2.1.1 Directory Hierarchy

Once the source tar-ball is untarred, the directory hierarchy for "CAM2.0" is as follows:
 

Table 2.1:  Directory Hierarchy

Directory name	Synopsis
models/atm/cam/bld/	Scripts to build and execute the model
models/atm/cam/src/	Atmosphere model main source code directory
models/atm/cam/src/advection/slt	SLT advection routines
models/atm/cam/src/control	Control code
models/atm/cam/src/dynamics/eul	Eulerian dynamics
models/atm/cam/src/dynamics/fv	Finite-Volume dynamics
models/atm/cam/src/dynamics/sld	Semi-Lagrangian dynamics
models/atm/cam/src/ocnsice/dom	Data Ocean Model
models/atm/cam/src/physics/cam1	Physics routines (e.g., radiation, convection)
models/atm/cam/src/utils	CAM specific utilities
models/atm/cam/tools/	Directory of tools (such as history compare routines)
models/atm/cam/tools/cprnc	History file comparison program. Normally used to compare code modifications to a "base-line" code. Prints out summary of differences.
models/atmlnd_share	Code shared between the CLM2.0 and CAM
models/csm_share	Code shared by all the geophysical model components of the Community Climate System Model (CCSM)(e.g. code for CCSM message passing and orbital calculations)
models/lnd/clm2	CLM2.0 code
models/ice/csim4	CSIM4 code
models/utils	Independent utility codes
models/utils/esmf	General purpose Earth System Modeling Framework (ESMF) utilities.
