I was wondering if you knew why these exact numbers were chosen.

This is the number of points in the grid at /net/sampo/data1/wxquest_data/coupler_grids/zg_3h_inst_helem_32_zelem_63_output_at_levels_true.nc, which was originally used to generate the initial condition files.

This PR updates the wxquest_initial_conditions artifact.
Previously the atmosphere grid file was assumed to exist at a hardcoded /net/sampo path. Now we generate it programmatically from equispaced lon/lat (linspace -180:180 x384, -90:90 x192, verified against the original file on sampo), download ERA5 at model levels, and pass the grid file explicitly to preprocessing.jl.
