Version, resolution, met fields used: v9-01-03, GEOS-5 (47L), 4x5
1-month benchmark finished on: Wed Feb 15 15:30:13 EST 2012
Performance statistics:
  • Ran on 8 CPUs of terra-10-c.as.harvard.edu (2.659 GHz x 8 CPU)

Advection, BL Mixing, Convection, Met Fields, Dry Dep, Wet Dep, Stratosphere, Anthro Emiss, Biogenic Emiss, Biomass Emiss, Photolysis, Chemistry, Other (please specify):
Plots may be viewed at: ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03f/
Metrics
Global mean OH (from log file): 13.1254879976765 x 105 molec/cm3
Methyl chloroform lifetime: 4.7576 years
Did either of these change by more than 5%? No
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, OH
Comments on SURFACE differences: In original model, ship NOx was released as 10*O3 and 1*HNO3 molecules (continuously, day and night). Now we release a fraction of the NOx, and O3 and HNO3 produced. This explains large increase in NOx, as no ship NOx was present before this update. Other species are influenced by changes in O3 (and consequently OH).
At 500 hPa, list all species that changed by 10% or more: NOx, ISOP, MVK, MACR, PMN, PRPE, N2O5, HNO4, DMS, SO2, MSA, NH3 (noisy), NIT (noisy), NITs
Comments on 500 hPa differences:

Comments on ZONAL MEAN differences: Most of the effects are concentrated near the surface and in the lat range 0..60, where most of the ship emissions are located.
In the EMISSION RATIO maps, list all species that changed by 10% or more: NOx
Comments on EMISSION RATIO differences: Instead of emitting no ship NOx, we now release a fraction of the ship NOx (+O3 and HNO3 produced).
Additional or summary comments: Streets bugfix only influences model runs before 2000 or nested Asia simulation (see Bug fixes for David Streets emissions for years 2005 and earlier)
Approval
Requires further investigation: No
Approved: Yes
Date of approval: TBD

v9-01-03e

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

Description
New features added into GEOS-Chem:
Developer name(s) and institution(s):
  • Scavenging improvements: Qiaoqiao Wang (Harvard)
  • Washout structural update: Helen Amos (Harvard)
Version, resolution, met fields used: v9-01-03, GEOS-5 (47L), 4x5
1-month benchmark finished on: Fri Jan 20 13:26:06 EST 2012
Performance statistics:
  • Ran on 8 CPUs of terra-08-c.as.harvard.edu (2.926 GHz x 8 CPU)
  • Wall time: 1:13
  • Scalability: 7.7027
Compared to previous benchmark: v9-01-03d
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):
Plots may be viewed at: ftp://ftp.as.harvard.edu/gcgrid/geos-chem/1mo_benchmarks/v9-01-03e/
Metrics
Global mean OH (from log file): 13.0850715760517 x 105 molec/cm3
Methyl chloroform lifetime: 4.7757 years
Did either of these change by more than 5%? No
At the SURFACE, list all species that changed by 10% or more: NOx, PAN, ISOP, HNO3, H2O2, MVK, PPN, PRPE, N2O5, HNO4,SO2, SO4, SO4s, MSA, NH3, NH4, NIT, NITs, BCPI, BCPO, OCPI, OCPO, DST1, DST2, DTS3, DST4, SALA, SALC
Comments on SURFACE differences: The differences are mainly due to the changes in below-cloud scavenging for aerosols. The below-cloud scavenging is very efficient for coarse sea salt and coarse dust, but not for other aerosols.
At 500 hPa, list all species that changed by 10% or more: NOx, ALK4, ISOP, HNO3, MVK, MACR, PMN, PRPE, N2O5, HNO4, MP, DMS, SO2, SO4, SO4s, MSA, NH3, NH4, NIT, NITs, BCPI, BCPO, OCPI, OCPO, DST1, DST2, DTS3, DST4, SALA, SALC
Comments on 500 hPa differences: The significant decreases in DUST, BCPO and HNO3 are because of the in-cloud scavenging by snow.
In the ZONAL MEAN differences, list all species that changed by 10% or more: NOx, ALK4, ISOP, HNO3, H2O2, MVK, MACR, PMN, PRPE, N2O5, HNO4, MP, DMS, SO2, SO4, SO4s, MSA, NH3, NH4, NIT, NITs, BCPI, BCPO, OCPI, OCPO, DST1, DST2, DTS3, DST4, SALA, SALC, OH
Comments on ZONAL MEAN differences: Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation.
In the EMISSION RATIO maps, list all species that changed by 10% or more: No
Comments on EMISSION RATIO differences:

v9-01-03d

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

Description
New features added into GEOS-Chem:
Developer name(s) and institution(s):
  • Sea salt improvements: Lyatt Jaeglé (U. Washington)
  • Dry deposition: Lyatt Jaeglé (U. Washington) and GEOS-Chem Support Team
  • Dust submicron size distribution: David Ridley (Colo. State)
Version, resolution, met fields used: v9-01-03, GEOS-5 (47L), 4x5
1-month benchmark finished on: Tue Jan 10 19:18:47 EST 2012
Performance statistics:
  • Ran on 8 CPUs of terra-12-c.as.harvard.edu (2.670 GHz x 8 CPU)
  • Wall time: 1:32
  • Scalability: 7.6956
Compared to previous benchmark: v9-01-03c
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): Sea salt emissions & deposition, Dust AOD
Plots may be viewed at: ftp://ftp.as.harvard.edu/gcgrid/geos-chem/1mo_benchmarks/v9-01-03d/
Metrics
Global mean OH (from log file): 13.3024776896910 x 105 molec/cm3
Methyl chloroform lifetime: 4.7075 years
Did either of these change by more than 5%? No
At the SURFACE, list all species that changed by 10% or more: SALA, SALC, N2O5, HNO3, NIT, NITs, NH4, NH3, SO4s, HNO4, NOx, PAN
Comments on SURFACE differences: Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.

The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.

At 500 hPa, list all species that changed by 10% or more: SALA, SALC, SO4s, NH3, NIT, NITs
Comments on 500 hPa differences:
In the ZONAL MEAN differences, list all species that changed by 10% or more: SALA, SALC, HNO3, N2O5, HNO4, SO4s, NH4, NIT, NITs
Comments on ZONAL MEAN differences: Most of the effects are concentrated near the surface, where the sea salt burden is highest.
In the EMISSION RATIO maps, list all species that changed by 10% or more: SALA, SALC
Comments on EMISSION RATIO differences: As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.

Performance statistics:
  • Ran on 8 CPUs of terra-10-c.as.harvard.edu (2.659 GHz x 8 CPU)
  • Wall time: 1:39
  • Scalability: 7.2830
Compared to previous benchmark: v9-01-03a
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):
Plots may be viewed at: ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03b/
Metrics
Global mean OH (from log file): 13.2811407896285 x 105 molec/cm3
Methyl chloroform lifetime: 4.7161 years
Did either of these change by more than 5%? No
At the SURFACE, list all species that changed by 10% or more: PAN, ACET, R4N2
Comments on SURFACE differences: ACET generally decreases 10-50%, strongest decreases over the oceans due to elimination of the (incorrect) ocean source. Over continental regions, the largest changes are away from terrestrial acetone sources. There are smaller relative changes over the main continental emission regions. PAN decreases by 10-25% over most of the NH oceans, but the absolute differences are very small due to low surface PAN mixing ratios in these regions (< 30 pptv). Weak decreases for R4N2 in a couple spots.
At 500 hPa, list all species that changed by 10% or more: ACET, R4N2
Comments on 500 hPa differences: ACET decreases of 10-25% over many regions at 500hPa. Weak decreases for R4N2 in a couple spots.
In the ZONAL MEAN differences, list all species that changed by 10% or more: ACET, PAN
Comments on ZONAL MEAN differences: Changes exceeding 10% for ACET and PAN, consistent with the above.
In the EMISSION RATIO maps, list all species that changed by 10% or more: ACET
Comments on EMISSION RATIO differences: Changes as expected based on emission updates.
