On this page we list the current priorities for GEOS-Chem development. This list was compiled by the user Working Groups at the last [http://acmg.seas.harvard.edu/geos/meetings/2015/index.html International GEOS-Chem Meeting (IGC7)] in May 2015 and has been continuously updated since based on code readiness and input from the Working Groups and the Steering Committee.

On this page we list the current priorities for GEOS-Chem development. This list is continuously updated based on code readiness and input from the [https://geos-chem.seas.harvard.edu/geos-working-groups Working Groups] and the [https://geos-chem.seas.harvard.edu/geos-steering-cmte Steering Committee]. For history of past releases see the [[GEOS-Chem_versions|GEOS-Chem Versions wiki page]].
  
We also invite you to view our [https://trello.com/board/geos-chem-support-team/4fe36668fc79a1d3540ba80b GEOS-Chem Support Team project management board on Trello.com], which shows the current GCST workflow.

== Merged and awaiting release ==
  
== List of priorities as of Oct 2016 ==

See the links below for items merged and awaiting release.
  
Items "Awaiting release" will be part of the next version release of GEOS-Chem and are actively being incorporated into the standard model and benchmarked. Other items are in different stages of readiness and will be included in future versions of the model.

Features listed in this table are actively being integrated into GEOS-Chem by the [https://geoschem.github.io/support-team.html GEOS-Chem Support Team]. In addition, we continuously implement structural updates in the model to maintain and develop coupling with other models including GEOS, CESM, and the model adjoint.

:I've incorporated both the metal catalyzed chemistry and the sulfate isotopes into v10. The metal catalyzed chemistry is much slower than it is when run in v8 and v9. I still have not yet figured out why. I'm not comfortable adding this into the standard model until I figure it out. The emissions are quite different in v10 because of HEMCO, and metal catalyzed chemistry is very sensitive to emissions of primary anthropogenic sulfate, so that's my current hypothesis for the difference. I will probably not get back to debugging this until late October.

:I don't think my fix for this issue is ready for prime time. I get chimneys of essentially unscavenged SO2 extending into the UTLS during Asian monsoon, leading to too much sulfate aloft. I think replacing the instantaneous titration of H2O2 in the standard code with the correct oxidation of SO2 by H2O2 (and O3?) is necessary.
