Overview
BETA RELEASE October 2007
- Previous version: v7-04-11
- Next version GEOS-Chem v7-04-13
What's new in this version
- Variable tropopause has bug fix from v7-04-11 but not 200 hPa cap at polar latitudes
- NOTE: There is a bug in this version when lightning emissions are turned off. The bug will be fixed in GEOS-Chem 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.
1-Year Benchmarks
We have already done the following 1-year benchmark simulations:
Run1
In FTP directory: /as2/pub/ftp/pub/geos-chem/1yr_benchmarks/v7-04-12/geos4/2005/Run1
View output plots via the web HERE.
- 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 FAST-J photolysis
- with variable tropopause on
Mean OH: 11.763 [1e5 molec/cm3]
Run2
In FTP directory: /pub/geos-chem/1yr_benchmarks/v7-04-12/geos4/2005/Run2
View output plots via the web HERE.
- Same as Run1, but uses new lightning parameterization (with OTD/LIS v2 regional redistribution of flashes)
Mean OH: 12.816 [1e5 molec/cm3]
