This page explains how to checkout the code and what is included.

Checking out the code

The source code is available by combining the trunks of two EMC repositories, one for NEMS and one for GFS. The code can be checked out by typing the following lines:

svn checkout https://svnemc.ncep.noaa.gov/projects/nems/trunk PhysDrvI
cd PhysDrvI/src/atmos
svn checkout https://svnemc.ncep.noaa.gov/projects/gsm/trunk gsm

Directory Structure

Once you have obtained the code, you will have the following directory structure within the PhysDrvI directory (only relevant directories and files are listed here).

src/atmos/phys/
- nuopc_physics.F90 ... physics driver, DDTs, wrapper subroutines
- grrad.f ... radiation subroutine
- gbphys.f ... non-radiation physics subroutine
src/atmos/gsm/phys
- gfs_physics_initialize_mod.f ... calls nuopc_phys_init()
- gfs_physics_run_mod.f ... calls do_physics_one_step, passes mdl_param from init
- do_physics_one_step.f ... cals gloopr and gloopb, passes mdl_param
- gloopr.f ... fills the DDT containers and calls nuopc_rad_run
- gloopb.f ... fills the DDT containers and calls nuopc_phys_run
- gfs_physics_internal_state_mod.f ... defines the gfs physics internal state
