Revision as of 17:40, 4 December 2015
On this page we have posted complete information about all benchmark simulations (both 1-month and 1-year) for GEOS-Chem v11-01.
Contents
1-year benchmarks
v11-01d-RnPbBe
A 1-year Rn-Pb-Be simulation was performed using GEOS-Chem v11-01d. The simulation utilized 4° x 5° GEOS-FP met fields for the year 2013, with a 4-year 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:
Please see the the following links below for complete information about the validation of GEOS-Chem v11-01d.
NOTE: The original v11-01d submitted for approval included a "quick fix" for low Pb tropospheric lifetime against deposition in GEOS-FP and MERRA2. Due to high impact on aerosols, the GEOS-Chem Steering Committee rejected the "quick fix", and we have subsequently removed it from the version and performed an additional 1-year benchmark simulation with the updated model.
Rn-Pb-Be benchmark results for v11-01d after removal of the "quick fix":
TBD

Comments about the 1-year benchmark v11-01b-nPbBe
Daniel Jacob wrote:
- Hongyu, please check out the 15-20% decreases in Pb and Be tropospheric lifetimes against deposition due to scavenging of water-soluble aerosol from cold clouds in 11.1b. Be seems to be improved with reference to your canonical 2001 budget but the Pb loading is 25% lower. What do you think?
Hongyu Liu wrote:
- The tropospheric 210Pb lifetime against deposition of 6.6 days (G-C/GEOS-FP) is the shortest among G-C versions. Switching from GEOS-5 to GEOS-FP met fields (v9-02r) reduced 210Pb lifetime from 9.3 to 7.7 days. See: http://wiki.seas.harvard.edu/geos-chem/index.php/Rn-Pb-Be_simulation#Budget_of_Pb210.
- If v11-01b had been driven by GEOS-5, the 210Pb lifetime may very well be ~8 days.
- Wang, Q. et al. [2014] used G-C/GEOS-5 and "find a lifetime of tropospheric 210Pb aerosol against deposition of 8.6 days, as compared to a best estimate of 9 days constrained by observations [Liu et al., 2001]." So it appears that the short 210Pb lifetime (6.6 days) in v11-01b is largely due to switching to GEOS-FP. Wet deposition needs to be re-evaluated and tuned for GEOS-FP.

Comments about the 1-year benchmark v11-01b-Run0
Aerosol differences
Colette Heald wrote:
- I took a look at the aerosols in the benchmark. There's one thing I don't quite understand: why are the differences between v11-01b and v10-01i so much larger than the differences between v11-01b and v10-01-public at the surface for NIT, NH4, OCPI (see for example the difference plots for Jan or Jul)? According to the table that Melissa linked to the only difference between the two v10-01 runs are bug fixes and the inclusion of UCX and SOA. The NIT/NH4 may be a knock-on effect from changes in SO4 & HNO3, but I'm at a loss for why OCPI changes so significantly. Perhaps I've misunderstood the changes included those simulations?
Melissa Sulprizio wrote:
- The large differences in OCPI are due to the fact that biogenic OC emissions are not calculated in the SOA chemistry mechanism. Before HEMCO, we had the following code in carbon_mod.F:
IF ( LSOA ) THEN ! Total HYDROPHILIC OC source [kg] ! (Don't use archived TERP_ORGC if LSOA=T) OCSRC(I,J,1) = ANTH_ORGC(I,J,1) + & BIOF_ORGC(I,J,1) + & BIOB_ORGC(I,J,1) ELSE ! Total HYDROPHILIC OC source [kg] ! (Use archived TERP_ORGC for if LSOA=F) OCSRC(I,J,1) = ANTH_ORGC(I,J,1) + & BIOF_ORGC(I,J,1) + & BIOB_ORGC(I,J,1) + & TERP_ORGC(I,J) ENDIF
- Christoph Keller has treated OCPI in the same manner in HEMCO. If SOA is turned in in GEOS-Chem v10-01 and later versions, HEMCO will not calculate biogenic OCPI emissions.
- Many of the other differences between v11-01b and v10-01i can be attributed to last-minute fixes that went into v10-01 prior to the public release (see the complete table of fixes and updates). In particular, the following fixes may have contributed to the differences we’re seeing:
- Remove Russia from MIX Asia mask file
- Switching to the officially released GFED4 data files
- Bug fix in I3 field interpolation (affected temperature-dependent emissions)
Jeff Pierce wrote:
- Thanks Melissa. Just to be clear, the SOA mass goes to to the OCPI tracer when the interactive SOA is turned off, but SOA mass goes to other, SOA-specific tracers when the interactive SOA is turned on.
Colette Heald wrote:
- Thanks for the clarifications Melissa. I believe then, that other than the dust issue that Li has flagged up, the aerosols look fine for v11.1
Dust differences
Li Zhang wrote:
- After checking the results, I found that there are some problems with the Dust3 (DST3) concentrations both at the surface and 500 hPa. It is not only different to the 1-month benchmarks that Lizzie sent me, but also different to the results of our simulations based on GEOS-Chem adjoint code. Both in Lizzie's and my results, that the DST3 concentrations are larger after using our dust scheme.
- The DST3 should be supposed to increase, especially over the dust source regions after applying our improved dust scheme. From the dust emission map of DST3, I did see this increase in this benchmarks. However I am surprised that it shows decrease in the concentrations both at the surface and 500 hPa. I am not sure it is due to the coding or only the plotting mistake. It would be great that someone can double check it.
Melissa Sulprizio wrote:
- The dust differences that we see in the 1-year benchmark plots for v11-01b are a combination of the following updates:
- The second item was identified by Duncan Fairley when we implemented his acid uptake on dust scheme (default off) into the standard code.
- The improved dust size distribution scheme decreased DST1 and DST2, while it increased DST3 and DST4. The wet scavenging fix to dust decreased DST2 and DST3.
Colette Heald wrote:
- Thanks for the clarification. I can see that this makes sense given the changes. I discussed this with Dave, and I'll just note here (more for the benefit of Jeff and Peter) that the net effect of these changes does appear to be moving us in the wrong direction. The model already underestimates dust export/transport and these further reductions will exacerbate that. Something for us to keep an eye out in the future...
David Ridley wrote:
- We’ve mainly been focusing on removal in the outflow from Africa, but there seems to be too much removal in general based on the gradient in dust AOD away from source. However, I’m finding a general lack of dust from Asia in GC too, which is contrary to some previous work. Much of low bias we’re seeing (relative to satellite) comes from earlier and later in the year than the Wang et al. (2012) and Ku et al. (2011) studies that I know of – although the latter study shifts dust emissions around, rather than decreasing them substantially. We’ve been looking over a period of several years, so it is tricky to relate that to the above studies that focus on periods of days to weeks.
- It sounds like Duncan’s fix makes sense, but it does highlight potential issues with emission and removal of dust in the model.

1-month benchmarks
v11-01d
Here is the assessment form for 1-month benchmark simulation v11-01d.
NOTE: The v11-01d 1-month benchmark results in this form included a quick fix for low Pb tropospheric lifetime against deposition in GEOS-FP and MERRA2. Due to the high impact on aerosols, the GEOS-Chem Steering Committee rejected the quick fix. We have subsequently removed this fix from v11-01d and performed additional 1-year benchmark simulations with the updated model. The results below do not reflect the updated version of v11-01d except where specified.

Requires further investigation: | September 3, 2015 update: Version 11-01a dry mixing ratios show a moisture artefact while tracer total mixing ratios [kg/kg] do not show a moisture artefact. There is debate over which mixing ratio, dry or total, should show the moisture artefact.
Legacy versions of GEOS-Chem appear to rely on an implicit assumption of the "same" mixing ratio throughout, including input, output, and transport. Given that total air mass is used for conversions, we assume this "same" mixing ratio is total mixing ratio. Given that (1) legacy versions of GEOS-Chem use the "same" mixing ratio for transport and input/output, and (2) mixing ratios in legacy versions of GEOS-Chem do not show a moisture signature, then it makes sense that we now see a moisture signature in the input/output dry mixing ratio but not the total mixing ratio. This is because the tracer mass distribution is driven by transport not the restart file concentration. To address this issue, we will change input and output to be total mixing ratio and use total air rather than dry air molecular weight to extract moles from total mixing ratio where necessary. This will make v11-01a consistent with legacy GEOS-Chem while correcting the mixing ratio to mass unit conversion error that was the primary motivation for v11-01a. This change will be incorporated into a future v11-01 version. The Carbon and Transport Working Groups will look into the issue of the moisture signature in dry vs. total mixing ratio and provide a recommendation. |
