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 identified at IGC5

This is a list of planned GEOS-Chem model development items, based on discussions and Working Group reports from the and 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 Working Group Chair or model scientist Daniel Jacob.
