Overview
CHEMISTRY RELEASE -- ABOUT TO BE RELEASED!!
Will contain everything in v8-01-04 plus the following:
- Glyoxal chemistry (May Fu) (NOTE: This is an option which is turned off by default)
- Updated J(O1D) cross sections (Lin Zhang)
- Updated reaction rates (Jingqiu Mao, Dylan Millet, Palmer group @ U. Edinburgh)
- HO2 uptake (Lyatt Jaegle)
- Updated dust single scattering albedo (Randall Martin)
1-year benchmarks
Run0
Three GEOS-Chem model versions were compared to each other:
Color | Quantity Plotted | Met Field Type | Anthro Emissions | Photolysis | Chemical Mechanism | Annual Mean OH [105 molec/cm3] |
---|---|---|---|---|---|---|
Red | v8-01-04 Run1 | GEOS-5 4x5 version 5.0.1 w/ "quick fix" for optical depth spinup: 2005 run: 2005 |
GEIA/Piccot EDGAR emissions EMEP European emissions BRAVO Mexican emissions David Streets 2006 emissions CAC Canadian emissions EPA/NEI99 with ICARTT fix EDGAR ship emissions ARCTAS ship SO2 emissions Anthro scale year 2005 |

SUMMARY:
- v8-01-04 Run2 vs. v8-01-04 Run1 is a clean comparison between the GEOS-5.0.1 and GEOS-5.1.0 met products.
- v8-02-01 Run0 vs. v8-01-04 Run2 is a clean validation for the new chemistry mechanism, photolysis rates, and other updates that were added into v8-02-01.
- All runs used the same:
- A.T.E. Algorithm = RPMARES
- Advection routine: "new" tpcore
- Biogenic emissions: "new" MEGAN AEF's for isoprene
- GFED2 biomass emissions
- Aircraft NOx emissions
- Approximate random cloud overlap option in photolysis
