Revision as of 13:57, 5 October 2012

NOTE: In light of our new benchmarking procedure instituted at IGC5, every GEOS-Chem version released to the user community is now a public release, in the sense that we run a 1-year benchmark before making the code available. The 1-month benchmarks now replace what we used to call "beta releases". This allows us to retire the last two numbers in the version name. We shall henceforth denote GEOS-Chem versions as GEOS-Chem v9-02, etc. instead of using the previous nomenclature (e.g. GEOS-Chem v9-01-03).

Overview

What's new in this version

NOTE: List under construction

GEOS-Chem v9-02 shall contain the following major updates and improvements. The order has been determined by the GEOS-Chem Steering Committee. We will also continue to add source code updates for the Grid-independent GEOS-Chem project at regular intervals.

New data directories

The following new data directories have been added for GEOS-Chem v9-02. You will have to download the directories relevant to your simulation.

You can download these directories with anonymous FTP or the Wget utility. For instructions, please see Chapter 2.4, Downloading the GEOS-Chem shared data directories in the GEOS-Chem Online User's Guide.
