Implementation notes

As of Jan 27, 2010, ISORROPIA II is currently being implemented into GEOS-Chem v8-02-05 (version in testing).

Code structure

The main-level Code directory has now been divided into several subdirectories:

GeosCore/    GEOS-Chem "core" routines
GeosTomas/   Parallel copies of GEOS-Chem routines that reference TOMAS
GeosUtil/    "Utility" modules (e.g. error_mod.f, file_mod.f, time_mod.f, etc.
Headers/     Header files (define.h, CMN_SIZE, CMN_DIAG, etc.)
ISOROPIA/    Directory where ISORROPIA II code resides   
KPP/         KPP solver directory structure
bin/         Directory where executables are placed
doc/         Directory where documentation is created
help/        Directory for GEOS-Chem Help Screen
lib/         Directory where library files are placed
mod/         Directory where module files are placed
obsolete/    Directory where obsolete versions of code are archived

ISORROPIA II consists of the following files:

Files in ISORROPIA/ subdirectory:
---------------------------------
Makefile            Makefile for ISORROPIA II code
isoropiaIIcode.f    Source code file with ISORROPIA II routines
isrpia.inc          Header file with common blocks

Files in GeosCore/ subdirectory:
--------------------------------
isoropiaII_mod.f    "Interface" code between GEOS-Chem and ISORROPIA II
