Revision as of 22:31, 7 December 2011

On this page we have posted complete information about all benchmark simulations (both 1-month and 1-year) for GEOS-Chem v9-01-03.

v9-01-03a

Here is the assessment form for 1-month benchmark simulation v9-01-03a.

Description
New features added into GEOS-Chem:
Developer name(s) and institution(s):
  • Fabien Paulot (Harvard)
Version, resolution, met fields used: v9-01-03, GEOS-5 (47L), 4x5
1-month benchmark finished on: Fri Dec 2 17:57:14 EST 2011
Performance statistics:
  • Ran on 8 CPUs of terra-02-c.as.harvard.edu (2.659 GHz x 8 CPU)
  • Wall time: 1:38
  • Scalability: 7.4772
Compared to previous benchmark: v9-01-02s
This update will impact:
(select all that apply with boldface)
Advection, BL Mixing, Convection, Met Fields, Dry Dep, Wet Dep, Stratosphere, Anthro Emiss, Biogenic Emiss, Biomass Emiss, Photolysis, Chemistry, Other (please specify): Tropopause
Plots may be viewed at: ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03a/
Metrics
Global mean OH (from log file): 13.3152237747292 x 105 molec/cm3
Methyl chloroform lifetime: 4.7044 years
Did either of these change by more than 5%? No
At the SURFACE, list all species that changed by 10% or more:

PAN (downwind of South America), ALK4 over oceanic basins, ISOP downwind of South America, MEK tropics, MVK, MACR (downwind of South America), PMN, PPN, PRPE, N2O5, DMS

Comments on SURFACE differences:

Sort of makes sense. Changes are in regions that are NOx starved (South America) or cold (the loss from GLPAN will be greatest). Changes are small overall and almost always negative. The changes for DMS are relatively large (10-20% decrease)

At 500 hPa, list all species that changed by 10% or more:

ALK4, ISOP, MEK, MVK, MACR, PRPE (large changes in polar regions > 20%), DMS

Comments on 500 hPa differences:

Changes are generally bigger than at the surface (temperature dependence of GLPAN)

In the ZONAL MEAN differences, list all species that changed by 10% or more:

ISOP (but at high altitude and in polar regions), ALK4 in polar regions, MEK, MVK, MACR, PMN, PRPE

Comments on ZONAL MEAN differences:

Small changes overall (in an absolute sense). DMS has the largest change.

In the EMISSION RATIO maps, list all species that changed by 10% or more:
