Disclaimer:
===============================================================================

NOTE: Not all GEOS-Chem revisions are designated as "public" releases. It is 
often expedient to stretch out updates to the code over several "internal" 
versions, so that each individual version may be independently benchmarked. 

You may download the latest internal GEOS-Chem version here; however, please 
be aware that each internal release comes "as-is". Also, the documentation 
(e.g. GEOS-Chem User's Guide) is not updated for internal releases, but only 
for public releases.
