:Recently we have developed a new Asian emission inventory for 2008 and 2010, with 0.25 x 0.25 degree resolution. This inventory is a combination of China inventory from my group, India inventory from David Streets, Korea and Japan inventory from official data, and rest of Asia from REAS data. This inventory will be used for the coming MICS-Asia phase III and HTAP assessment. If the community would like to use the new inventory immediately in GEOS-Chem, we can implement it in couple of weeks.

:While the first paper on aerosol direct radiative forcing (DRF) with the CCCMa RF code has been published (Ma et al., ACP, 2012), a comparison of DRF values (clear sky vs all sky) of GEOS-Chem  with those of others in AeroCom (Myhre et al., ACPD, 2012) indicates that CCCMa RF code may have underestimated the impacts of clouds on radiation... More time is needed for further simulations and evaluations. After I am happy with the RF results and if there is enough interest in the community, I will try to find time to move the APM optical calculation code and RRTMG code into v9.1.3 and handle them to GC support team for inclusion in the standard version.

: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.

*We delivered the [[Grid-Independent GEOS-Chem: Chemistry Component|Chemistry Component]] to NASA/GMAO on June 1, 2012 (at the end of project Year 1).
 
−
*After the initial handoff, it was discovered that further [[Grid-Independent GEOS-Chem: Chemistry Component#Standardization of code that was originally only used with the DEVEL.3Dyes_option|technical fixes]] and [[Grid-Independent GEOS-Chem: Chemistry Component#Additional_modifications_that_are_activated_with_the_DEVEL.3Dyes_option|updates]] were necessary.  We have largely resolved these in [[GEOS-Chem v9-01-03 benchmark history#v9-01-03p|1-month benchmark v9-01-03p]].
 
−
*We are currently testing the GEOS-Chem/GEOS-5 GCM interface on machines at NASA.
 
−
*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.
 
−
*Many modifications to facilitate the GEOS-Chem/GEOS-5 interface were standardized in [[GEOS-Chem v9-01-03]].
 
−
*We are currently testing the GEOS-Chem chemistry and dry deposition routines within the ESMF interface that will be used to connect GEOS-Chem to the GEOS-5 GCM.  [[Grid-Independent GEOS-Chem: Chemistry_Component#Activation of new pathways for data flow and other structural modifications|Many related improvements]] are being added to [[GEOS-Chem v9-02]].
 
−
*Testing of GEOS-Chem within the GEOS-5 GCM commenced in February 2013.

Also note: the new [[Grid-independent GEOS-Chem#Emissions Component|Grid-Independent Emissions Component]] will also perform this functionality by taking advantage of the regridding features of the Earth System Model Framework.  This is an ongoing development project.

: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.

Revision as of 20:41, 14 May 2013

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 (IGC6) in May 2013 and has been continuously updated since based on code readiness and input from the Working Groups and the Steering Committee.

We also invite you to view our GEOS-Chem Support Team project management board on Trello.com, which shows the current GCST workflow.

List of priorities as of May 2013

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.

To run the nested simulations (the 2 items listed below), we also must be able to run the global simulations with this met data product in order to save out transport boundary conditons.

SiB Fluxes are available to replace the old CASA fluxes, courtesy of Janina Messerschmidt et al. New CASA fluxes would also be good, such that the user can select options in the input.geos file.
