Building topography files for GEOS 5 with the NCAR Topography Tool

This procedure will require script files describing the GMAO cubed sphere grid (or whatever grid you are going to).

First obtain the NCAR topography package from Here:

https://github.com/NCAR/Topo/tags/

Upon downloading there are several directories in the source code, the pertinent ones are:

create_netCDF_from_rawdata - this has the GMTED and GTOPO30 30s dataset

bin_to_cube - This bins the 30s high resolution data to the intermediate c3000 cube.

cube_to_target - This bins the c3000 cube to the target grid in the script file containing the grid description
