# [[NOx-Ox-HC-aerosol#Variable_Tropopause|Variable tropopause]] has bug fix from v7-04-11 but not 200 hPa cap at polar latitudes
+
Please see the separate wiki page for [[GEOS-Chem v7-04-12]].
# NOTE: There is a bug in this version when [[Lightning_NOx_emissions#The common block bug fix|lightning emissions are turned off]].  The bug will be fixed in [[GEOS-Chem_versions_under_development#v7-04-13|v7-04-13]].  For the time being, if you must turn lighting emissions off in v7-04-12, please do this by setting FLASHRATE = 0 in the lightning_nox_nl_mod.f.

We have already done the following 1-year benchmark simulations:

==== Run1 ====

In FTP directory: <tt>/as2/pub/ftp/pub/geos-chem/1yr_benchmarks/v7-04-12/geos4/2005/Run1</tt>

* Run w/ 4x5 GEOS-4 for met field year 2005 (spun up thru 2003 & 2004)
+
* with G-C "old" fossil fuel (GEIA + EPA/NEI99)
+
* with G-C "default" climatological biomass burning
+
* with old lightning parameterization
+
* with MEGAN biogenic emissions
+
* with SMVGEAR chemistry up to dynamic tropopause
+
* with new dust emissions (w/ GOCART source function)
+
* with new TOMS/SBUV ozone columns for [[Photolysis mechanism|FAST-J photolysis]]
+
* with variable tropopause on
