Difference between revisions of "GEOS-Chem model development priorities"

On this page we list the priorities for ongoing GEOS-Chem model development. We also list the items that were once identified as priorities but have since been added to the standard mainline GEOS-Chem code.

== List of priorities as of Dec 2011 ==

Development priorities for GEOS-Chem are identified by users at the biennial users' meetings and updated betweeen meetings by the GEOS-Chem Working Groups and the Steering Committee. They are then incorporated into new GEOS-Chem versions on the basis of readiness and importance. All scientific developments originate from users and readiness is generally measured by the maturity of the product (often a submitted paper) and work by the developer with the GEOS-Chem Support Team to import it into the standard model. Deciding which updates should go into the next version of GEOS-Chem is a responsibility of the GEOS-Chem Steering Committee but user input is eagerly sought.  

On this page we list the model development priorities as "ready to go in", "almost there (<6 months)"

== List of priorities identified at IGC5 ==

This is a list of planned GEOS-Chem model development items, based on discussions and Working Group reports from the  and [http://acmg.seas.harvard.edu/geos/geos_meeting_2011.html 5th International GEOS-Chem Meeting] (aka '''IGC5''').  The key model developer or model contact is identified for each item. 

We count on user input to augment and prioritize this list, please contact your [http://acmg.seas.harvard.edu/geos/geos_working_groups.html Working Group Chair] or model scientist [mailto:djacob@fas.harvard.edu Daniel Jacob].

== Items that are now included in GEOS-Chem ==  

Here we list new features that have since been brought into the standard mainline GEOS-Chem code.  Each of these was identified as a priority at the [http://acmg.seas.harvard.edu/geos/geos_meeting_2011.html 5th International GEOS-Chem Meeting] in 2011 (aka '''IGC5''').
