_name

string
The land field name in the input file.
This should be the same as land_field_name in the idealized_moist_phys_nml namelist.
Default: land_mask
