README -- for pub/geos-chem/1yr_benchmarks 01 Mar 2010 Bob Yantosca and Claire Carouge geos-chem-support@as.harvard.edu For more information on the web and wiki: =============================================================================== Please see the following web & wiki links for more information about the GEOS-Chem benchmarks: (1) http://wiki.seas.harvard.edu/geos-chem/index.php/Mean_OH_lifetime_in_GEOS-Chem -- Wiki page which tracks the mean OH lifetime in GEOS-Chem. Provides links to wiki pages with more information about individual GEOS-Chem 1-yr benchmark simulations. (2) http://acmg.seas.harvard.edu/geos/geos_1yr_plots.html -- GEOS-Chem 1-yr plots web page. Provides a list of the models and data plotted for each benchmark simulation. NOTE: Some benchmark runs in the directories below contain incomplete information (i.e. missing log files, bpch files, restarts). Therefore, the Mean OH concentrations for some simulations have not been reported. Directory naming convention: =============================================================================== Output from various GEOS-Chem benchmark simulations are stored in sub- directories of pub/geos-chem/1yr_benchmarks, using this naming convention: VERSION-NUMBER / MET FIELD TYPE / MET FIELD YEAR / RUN DIRECTORY For example, v7-02-03/geos3/2001/Run v7-04-12/geos4/2001/Run0 v7-04-12/geos4/2005/Run1 This lets us to store multiple benchmark simulations for the same GEOS-Chem version number, but allows us to separate them further by met field type and year. Directories containing GEOS-Chem 1-yr benchmark output =============================================================================== old_restarts/ -- Directory containing ancient restart files, mostly from simulations that used GEOS-1 and GEOS-STRAT met fields (which are no longer supported in GEOS-Chem). There are two TARBALL files: (1) restarts_2x25.tar.gz (2) restarts_4x5.tar.gz v4-26/geoss/1997/rvm_2x25/ -- Randall Martin's 2 x 2.5 simulation sfor 1996-1997 using GEOS-STRAT met fields and GEOS-Chem v4-26. v4-26/geoss/1997/rvm_4x5/ -- Randall Martin's 4 x 5 simulation sfor 1996-1997 using GEOS-STRAT met fields and GEOS-Chem v4-26 %%% NOTE: Only the netCDF output files from this run are preserved %%% v4-33/geos3/2001/amf_2x2.5/ -- Arlene Fiore's 2 x 2.5 simulation for 2001 using GEOS-3 met fields w/ GEOS-Chem v4-33 v4-33/geos3/2001/amf_4x5/ -- Arlene Fiore's 4x5 simulation for 2001 (same as above, but w/ 4x5 met fields) v5-05-03/geos3/2005/run.rjp -- Rokjin Park's 4x5 simulation for 2001 with GEOS-3 winds. This was the validation of SMVGEAR II and new fvdas/TPCORE. %%% NOTE: Only the netCDF output files from this run are preserved %%% v5-07-08/geos3/2001/run.mje/ -- Mat Evans' 4 x 5 simulation for 2001 using GEOS-3 met fields and GEOS-Chem v5-07-08 v6-01-05/geos4/2003/run.bmy/ -- Bob Yantosca's 4 x 5 simulation for 2003 using GEOS-4 met fields and GEOS-Chem v6-01-05 v7-02-03/geos3/2001/Run/ v7-02-03/geos4/2001/Run/ -- Bob Yantosca's 4 x 5 simulations for 2001 with GEOS-Chem v7-02-03. GEOS-3 and GEOS-4 met fields are used, in order to assess the impact that the change in meteorology causes in GEOS-Chem. v7-04-02/geos4/2001/wo_megan_1995em/ v7-04-02/geos4/2001/wo_megan/ v7-04-02/geos4/2001/with_megan/ -- Bob Yantosca's 4 x 5 simulations for 2001 with GEOS-Chem v7-04-02 Separate simulations were done for: (a) GEIA biogenic, w/ 1995 fossil fuel scale year (wo_megan_1995em) (b) GEIA biogenic, w/ 1998 fossil fuel scale year (wo_megan) (c) MEGAN biogenic, w/ 1998 fossil fuel scale year (with_megan) v7-04-10/gcap/2001/moeko_gcap/ v7-04-10/geos4/2001/moeko_geos4/ -- Moeko Yoshitomi's 4 x 5 simulations for 2001 with GEOS-Chem v7-04-10 using both GEOS-4 and GCAP met fields v7-04-10/geos4/2004/Run1/ v7-04-10/geos4/2004/Run2/ v7-04-10/geos4/2004/Run3/ v7-04-10/geos4/2004/Run4/ -- Bob Yantosca's benchmark simulations for 2005 using GEOS-4 met fields and GEOS-Chem v7-04-10, designed to test several new emissions options. See the README file for more info: v7-04-10/geos4/2005/README. %%% NOTE: Log files are missing, so we don't have Mean OH info %%% v7-04-12/geos4/2001/Run0/ -- Bob Yantosca's 4 x 5 simulation for 2001 using GEOS-4 met fields and GEOS-Chem v7-04-12 v7-04-12/geos4/2005/Run1/ v7-04-12/geos4/2005/Run2/ -- Bob Yantosca's 4 x 5 simulation for 2001 using GEOS-4 met fields and GEOS-Chem v7-04-12 with the following options: (a) Same lightning & emissions as v7-04-02/geos4/2001/with_megan (b) New lightning (near-land, OTD/LIS), but otherwise same as in Run1 v7-04-13-Run/geos4/2005/Run/ -- Bob Yantosca's 4 x 5 simulation for 2005 using GEOS-4 met fields and GEOS-Chem v7-04-13.

This run is the same as v7-04-13-Run with the following exceptions: (a) Uses GEOS-5 met fields (b) Recycles 2005 met fields (2 years spinup, 1 year simulation) v8-01-01/geos5/2005/Run1/ -- Bob Yantosca's 4 x 5 simulation for 2005 using GEOS-4 met fields and GEOS-Chem v8-01-01. This run is the same as v8-01-01-geos5-Run0 with the following exceptions: (a) Uses RPMARES instead of ISORROPIA for ATE calculations. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% NOTE: All GEOS-Chem versions since v7-03-01 and higher have used ISORROPIA to perform the aerosol thermodynamical equilibrium (ATE) computations. However, we have recently discovered that the version of ISORROPIA that is included in GEOS-Chem does not give realistic results at low relative humidities. See the discussion on the GEOS-Chem wiki: http://wiki.seas.harvard.edu/geos-chem/index.php/Aerosol_thermodynamical_equilibrium Note that: * v8-01-01-geos5-Run0 used ISORROPIA * v8-01-01-geos5-Run1 used RPMARES Therefore you should: * Use v8-01-01-geos5-Run0 to compare to the previous GEOS-4 simulations (e.g v7-04-13 and v7-04-12-Run2), since these also used ISORROPIA. * Use v8-01-01-geos5-Run1 to compare with v8-01-01-Run0 to compare the difference in switching from ISORROPIA to RPMARES. RPMARES will be the default once again in the std GEOS-Chem code for v8-01-01 and higher until further notice. We are working on installing a newer version of ISORROPIA but that will take a while.
