Revision as of 15:59, 27 July 2018
GEOS-Chem v11-02-final will also carry the designation GEOS-Chem 12.0.0. We are migrating to a purely numeric versioning system in order to adhere more closely to software development best practices. For a complete description of the new versioning system, please see our GEOS-Chem version numbering system wiki page.
On this page we list information about the various
anthropogenic emissions inventories available for use w/ GEOS-Chem v8-02-03 and higher versions.

RETRO
RETRO anthropogenic VOC emissions are the recommended default for anthropogenic VOC emissions. The RETRO inventory has improved temporal and spatial resolution and a more inclusive suite of speciated NMVOCs than many of the other optional inventories.
C2H6
This update was included in v11-02f (approved 17 May 2018).
Global fossil fuel and biofuel emissions of C2H6 for 2010 have are included in GEOS-Chem v11-02. These C2H6 emissions will overwrite C2H6 emissions from RETRO and Xiao et al. (2008).

GEIA/Piccot
Previously, this was the baseline anthropogenic emissions inventory in GEOS-Chem.
Description from Wang et al [1998]:
A global NOx emission inventory (21 Tg N/yr) from fossil fuel combustion has been compiled by the Global Emission Inventory Activity [Benkovitz et al 1996] with a 1° x 1° resolution....
Our global CO emission inventory includes 390 TG CO/yr from fossil fuel combustion and industrial activities and 130 Tg CO/yr from wood fuel burning. This inventory has a resolution of 1° x 1° and is aseasonal....
We adopted the country-by-country inventory of Piccot et al [1992] for emissions of paraffins (45 Tg C/yr) and olefins (18 Tg C/yr) from fossil fuel combustion and industrial activity. The emissions within each country were distributed on the basis of population density using a 1° x 1° population map [Benkovitz et al 1996]. The Piccot et al inventory gives no information on the speciation of paraffins and olefins; a speciation of emissions for the United states is, however, available from NAPAP [Middleton et al 1990]....On the basis of [additional data from Harvard Forest], we modify the NAPAP apportionment of paraffins....Assuming the NHMC speciation for the United States to be globally representative, we deduce global emission rates of 6.3 Tg C/yr of Ethane, 6.8 Tg C/yr of propane, 30 Tg C/yr of >=C4 alkanes, 1.0 Tg C/yr of acetone, 1.0 Tg C/yr of higher ketones, and 10.4 Tg C/yr of >=C3 alkenes.

Regional inventories
These inventories (which are now compatible with the HEMCO emissions component) can be used to "overwrite" the global emissions inventories in specific regions of the world. We recommend that you turn on the regional emissions (e.g. BRAVO, CAC, EPA/NEI, EMEP, etc.), which will override the default underlying global emissions (e.g. EDGAR).
To select the regional emissions inventories, follow the steps below.
- GEOS-Chem v10-01 and newer versions: Modify the HEMCO_Config.rc file.
- GEOS-Chem v9-02 and earlier versions: Modify the EMISSIONS MENU section of the input.geos file. For detailed instructions, please see Section 5.2.1.5 of the GEOS-Chem Users' Guide.

Annual scale factors for anthropogenic emissions inventories
NOTE: In GEOS-Chem v10-01 and higher versions, all emission scale factors are applied via the HEMCO emissions component.
Please see our Scale factors for anthropogenic emissions wiki page for the latest information about scale factors for anthropogenic emissions inventories used in GEOS-Chem.
The " => Scale to (1985-2005)" option in input.geos will scale all anthropogenic emissions to the year that you select, unless data for that year exists. If you enter a negative number (recommended), emissions will be automatically scaled to the closest-to-simulation year and/or the best base year is selected when several are available in one inventory (like EMEP). It is recommended to set this field to -1 or 2006 for simulations after 2005, so that all inventories are scaled to 2005, and STREETS 2006 is used in SE ASIA.
Here is a brief explanation from van Donkelaar et al., ACPD, 8, 4017-4057, 2008:
We scale all regional and global inventories from their respective base year to 2003, the last year of available statistics, unless its base year is after 2003. Our approach follows Bey et al. (2001) and Park et al. (2004). Emissions are scaled according to estimates provided by individual countries, where available. These countries/regions include the United States, Canada, Japan and Europe. NOx emissions of remaining countries are scaled proportional to changes in total CO2 emissions. SOx emissions are similarly scaled to solid fuel CO2 emissions and CO emissions to liquid fuel CO2 emissions. CO2 emission data are obtained from the Carbon Dioxide Information Analysis Center (CDIAC).
Note that the scale factor have been updated since that paper to go up to 2005, and are based on REAS data now for South East Asia:
Relative changes in the REAS inventory (Ohara et al., ACP, [2007], http://www.jamstec.go.jp/frsgc/research/d4/reas_h_a.html) over East Asia have been used. This should be a good improvement as REAS emissions are gridded, rather than national scale emissions, giving us much better spatial detail. Also, these scalars are now based on actual NOx, SOx and CO emission estimates, not strictly an assumed proportionality between total, solid and liquid CO2 emissions.
Seasonal scale factors for anthropogenic emissions inventories
Seasonal scale factors are described on the Scale factors for anthropogenic emissions wiki page.
Diurnal variation for anthropogenic NOx emissions
The diurnal variation for NOx is described on the Scale factors for anthropogenic emissions wiki page.

Previous issues that are now resolved
Anthropogenic ethane emissions are too low
This update was tested in the 1-month benchmark simulation v9-01-03i and approved on 26 Mar 2012.
In addition to RETRO anthropogenic ethane emissions being too low, Emily Fischer found that ethane emissions in the EPA/NEI2005, Streets, and EMEP regional inventories are also too low. Therefore, these regional ethane emissions should not overwrite the global anthropogenic ethane emissions provided by Yaping Xiao. This update is slated for implementation into GEOS-Chem v9-01-03, as part of the update to replace RETRO C2H6 emissions with emissions from the offline C2H6 simulation.
Prevent negative emissions over Canada
This update was tested in the 1-month benchmark simulation v9-02m and approved on 30 Jul 2013. This update is included in Adjoint v35.
In GEOS-Chem v10-01 and newer versions, CAC emissions are now handled by the HEMCO emissions component.
The information below is now obsolete, but we shall leave it here for reference.

- I think I found a nasty bug in CAC emissions. I am getting negative emissions, for 200611 for all anthropogenic species in Canada (standard code v9.1.3). I think this is related to line 413, where some linear interpolation is performed, assuming that 2005 emissions will be greater than 2002 emissions in every grid box.
- We should set the emissions to 0 when 2002 exceeds 2005 by more than a factor of three.
- Anyway, the bug will get worse and worse after 2006.
Christoph Keller wrote:
- I didn't check it quantitatively, but this makes sense!
- What if we add a simple where statement after line 413:
WHERE ( GEOS_1x1 < 0d0 ) GEOS_1x1 = 0d0 END WHERE

- Yes this would work. I haven't checked the nested simulation. There may be an error there too.
- Note this will only affect 2006 and 2007
