Accessing SE grid corners in CAM physics

[andreasb]

Hi,I am wondering if there is a way to access the grid corners (in spherical coordinates) in CAM physics modules when using the spectral element core. It seems like there is no simple straightforward way to implement this , but I'd appreciate any help that I can get. From what I see, the elements have corners saved in gnomonic and 3D coordinates. So to access them in the physics modules, could I do the following?1. In element_mod, add spherical corners to element_t2. In cube_mod subroutine coordinates_atomic, add call to cart_to_spherical to calculate corners in spherical coordinates3. In dyn_grid, add subroutine analagous to get_horiz_grid_d to get corners
Thanks,Andreas

This is an unusual thing to do since the physics package is designed to be independent of which dycore is used.  Nonetheless, the strategy you outline seems about right.  The dycore is always responsible for knowledge of the grid, and the dyn_grid module contains the methods used by the physics package to get grid information.
