trying to understand the physics data structure...

[pkelly]

Since the physics grid stores horizontal data in an arbitrary number of columns or chunks, how can I know the corresponding lat and lon coordinates of each chunk?

I am trying to better understand how momentum tendencies are converted from the physics grid to the dynamics grid.

Thanks for any insight.

The phys_grid module contains the methods get_rlat_all_p and get_rlon_all_p which respectively return the latitudes and longitudes for all columns in a chunk.
