Overview
NOTE: Page under construction
The Linoz stratospheric ozone chemistry package ...
Authors and collaborators:
- Chris McLinden (UC Irvine ?)
- Philip Cameron-Smith (LLNL)
- Brendan Field (formerly Harvard)
- Dylan Jones (U. Toronto)
- Jane Liu (U. Toronto)
Implementation notes
Linoz has been implemented into GEOS-Chem v8-02-04.
Code structure
The main-level Code directory has now been divided into several subdirectories:
GeosCore/ GEOS-Chem "core" routines 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
Linoz consists of the following files:
- GeosCore/linoz_mod.f: Source code file with Linoz chemistry subroutines
- GEOS_1x1/Linoz_200910/Linoz_March2007.dat: File with ozone climatology in the GEOS_1x1 data directory

- I think that it is safe to release [Linoz in v8-02-04]. However, we should acknowledge that it was [only] tested in v8-02-01, since I was not able to assess the quality of the output in v8-02-04.
