This is a list of planned GEOS-Chem model development items over the next two years, based on discussions and GEOS-Chem Working Group reports from the April 2009 GEOS-Chem Users' Meeting. The key model developer or model contact is identified for each item. Items are listed in rough order of decreasing readiness, although this can quickly change.

We count on user input to augment and prioritize this list, please contact your Working Group Chair or model scientist Daniel Jacob.

Items that are now included in GEOS-Chem

Item Author(s) Completion Date
Improved BL mixing scheme Jintai Lin Now included in GEOS-Chem v8-02-02; released 08 Jun 2009

Code merging session took place June 6-9, 2009 @ Virginia Tech
  • Merged 3 branches of adjoint
  • Forward model now based on v8-02-01 (w/ GEOS-5)
  • Input files cleaned up and standardized
  • New makefiles; code separated into subdirectories
  • New CVS repository @ U. Colorado for code access
  • Some minor cleanup may still be needed (as of June 2009)
