Revision as of 19:33, 26 March 2008
NOTE: The order in which various updates enter into the standard GEOS-Chem code may differ than what is listed here, depending on circumstances.
v8-01-04 ??
Also adds:
v8-01-03 ??
Also adds:
- EPA/NEI99 California transport sector fix
- Updated MEGAN annual emission factors for isoprene
- PERHAPS -- Updated mercury simulation (cf. Noelle, Elsie, Chris, Sarah Strode, etc.)
v8-01-02 ??
Also adds:
- May Fu's updated chemistry mechanism ???
- New scale factors for anthropogenic emissions (cf. Aaron van Donkelaar)
v8-01-01
PUBLIC RELEASE scheduled for April 2008
Contains everything in v7-04-13, with the following additions:
- This is the first version to be compatible with the GEOS-5 met fields.
1-Year Benchmarks
Description
- Results from v8-01-01 1-year benchmark simulation (w/ GEOS-5 met) are contained in the directory:
/pub/geos-chem/1yr_benchmarks/v7-04-12/geos5/2005/Run
- This benchmark uses the same input conditions and emissions as v7-04-13. The only difference is that this benchmark was done w/ GEOS-5 met and v7-04-13 was done w/ GEOS-4 met.
The 3 models compared (and their colors on the plots) were:
| Color | Quantity Plotted | Met Field Type | Lightning algorithm |
|---|---|---|---|
| Red | v7-04-12 Run2 | GEOS-4 4x5 | near-land w/ OTD-LIS regional scaling |
| Green | v7-04-13 | GEOS-4 4x5 | updated non-near-land w/ OTD-LIS local scaling |
| Blue | This model version | GEOS-5 4x5 | updated non-near-land w/ OTD-LIS local scaling |
| Black | Observations |
Results
Release Notes
- We have implemented the fix for the last year of GFED2 biomass emissions, (which is now 2006) into v8-01-01.
v7-04-13
BETA RELEASE November 2007
Contains everything in v7-04-12, with the following additions:
- Offline H2/HD simulation (cf. Lyatt Jaegle et al)
- Bug fix in "smvgear.f" -- due to a design flaw, you could have a situation where you could have negative or zero tracer in a box even if the global & local error criteria were satisfied. If this condition is encountered, we now revert to the concentrations at the end of the previous internal timestep, and then reduce the internal timestep and try again until we get convergence.
- Bug fix -- replace GEMISNOX w/ module arrays to avoid common block errors in lightning & aircraft NOx emissions
- Bug fix -- cap variable tropopause at 200hPa for polar regions (90S-60S and 60N-90N)
- Lee Murray's local lightning redistribution of lightning flashes
- Minor bug fixes for GCAP and diagnostics
1-Year Benchmarks
Description
- Results from 1-year benchmark simulation (w/ GEOS-4 met) are contained in the directory: <tt/pub/geos-chem/1yr_benchmarks/v7-04-12/geos4/2005/Run</tt>
- This benchmark uses the same input conditions and emissions as v7-04-12-Run2, except for the updated lightning emissions as described above.
The 3 models compared (and their colors on the plots) were:
| Color | Quantity Plotted | Met Type | Lightning algorithm |
|---|---|---|---|
| Red | v7-04-12 Run1 | GEOS-4 4x5 | ancient |
| Green | v7-04-12 Run2 | GEOS-4 4x5 | near-land w/ OTD-LIS regional scaling |
| Blue | This model version | GEOS-4 4x5 | updated non-near-land w/ OTD-LIS local scaling |
| Black | Observations |
Results
Release Notes
- The maximum year for GFED2 emissions in this version is 2005. If you want to use the 2006 emissions you will have to edit the source code module "gfed2_biomass_mod.f".
v7-04-12
BETA RELEASE October 2007
We have already done the following 1-year benchmark simulations:
