Since the GEOS-Chem meeting, a number of [[GEOS-Chem model development priorities]] that were identified by the Steering Committee and Working Groups have now been implemented into GEOS-Chem:

 +
We ask that each GEOS-Chem user join the [http://www.as.harvard.edu/ctm/geos/geos_working_groups.html Working Group] that is most relevant to his/her area of research.  The Working Groups are meant to foster communication and information sharing between GEOS-Chem users, as well as to identify [[GEOS-Chem_model_development_priorities|priorities for model development]] to the [http://www.as.harvard.edu/ctm/geos/geos_steering_cmte.html GEOS-Chem Steering Committee].

Each GEOS-Chem user is also expected to adhere to our list of [http://www.as.harvard.edu/ctm/geos/geos_best_practices.html best practices].
 +
 +
We also would like to invite all GEOS-Chem users outside Harvard who have run the 1-month benchmark simulation on their own systems to take a moment and to update the table of [[GEOS-Chem supported platforms and compilers]] with your timing information.

 +
 +
 +
An additional 1-year benchmark ([[GEOS-Chem v8-01-04#Run2|v8-01-04 Run2]]) was performed so that we could have a clean comparison between the "reprocessed" GEOS-5.1.0 met fields and the older GEOS-5.0.1 met fields.  For more information about the different GEOS-5 versions, see [http://gmao.gsfc.nasa.gov/pubs/docs/GEOS5_104606-Vol27.pdf this document from GMAO].

The result was an integrated adjoint code based on v8-02-01 with GEOS-5 and including updates from the different groups, improved file formats and input files, etc.

Dear GEOS-Chem Users,

Here is the June 2009 GEOS-Chem Newsletter.

GEOS-Chem Update

GEOS-Chem v8-02-02

GEOS-Chem v8-02-02 "beta" has now been released. This version includes the new boundary layer mixing scheme (developed by Jintai Lin) as well as updated Bond emission inventories for BC & OC (prepared by Eric Leibensperger). The new version may be downloaded from:

 ftp ftp.as.harvard.edu

 get GEOS-Chem.v8-02-02-beta.stdrun.tar.gz

NOTE: We currently working on enabling access to our CVS repository to outside users so that you will be able to obtain the GEOS-Chem source code without having to download a large TAR file. Stay tuned...

GEOS-Chem Steering Committee

The GEOS-Chem Steering Committee held a telecon on June 11, 2009. Click [HERE] to view the meeting minutes.

GEOS-Chem Working Groups

A couple of the GEOS-Chem Working Groups have been merged together:

  • "Carbon Gases" and "Organics" is now "Carbon Gases & Organics" (co-chairs Dylan Jones, Dylan Millet)
  • "Regional Air Quality"

You will be taken to a page where you can specify your email address and a password and then click SUBMIT. You will then receive a confirmation email from the system. Follow the directions in the confirmation email and then you will be added to the list.

PLEASE NOTE: If you wish to send an email to any of the above GEOS-Chem mailing lists, then please be sure to send your email from the same address with which you subscribed to the list. Otherwise your email may bounce back to you. The GEOS-Chem mailing lists are set up to reject emails from non-list members. This is done in order to prevent spam.

Being a member of the GEOS-Chem community

We ask that each GEOS-Chem user join the Working Group that is most relevant to his/her area of research. The Working Groups are meant to foster communication and information sharing between GEOS-Chem users, as well as to identify priorities for model development to the GEOS-Chem Steering Committee.

Each GEOS-Chem user is also expected to adhere to our list of best practices.

We also would like to invite all GEOS-Chem users outside Harvard who have run the 1-month benchmark simulation on their own systems to take a moment and to update the table of GEOS-Chem supported platforms and compilers with your timing information.


An additional 1-year benchmark (v8-01-04 Run2) was performed so that we could have a clean comparison between the "reprocessed" GEOS-5.1.0 met fields and the older GEOS-5.0.1 met fields. For more information about the different GEOS-5 versions, see this document from GMAO.

Adjoint Model Update

A successful meeting was held at Virginia Tech to develop a standard version of the GC adjoint merging the capabilities developed by individual groups: participants were Kumaresh Singh, Adrian Sandu, Monika Kopacz, Changshub Shim, and Daven Henze. The result was an integrated adjoint code based on v8-02-01 with GEOS-5 and including updates from the different groups, improved file formats and input files, etc.

GEOS-5 met field reprocessing

Status

As described in the March 2009 newsletter, we are reprocessing the entire archive of GEOS-5 met field data. As of May 6, 2009 the following fields have been completed:

  • 2003: December only
  • 2004: entire year
  • 2005: entire year
  • 2008: entire year

for each of the following geographic domains:

  • China nested 0.5 x 0.667
  • Global 2 x 2.5
  • Global 4 x 5

The files have been TAR'd and Gzip'd for your convienience (as this dramatically reduces the size of the data). In each directory there are files 01.tar.gz, 02.tar.gz .. 12.tar.gz, each of which contains a single month of met field data. GEOS-Chem users outside Harvard may obtain these data files via anonymous FTP:

 ftp ftp.as.harvard.edu
 cd pub/geos-chem/data/GEOS_0.5x0.666_CH.d/GEOS_5/2008
 mget *.tar.gz
 cd pub/geos-chem/data/GEOS_2x2.5.d/GEOS_5/2008
 mget *.tar.gz
 cd pub/geos-chem/data/GEOS_4x5.d/GEOS_5/2008
 mget *.tar.gz
 cd pub/geos-chem/data/GEOS_0.5x0.666_CH.d/GEOS_5/2004
 mget *.tar.gz
 cd pub/geos-chem/data/GEOS_2x2.5.d/GEOS_5/2004
 mget *.tar.gz
 cd pub/geos-chem/data/GEOS_4x5.d/GEOS_5/2004
 mget *.tar.gz

However, to simplify the FTP process you might want to use a 3rd party FTP software program with a GUI interface, such as Mozilla FireFTP.

We are currently working on reprocessing GEOS-5 met data for 2006; however, this effort has been slowed down by some filesystem problems at Harvard.

ESMF update

Development of the GEOS-Chem column chemistry module continues to proceed swiftly. The SMVGEAR solver has been columnized and is now in testing to ensure that it gives similar results to the existing GEOS-Chem. Also, the dust, sea salt, and carbon aerosol chemistry routines have been columnized and are working correctly.
