Here we present a simple tutorial to build a new topography map that can be used in the Generic PCM.

Surface topography maps are netcdf files stored in your /datagcm/surface_data/ repository. Such files contain information on terrain elevations, as well as albedo and thermal inertia.

As a reminder, our database of surface topography files is available here: https://web.lmd.jussieu.fr/~lmdz/planets/LMDZ.GENERIC/datagcm/surface_data/

Getting topography and surface data

A few options to do that:

You can also derive data files by digitalizing color maps. See below an example:
