GEOS-Chem model development priorities
This is a list of planned GEOS-Chem model development items, based on discussions and Working Group reports from the 2009 and 2011 International GEOS-Chem Meetings. 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
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 4th International GEOS-Chem Meeting in 2009 (aka IGC4) or the 5th International GEOS-Chem Meeting in 2011 (aka IGC5).

Items that have yet to be included in GEOS-Chem
We are working towards adding each of these new features into future GEOS-Chem releases. Each of these was identified as a priority at the 4th International GEOS-Chem Meeting in 2009 (aka IGC4) or the 5th International GEOS-Chem GEOS-Chem Meeting in 2011 (aka IGC5).
Item | Author(s) | Priority From | Status |
---|---|---|---|
APM aerosol microphysics | Fangqun Yu | IGC4 | Incorporated and validated in GEOS-Chem v9-01-02, awaiting release |
GFED3 biomass burning | Prasad Kasibhatla | IGC4 | Incorporated into GEOS-Chem v9-01-02, awaiting release |
FAA aircraft emissions inventory | Steven Barrett et al | IGC4 | Incorporated and validated in GEOS-Chem v9-01-02, awaiting release |
Anthropogenic VOCs update | Dylan Millet |
IGC4 | The RETRO anthropogenic VOC emissions will be included into GEOS-Chem v9-01-02. |
Updated soil NOx emissions | Randall Martin Rynda Hudman |
IGC4 | Slated for inclusion into GEOS-Chem v9-01-02 or GEOS-Chem v9-01-03 |
Tropospheric bromine chemistry | Justin Parrella | IGC4 | Substantially complete but undergoing further validation. Slated for inclusion into GEOS-Chem v9-01-03. |
