New features added into GEOS-Chem: | |
Developer name(s) and institution(s): |
|
Version, resolution, met fields used: | v9-01-02, GEOS-5 (47L), 4x5 |
1-month benchmark finished on: | Wed Jul 20 16:47:00 EDT 2011 |
Compared to previous benchmark: | v9-01-02a |
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, Diagnostics, Other (please specify): Chemical species restart file |
Plots may be viewed at: | ftp://ftp.as.harvard.edu/pub/geos-chem/1mo_benchmarks/v9-01-02c/ |
Metrics | |
Global mean OH (from log file): | 13.1838752732688 x 105 molec cm-3 |
Methyl chloroform lifetime: | 4.7493 years |
Did either of these change by more than 5%? | No. The Mean OH is identical to v9-01-02a and the MCL lifetime has a small difference in the very last digit (see Summary Comments). |
At the SURFACE, list all species that changed by 10% or more: | none |

Comments on EMISSION RATIO differences: | |
Additional or summary comments: | NOTE: This update corrects an erroneous situation in the chemical species restart file (aka "CSPEC restart file". This fix ONLY gets invoked for long GEOS-Chem simulations that have to be broken into several stages for the purpose of submitting to computational queues with fixed time limits. When each run stage ends, GEOS-Chem will write the chemical species concentrations into a restart file. When the next run stage begins, GEOS-Chem will read the chemical species information back into the CSPEC array (which gets passed to the SMVGEAR and KPP solvers).
For short simulations that can finish within the time limits of the computatational queues (such as this 1-month benchmark simulation), we do not use the CSPEC restart file. Therefore, when comparing v9-01-01c to v9-01-01a, we should expect to see identical results to v9-01-02a (which we do see as evidenced by the plots and Mean OH concentration). In v9-01-02c, we use the grid box surface areas saved out directly from GEOS-Chem (via the ND69 diagnostic) to compute the MCL lifetime. In v9-01-02a, we computed the grid box surface areas using IDL code. The surface areas from both methods should be similar, but perhaps not strictly numerically equal to all double-precision digits. This causes the very slight difference in the last digit of the MCL lifetime for v9-01-02c. |

Global mean OH (from log file): | 13.1838752732688 x 105 molec/cm3 |

Comments on SURFACE differences: | None |
At 500 hPa, list all species that changed by 10% or more: | NIT, NH3 |
Comments on 500 hPa differences: | Follow up calculations indicate that these changes are owing to an unresolved OpenMP issue, not the v9-01-02a code updates. NIT seems particularly sensitive to this issue, and this probably drives changes in NH3. |
In the ZONAL MEAN differences, list all species that changed by 10% or more: | NOx, N2O5, NIT, NH3 |

|
In the EMISSION RATIO maps, list all species that changed by 10% or more: | None |
