On this page we list the current priorities for GEOS-Chem development. This list was compiled by the user Working Groups at the last International GEOS-Chem Meeting (IGC5) in May 2011 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]].

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.

== Feature integration in progress ==
  
−
=== Ready to go in ===
+
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.

:We developed and tested the two components in v8.3.1-2. So far we have not got a chance yet to move them into v9.1.2. In the last couple of weeks we began to look into v9.1.2, focusing on re-evaluation of  APM  driven by MERRA data. The 3-hr MERRA data will enable us to get rid of met data interpretation used in APM. After We validate the APM in v9.1.2, we will begin to integrate RF codes and APM capability for nested grid into v9.1.2.

:By now we have done EDGAR 4, and now we are tackling the VOC speciation issue.  Then the next step is to incorporate several regional inventory datasets. My expertise is anthropogenic emission inventory development, so my efforts focus on how to include state-of-art research inventories in the GC model.  I hope we can merge our efforts [with your efforts toward the [[Grid-independent GEOS-Chem#Emissions Component|Grid-independent Emissions Component]]] into one framework.

*Towards this end, we have added the [[Centralized chemistry time step]] option into [[GEOS-Chem v9-01-02]].  This makes sure that the tracer concentrations being sent into the chemistry solver are more representative of the center of the chemistry timestep, and thus are more consistent with when the photolysis gets computed.

*Development of the [[Grid-independent GEOS-Chem#Emissions Component|Emissions Component]] will be the focus of Year 2 of the project.  Much of this work will be done by Christoph Keller (Harvard).  Our goal is to completely replace GEOS-Chem's legacy emissions routines with a modern emissions package that can be easily interfaced to an external GCM.

:I am presently working on publishing this work and this is my last step before graduating with PhD. I will have little time to work on getting this code ready for full implementation. This is due to the fact I have my code in an older version of the model and the newer versions of GEOS-Chem do not even use the same chemical solver and aerosol thermodynamics solver.  So it would be alot of work to get the model ready right now.
