Here we have posted links to a separate wiki page describing each GEOS-Chem model version.
This page contains links to wiki pages describing past GEOS-Chem model releases. For information about upcoming releases see the [[GEOS-Chem model development priorities|'''GEOS-Chem model development priorities wiki page''']].


== Current GEOS-Chem version(s) in development ==
== GEOS-Chem development history ==
 
In the tables below, we list information about current and past GEOS-Chem releases.
 
Some notes for the tables below:
*Information about benchmarks can be found by following the links in the "Benchmarks" column
*GCC = GEOS-Chem "Classic" (uses OpenMP parallelization single node only)
*GCHP = GEOS-Chem High Performance (uses MPI parallelization across multiple nodes)
*DOI = digital object identifier, can be used to reference individual GEOS-Chem versions in publications
*AMI = Amazon Machine Image, which provides GEOS-Chem Classic on the AWS Cloud
 
Also see our [[GEOS-Chem version numbering system]] wiki page for information on how GEOS-Chem versions are labeled.

Here is a plot of the [[Mean OH lifetime in GEOS-Chem|mean OH concentration]] from several recent GEOS–Chem 1-year benchmark simulations. The mean OH is an indicator how the chemistry mechanism is performing. Typical values are 10–11 x 10<sup>5</sup> molecules cm<sup>-1</sup>.

NOTES:
|}
#Runs done with GEOS-3 met are denoted by squares; GEOS-4 met: triangles; GEOS-5 met: circles.
#The large jump in mean OH between [[GEOS-Chem v8-01-04#Run2|v8-01-04-Run2]] and [[GEOS-Chem v8-02-01#Run0|v8-02-01-Run0]] is likely attributed to the photolysis rate updates for ketones and aldehydes. See [http://acmg.seas.harvard.edu/geos/wiki_docs/chemistry/chemistry_updates_v4.pdf this document] about the new photolysis mechanism. However, we are still investigating this.
#The runs done with GEOS-4 met have higher mean OH than the GEOS-3 and GEOS-5 runs because of the missing high cloud optical depth in the GEOS-4 met fields.
#The large jump upward from [[GEOS-Chem v7-04-12#Run1|v7-04-12-Run1]] to [[GEOS-Chem v7-04-12#Run2|v7-04-12-Run2]] is attributed to a major upgrade of the lightning NOx algorithm. v7-04-12 was the first GEOS-Chem version to redistribute flashes regionally according to OTD/LIS statistics.
#[[GEOS-Chem v7-04-13|v7-04-13]] uses the same lightning algorithm as in [[GEOS-Chem v7-04-12#Run2|v7-04-12-Run2]]. However, the lightning flash redistribution according to OTD/LIS statistics was switched from regional to local redistribution.
#v7-04-02-Run0 and v7-04-02-Run1 used GEIA biogenic emissions. v7-04-02-Run2 swiched to MEGAN biogenic emissions.
#[[GEOS-Chem v8-02-04#Run0|v8-02-04-Run0]] used the new [[MEGAN biogenic emissions#MEGAN in GEOS-Chem v8-02-04 and later versions|MEGAN v2.1 biogenic emissions]] with the old AVHRR-derived LAI product.  This caused the mean OH to be much lower than runs [[GEOS-Chem v8-02-04#Run1|v8-02-04-Run1]] and [[GEOS-Chem v8-02-04#Run2|v8-02-04-Run2]], which used the newer MODIS LAI product.  See the full discussion [[MEGAN biogenic emissions#Use MEGAN with MODIS leaf area indices|HERE]].

== GEOS–Chem Benchmarking Procedure ==
 
'''GEOS-Chem Benchmarking Protocol<br>adopted at the 5th International GEOS-Chem Meeting (May 2011)'''
 
#<p>Any change to the GEOS–Chem source code will require a dedicated 1-month "full-chemistry" benchmark and a version update code a,b,c... (such as v9–01–02a). These final letter codes are for internal use only and do not represent a version release. The benchmark results will be posted publicly with an email sent to the [http://acmg.seas.harvard.edu/geos/geos_steering_cmte.html GEOS–Chem Steering Committee].</p>
#<p>The developer will assess the benchmark results by filling out a form (created by Colette Heald and adapted to a wiki page) for all to see. If the developer has any concerns about the benchmark results they will contact the [[GEOS-Chem Support Team]], the relevant [http://acmg.seas.harvard.edu/geos/geos_working_groups.html GEOS–Chem Working Group Chairs], or Model Scientist Daniel Jacob.  GEOS–Chem Steering Committee members can also comment on the benchmark results if they desire.</p>
#<p>Once the developer is satisfied, GEOS–Chem Model Scientist Daniel Jacob will quickly review the results and approve the new internal version.</p>
#<p>1-year benchmarks for these internal version updates will be conducted only if justifiably requested by the developer or by GEOS–Chem Steering Committee members.</p>
#<p>Each new version release (such as v9–01–02) will be subject to a 1-year benchmark to be inspected by the GEOS–Chem Steering Committee before approval (as was done for v9–01–01).  Changes will be bundled so that we will have new versions released only every 4 months or so — this has been our rhythm in recent years.</p>
 
Also, for each new version, we shall perform a standard 1-year [[Rn-Pb-Be simulation]].  This type of simulation is useful in examining if there are any significant impacts in convection or wet scavenging.
 
For more information about the standard 1-month and 1-year benchmark simulations, please see our [http://acmg.seas.harvard.edu/geos/geos_benchmark.html GEOS-Chem Benchmarking web page].

This page contains links to wiki pages describing past GEOS-Chem model releases. For information about upcoming releases see the GEOS-Chem model development priorities wiki page.

GEOS-Chem development history

In the tables below, we list information about current and past GEOS-Chem releases.

Some notes for the tables below:

  • Information about benchmarks can be found by following the links in the "Benchmarks" column
  • GCC = GEOS-Chem "Classic" (uses OpenMP parallelization single node only)
  • GCHP = GEOS-Chem High Performance (uses MPI parallelization across multiple nodes)
  • DOI = digital object identifier, can be used to reference individual GEOS-Chem versions in publications
  • AMI = Amazon Machine Image, which provides GEOS-Chem Classic on the AWS Cloud

Also see our GEOS-Chem version numbering system wiki page for information on how GEOS-Chem versions are labeled.
