1-month benchmarks
v9-02r
NOTE: For v9-02r, we performed 1-month benchmarks with both GEOS-FP and GEOS-5 meteorology. We shall now use GEOS-FP meteorology for all 1-month (and 1-year) benchmarks for all future GEOS-Chem versions.

Additional or summary comments: |
Despite using a different set of met fields for a different year, the v9-02r GEOS-FP mean OH only differs by less than -1% from the v9-02r GEOS-5 benchmark. We may take this as evidence that the GEOS-FP simulation in GEOS-Chem is performing adequately, and that there are no major surprises. Further testing will be needed with the 1-year benchmark simulation. We also note the following similarities and differences between v9-02 GEOS-FP and v9-02 GEOS-5 benchmark simulations:

Metrics | |
Global mean OH (from log file): | 13.8467219229137 x 105 molec/cm3 |
Methyl chloroform lifetime: | 4.4899 years |
Did either of these change by more than 5%? | No |
At the SURFACE, list all species that changed by 10% or more: | NH3, NIT |
Comments on SURFACE differences: |
NH3 differences over Canada are to be expected because we now use corrected CAC emissions files. |

Comments on ZONAL MEAN differences: |
NH3: Small number differences caused by corrected CAC emissions files |
In the EMISSION RATIO maps, list all species that changed by 10% or more: | NH3 |
Comments on EMISSION RATIO differences: | NH3: Observed differences over Canada are to be expected because we are now using corrected CAC emissions files. |
Additional or summary comments: | Most of the changes in this version were to include the GEOS-FP met fields. As a result, we observe mostly minor differences in the output. NH3 emissions over Canada have changed due to the fact that we are now using corrected CAC emissions files with the proper seasonality. We have also made several minor bug fixes to increase numerical stability, which may be responsible for some of the minor differences in the other tracers that we observe.
We will perform 1-month and 1-year benchmarks with the new GEOS-FP met fields. Those results will be posted here shortly. |

Comments on SURFACE differences: | The removal of NOx-Ox partitioning has resulted in less NO with respect to NOx. O3 remains unchanged with respect to Ox, except for in the Antarctic, where O3 is larger than Ox by 3 ppb or less. This change is primarily due to the restart file. A restart file was spun up for the 5 new tracers and combined with the existing benchmark restart file, resulting in slightly different initial conditions for O3 with respect to Ox. The introduction of the new tracers has also caused slight differences in N2O5 over source regions.
Differences in NH4 and NIT can be attributed to numerical noise from ISORROPIA. Differences in the remaining species primarily occur over the oceans or over Antarctica and can be attributed to small number differences where concentrations are very low. |

Additional or summary comments: | Please note that family tracers NOx and Ox have been removed in this version and replaced with tracers NO, O3, NO2, NO3, and HNO2. Therefore, the first two panels on several of the benchmark plots (i.e. differences, ratios, zonal differences) compare NO and O3 from the current version with NOx and Ox from the previous version (v9-02g).

N2O5 HNO4 DMS, MSA Br, BrO, Other bromine compounds |
Comments on SURFACE differences: | Isoprene related tracers: Concentrations are changing over remote oceanic regions reflecting changes in the initial oxidation steps of these compounds.
N2O5 changes are again is restricted to remote ocean regions. Changes to the NO3+DMS rate constant have made this faster which will tend to reduce NO3 and N2O5 concentrations in regions where DMS is the dominant VOC DMS, MSA Concentrations are changing due to changes in the DMS+OH and DMS+NO3 rate constants. At the surface changes are small and restricted to continental regions. Br compounds. These are restricted to the polar regions where concentrations are low and reflects the combination of other changes of longer lived species. The same is the case for HNO3. |
At 500 hPa, list all species that changed by 10% or more: | NOx
ISOP, MVK, MACR, PMN N2O5 HNO4 PRPE DMS, MSA NIT, NH4 Br species |
Comments on 500 hPa differences: | The largest changes here are to the DMS and MSA. This reflects the changes in the DMS+OH and DMS+NO3 oxidation routes which essentially both changes the location of DMS oxidation and the branching ratio of the DMS Oxidation
isoprene chemistry changes again reflect changes in the primary oxidation of isoprene and the subsquent branching ration NIT, NH4 Isoropia seems unstable at cold temperatures and small changes leads to large relative changes in these compounds even though they are at low concentrations. N2O5, HNO4, Br species see above. |

ISOP, MVK, MACR, PMN PRPE CH2O N2O5 HNO4 MP DMS, MSA, SO2 Br compounds |
Comments on ZONAL MEAN differences: | NOx, HNO3, H2O2, CH2O, MP Reflect that changes seen in Browne et al., 2011
DMS, MSA, SO2 reflect changes in the initial DMS oxidation of DMS+OH and DMS+NO3 ISOP, MACR, MVK, PMN changes reflect changes in the ISOP oxidation ISOP+OH, O3, NO3 The N2O5 decrease at ~200 hPa in the zonal mean is also consistent with Browne et al., 2011 |
In the EMISSION RATIO maps, list all species that changed by 10% or more: | No |

At 500 hPa, list all species that changed by 10% or more: | ISOP, NH3, NIT |
Comments on 500 hPa differences: | Differences are seen in ISOP in locations where concentrations are already very low (i.e. over oceans). These differences are attributed to the bromine bug fix.
Differences in NH3 and NIT are attributed to the numerical noise issue in ISORROPIA II. |
In the ZONAL MEAN differences, list all species that changed by 10% or more: | ALK4, ISOP, PRPE, C3H8, SO4s, NH3, NIT, NITs, Br2, |

Additional or summary comments: | When ISORROPIA is turned off, and when the Bug fix for Br2 emissions is also added to v9-02c, then we obtain identical results between v9-02c and v9-02d. This demonstrates that the structural modifications made for grid independence do not change GEOS-Chem's scientific results. Most of these modifications were made to carry data fields in derived-type objects rather than in module arrays, but the data fields themselves have not changed. |

At the SURFACE, list all species that changed by 10% or more: | NOx, Ox, PAN, ALK4, ISOP, HNO3, H2O2, MEk, ALD2, RCHO, MVK, MACR, PMN, PPN, R4N2, PRPE, C3H8, CH2O, N2O5, HNO4, MP, DMS, SO2, SO4, SO4s, MSA, NH3, NH4, NIT, NITs, Br2, Br, BrO, HOBr, HBr, BrNO2, BrNO3, and OH |
Comments on SURFACE differences: | The changes are as expected. The new soil NOx parameterization significantly increases the NOx concentrations over North America, the southern part of South America, Central Asia and parts of Africa. Decreases occur over the northern part of South America, central Africa and Indonesia.
Other species are influenced by resulting changes in O3 (and consequently OH). However, some of the reported changes are mainly caused by noise since the absolute differences are very close to zero. |
At 500 hPa, list all species that changed by 10% or more: | NOx, PAN, ALK4, ISOP, HNO3, MEK, ALD2, RCHO, MVK, MACR, PMN, PPN, PRPE, N2O5, HNO4, MP, DMS, SO2, MSA, NH3, NIT, NITs, Br2, Br, BrO, HOBr, HBr, BrNO2, BrNO3, and OH |

Comments on ZONAL MEAN differences: | See 'Comments on SURFACE differences' |
In the EMISSION RATIO maps, list all species that changed by 10% or more: | NOx fertilizer emissions and NOx soil emissions |
Comments on EMISSION RATIO differences: | The NOx soil emissions diagnostic now includes the NOx fertilizer emissions since the emissions related to fertilizer are now calculated using the same procedure as the “regular” soil emissions based on the biome emission coefficients. The soil NOx emission total increases with 0.310 Tg N to 1.028 Tg N for July.
The fertilizer emissions diagnostics gives the soil NOx emissions related to fertilizer use and deposited nitrogen. |
Additional or summary comments: | The occurring changes are as expected. The benchmark is performed using a new soil NOx restart file which saves per grid cell:
The overall changes are in NOx emissions are consistent with those in Hudman et al. (2012) with the additional canopy reduction that Bram added. The changes in O3 and OH follow the changes in NOx emissions. |

Special benchmarks
v9-02r Rn-Pb-Be
Karen Yu performed 1-year Rn-Pb-Be simulations using GEOS-Chem v9-02r to evaluate the GEOS-FP met fields. The simulations were done for June 2012–May 2013, with a 2-month spinup. For comparison of the Pb-210 and Be-7 budgets to previous versions, please see the following posts on the Rn-Pb-Be simulation wiki page:

v9-02o SOA
One-month benchmark simulations were performed for v9-02n using the traditional SOA simulation and for v9-02o using the updated SOA simulation. The optional semivolatile POA and IVOC features were turned off in the updated SOA simulation. The standard 1-month benchmark plots comparing these simulations were created to evaluate tracers 1-66. The benchmark plots are stored in the output/ directory of this *.tar.gz file:

- I've gone through and compared the SOA and SOG tracer concentrations for the simulations using Havala's SOA scheme vs. the old-school SOA scheme. Everything seems to make sense including (1) the partitioning between SOA and SOG for the various volatility bins, (2) the spatial dependence of the terpene-based, isoprene-based and anthro-based SOA, and (3) the magnitude of the concentrations compared to the old-school scheme. There may be some subtleties that Havala may be able to spot, but there was nothing I was able to see that looked odd. There seems to be no impact on the other species in the ratio and difference maps.

- I concur with Jeff. The v9-02o benchmark looks good in terms of magnitude and spatial variability.
