Dear GEOS-Chem Users,
=== Species added ===


Here is the June 2009 GEOS-Chem Newsletter.
Species added between versions 14.5.0-alpha.5 and 14.5.0-alpha.9:
 
''Bob Yantosca, Philippe Le Sager, and Claire Carouge''<br>
''geos-chem-support@as.harvard.edu''
 
== GEOS-Chem Update ==
 
=== GEOS-Chem v8-02-02 ===
 
[[GEOS-Chem v8-02-02]] "beta" has now been released. This version includes:
 
*new boundary layer mixing scheme (developed by Jintai Lin)
*updated Bond emission inventories for BC & OC (prepared by Eric Leibensperger). 
 
This version may be downloaded from:
 
  ftp ftp.as.harvard.edu
  cd pub/geos-chem/beta_releases
  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 [http://www.as.harvard.edu/ctm/geos/geos_steering_cmte.html GEOS-Chem Steering Committee] held a telecon on June 11, 2009.  Click [http://www.as.harvard.edu/ctm/geos/word_pdf_docs/steering_cmte/gc_sc_minutes_061109.pdf HERE] to view the meeting minutes.
 
Since last April's 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:

=== GEOS-Chem Working Groups ===
=== Species removed===


A couple of the [http://www.as.harvard.edu/ctm/geos/geos_steering_cmte.html GEOS-Chem Working Groups] have been renamed:
Species removed between versions 14.5.0-alpha.5 and 14.5.0-alpha.9:
* "Carbon Gases" and "Organics" has been merged into "Carbon Gases & Organics" (co-chairs Dylan Jones, Dylan Millet)
* "Regional Modeling" is now "Regional Air Quality" (co-chairs Rokjin Park, Yuxuan Wang)


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].

For more information about a particular working group, please contact the appropriate Working Group Chairperson(s).
=== Subscribing to the GEOS-Chem email lists ===
There are now several GEOS-Chem email lists:
{| border=1 cellspacing=0 cellpadding=5
|- bgcolor="#cccccc"
!Email list address
!Intended audience
|-
|<tt>geos-chem@seas.harvard.edu</tt>
|All GEOS-Chem users and developers<br>'''''NOTE: This is the email list to which information about <br>new model versions, bugs & fixes, etc. will be sent'''''
|-
|<tt>geos-chem-adjoint@seas.harvard.edu</tt>

|}
To subscribe to any of these lists, please visit the page: https://lists.seas.harvard.edu/mailman/listinfo and then click on the name of the list to which you wish to subscribe.  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 would like to encourage all new GEOS-Chem users to take a moment to read our [[GEOS-Chem welcome letter for new users]]. 
We expect that each GEOS-Chem user will possess at least some familiarity with the following:
* The Fortran programming language (F77 OK, F90 preferred)
* IDL (preferred), or other graphics software (e.g. Splus, Matlab)
* The Unix environment (i.e. commands, file paths, etc.)
* Unix scripts (not strictly required but is very helpful to know!)
The GEOS-Chem support team cannot provide you with general instruction in programming languages or answer general programming questions.  We would like to invite you to view to view the list of tutorials and other relevant resources that are listed on the GEOS-Chem web page at [http://www.as.harvard.edu/ctm/geos/geos_resources.html '''GEOS-Chem Resources Page'''.]
We invite you to read our document on 
[http://www.as.harvard.edu/ctm/geos/word_pdf_docs/resources_guidelines_tips.pdf '''User Resources, Code Development Guidelines, and Debugging Tips'''].
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 update the table of '''[[GEOS-Chem supported platforms and compilers]]''' with your timing information.
=== 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 [[GEOS-Chem Newsletter April-May 2009|April-May 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
* 2006: entire year
* 2007: thru 2007/06/29
* 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
'''''Therefore, the only "missing" data as of June 15, 2009 is the remainder of 2007.'''''
NOTES:
(1) As of June 2009, Harvard's filesystem has been modified.  The directories on the FTP site
  ftp ftp.as.harvard.edu
  cd pub/geos-chem/data
are now a straight mirror of the internal firewall-protected directories.  Any files that are added to the internal directories will be automatically mirrored to the FTP site during the nightly system reboots.  '''''This means that the *.tar.gz files are no longer stored on the FTP site.'''''
(2) As of June 16, 2009, the following dis now available for download:
  Nested China
  ftp ftp.as.harvard.edu
  cd pub/geos-chem/data/GEOS_0.5x0.666_CH.d/GEOS_5/YYYY/MM/
  2 x 2.5 Global (except 2006-2007)
  ftp ftp.as.harvard.edu
  cd pub/geos-chem/data/GEOS_2x2.5.d/GEOS_5/YYYY/MM/
  2 x 2.5 Global (2006-2007 only)
  ftp ftp.as.harvard.edu
  cd pub/geos-chem/data/bmy_temp/GEOS_2x2.5.d/GEOS_5/YYYY/MM/
  4 x 5 Global (except 2006-2007)

  cd pub/geos-chem/data/bmy_temp/GEOS_2x2.5.d/GEOS_5/YYYY/MM/
where <tt>YYYY/MM/</tt> are the year and month that you wish to download.
As you may have noticed, the 2006 and 2007 reprocessed GEOS-5 met data is placed in the "temporary" directory <tt>bmy_temp</tt>.  These met data have also not been placed in a "temporary" folder in the internal firewall-protected directories (so as to avoid confusion w/ the existing met data).  As soon as the complete
'''''Important note!  At present the OTD/LIS lightning flash redistribution has not been done for years 2006-2007.  Therefore, if you run a full-chemistry simulation with 2006 or 2007 reprocessed met fields, the lightning NOx emissions will be incorrect.'''''
== GEOS-Chem column code update ==
We have created a [[GEOS-Chem column code]] wiki page.  At present the page is still under construction, but content will be added here on a regular basis.
The GEOS-Chem column chemistry code has achieved a milestone: the SMVGEAR chemistry solver, as well as the various supporting routines have been columnized and appear to work properly.  More testing will be needed.
Also, several of the chemistry routines for aerosol tracers, including sea salt, dust, and carbon/SOA tracers, have been columnized.  Work is still progressing to columnize the sulfate tracer chemistry routines.
