Unresolved issues from GEOS-Chem v9-02
These issues were first identified in GEOS-Chem v9-02.
Issue | Reported by | Affects | Status |
---|---|---|---|
Potential issue with soil NOx in GCAP simulation | GEOS-Chem Support Team | Full-chemistry simulations using GCAP meteorology and ship emissions | OPEN. We are continuing to look at this issue and hope to have a fix for GEOS-Chem v10-01. |
Potential parallelization problems in TOMAS "ND60" diagnostic | Sal Farina GEOS-Chem Support Team |
Simulations using TOMAS aerosol microphysics | OPEN. This issue only affects the ND60 diagnostic output itself, but not the tracer concentrations computed by TOMAS. For this reason, we are moving forward with the TOMAS benchmarks for GEOS-Chem v9-02. |
Isoprene emissions are lower when using GEOS-FP meteorology | Dylan Millet (U. Minnesota) | Simulations using biogenic emissions | OPEN. This does not necessarily indicate a flaw in GEOS-Chem, but is a matter of active research. It is known that the surface temperatures in GEOS-FP are biased low compared to GEOS-5, which is likely causing this issue. |
Soil NOx emissions are lower when using GEOS-FP meteorology | Prasad Kasibhatla (Duke) | Simulations soil NOx emissions | OPEN. This does not necessarily indicate a flaw in GEOS-Chem, but is a matter of active research. It is known that the surface temperatures in GEOS-FP are biased low compared to GEOS-5, which is likely causing this issue. |
Need to adjust pulsing threshold when using GEOS-FP meteorology | Patrick Kim (Harvard) Karen Yu (Harvard) |
Simulations soil NOx emissions | OPEN. This does not necessarily indicate a flaw in GEOS-Chem, but is a matter of active research. The threshold for pulsing simulations will have to be adjusted so that GEOS-FP nested-grid simulations at 0.25° x 0.3125° yield emissions consistent with the global 4° x 5° and 2° x 2.5° simulations. |
O3 completely removed at Shanghai grid box with GEOS-FP 4x5 simulation | Patrick Kim (Harvard) GEOS-Chem Support Team |
Full-chemistry with ship emissions using GEOS-FP 4° x 5° met | RESOLVED.
|
Regional biofuel emissions may be neglected when using RETRO or RCP emissions | Chris Holmes (UC Irvine) | Simulations using global and regional biofuel emissions | RESOLVED. |
Bug in tagged Hg emissions | Carey Friedman (MIT) | Tagged Hg simulations | RESOLVED. |
Bug in ship CO emissions | Chris Holmes (UC Irvine) | Simulations using EMEP ship emissions | RESOLVED.
|
Bug fixes in biofuel_mod.F and emfossil.F | Christoph Keller (Harvard) | Simulations using biofuel and anthropogenic emissions | RESOLVED.
|
Ozone over the eastern US is too high when using the Olson 2001 land map | Patrick Kim (Harvard) Natasha Goss (Harvard) |
Full-chemistry simulations | RESOLVED.
|
Incorrect value of molecular weight for the PROPNN tracer in input.geos | Jenny Fisher (Wollongong) | Full-chemistry, SOA, and aerosol microphysics simulations. | RESOLVED.
|
Bug in determining when to use TOMS O3 columns | GEOS-Chem Support Team | Full-chemistry, SOA, and aerosol microphysics simulations. | RESOLVED.
|
Timeseries diagnostics need to be updated to allow for more transported tracers | Prasad Kasibhatla (Duke) | All simulations, especially full-chemistry | RESOLVED.
|
Bug in FAST-J acetone photolysis pressure dependency | Jingqiu Mao (Princeton) GEOS-Chem Support Team |
All full-chemistry simulations (including SOA, dicarbonyl, and aerosol microphysics options) | RESOLVED.
|
Missing error checks for RCP in input_mod.F | Jenny Fisher (U. Wollongong) | Simulations using the RCP future scenarios | RESOLVED.
|
Bug fixes and updates for the tagged CO simulation | Jenny Fisher (U. Wollongong) | Tagged CO simulations | RESOLVED.
|
Avoid seg faults when starting simulations at times other than 00 UTC | Chris Holmes (UC Irvine) | Simulations using the BRAVO anthro emissions and ARCTAS SO2 ship emissions | RESOLVED.
|
Compilation error in ND63 diagnostic | Cenlin He (UCLA) | Simulations using the ND63 PARANOX diagnostic, using certain IFORT compiler versions. | RESOLVED.

Unresolved issues from GEOS-Chem v9-01-03
These issues were first identified in GEOS-Chem v9-01-03.
Issue | Reported by | Affects | Status |
---|---|---|---|
Issues with Intel Fortran Compiler (IFORT) version 12 | GEOS-Chem Support Team | Some users have reported issues when migrating from IFORT 11 to IFORT 12. | OPEN. Switching compiler versions seems to help. |
Negative ship emissions caused by PARANOX plume model | Geert Vinken (Eindhoven) | Full-chemistry simulations using ship emisisons | RESOLVED. Negative O3 values from ship emissions are now treated as a loss via dry deposition, rather than being set to zero.
|
Bug fix in hdf_mod.F | Sajeev Philip (Dalhousie) | Timeseries diagnostics saved out to HDF5 format | RESOLVED.
|
Bug fixes for tagged CO simulation | Jenny Fisher (Wollongong) | Tagged CO simulations | RESOLVED.
|
Bug fix in nei2005_anthro_mod.F | Sajeev Philip (Dalhousie) | Nested-grid simulations using NEI 2005 emissions | RESOLVED.

Unresolved issues from GEOS-Chem v9-01-02
These issues were first identified in GEOS-Chem v9-01-02.
Issue | Reported by | Affects | Status |
---|---|---|---|
Numerical noise in ISORROPIA II | GEOS-Chem Support Team Shannon Capps (Georgia Tech) |
Full-chemistry and offline aerosol chemistry simulations | OPEN. We are contemplating replacing ISORROPIA II by another package in a future version of GEOS-Chem. |
RETRO anthropogenic ethane emissions are too low | Bess Corbitt (Harvard) | Full chemistry simulations | RESOLVED. We have replaced the RETRO ethane emissions with the ethane emissions from Yaping Xiao's offline simulation.
|
High bias in nighttime ground-level aerosol | Sajeev Philip (Dalhousie) | All full-chemistry and aerosol simulations using GEOS-5? | RESOLVED. Sajeev Philip implemented this fix.
|
Mis-indexing bug in emep_mod.F | GEOS-Chem Support Team | Offline simulations only | RESOLVED.
|
Bug in nei2005_anthro_mod.F | GEOS-Chem Support Team | Offline simulations only | RESOLVED.
|
Parallelization problem in LINOZ | Prasad Kasibhatla (Duke) | Full-chemistry and tagged Ox simulations | RESOLVED.
|
Dependency between dry deposition and soil NOx emissions | GEOS-Chem Support Team Rynda Hudman |
Full-chemistry simulations | RESOLVED. This is historical baggage dating back to the earliest versions of GEOS-Chem. The implementation of the new updated soil NOx emissions algorithm has corrected this issue.

Issue | Reported by | Affects | Status |
---|---|---|---|
KPP may cause run to exit with error | GEOS-Chem Support Team | Full-chemistry simulations | OPEN. This will likely be resolved when FLEXCHEM is implemented into GEOS-Chem. |

---|---|---|---|
Surface ozone over the US is 5-10 ppb too high. | Daniel Jacob (Harvard) | Full-chemistry simulation | Improved treatment of isoprene nitrates chemistry in GEOS-Chem v8-03-02 has resulted in positive bias in the ozone simulation over the US.
