The original GEOS-Chem CO<span><sub>2</sub> simulation was developed by Parv Suntharalingam (Suntharalingam et al., 2003; 2004), now at the University of East Anglia.  A major update to the CO<span><sub>2</sub> simulation has been developed by Ray Nassar (now at Environment Canada) and Dylan B.A. Jones of the University of Toronto (Nassar et al., 2010).  This update was delivered to the GEOS-Chem software development team at Harvard on 2010 April 1.'''''

The update retains the original six CO<span><sub>2</sub> fluxes: fossil fuel, ocean exchange, biomass burning, biofuel burning, balanced terrestrial exchange (CASA) and net annual terrestrial exchange.  New inventories are available as options for some of these fluxes and other new fluxes have been added such as CO<span><sub>2</sub> emissions from international shipping and aviation. There is also now an optional feature to include CO<span><sub>2</sub> production from the oxidation of CO, CH<span><sub>4</sub> and NMVOCs. This chemical source concept was first highlighted by Enting and Mansbridge (1991). Although a few attempts have been made by other groups in the past, this implementation will make GEOS-Chem the only 3-D global model in current use to account for the chemical production of CO<span><sub>2</sub>.  The GEOS-Chem implementation uses an approach similar to that described in Suntharalingam et al. (2005), with some updated year-specific numbers and some other modifications described in Nassar et al. (2010).

The full GEOS-Chem CO<span><sub>2</sub> update was applied to and tested with v8-02-01 (along with some patches). It is now publicly available in GEOS-Chem release v8-03-02 and later versions, along with an update to the GEOS-Chem online manual. The references below are cited in the updated code's comments and online manual, and include the new CO<span><sub>2</sub> simulation description paper Nassar et al. (2010).

In Feb 2010, the CDIAC fossil fuel emissions inventory was updated.  Files containing annual and monthly emissions of CO2 are now available for the years 1979-2009.

== Validation ==
+
 
+
The updated CO<span><sub>2</sub> simulation will be incorporated into GEOS-Chem v8-03-02. In Nassar et al. (2010) model comparisons are made with GLOBALVEIW-CO2 (http://www.esrl.noaa.gov/gmd/ccgg/globalview/co2/co2_intro.html) and CONTRAIL (Comprehensive Observation Network for TRace gases by AIrLiner) measurements.  In other work, the CO<span><sub>2</sub> simulation has also been compared with aircraft observations from the HIAPER Pole-to-Pole Observations (HIPPO) campaigns of 2009 (Wofsy et al., 2010).
+
 
+
== Restart Files ==
+
 
+
=== Description ===
+
 
+
Some single-tracer restart files are available:
+
 
+
;restart.20000101:CO2 restart file for GEOS4 (30 levels) on date 2000-01-01
+
;restart.20040101:CO2 restart file for GEOS5 (47 levels) on date 2004-01-01
+
 
+
These two restart file have uniform CO<span><sub>2</sub> values of 367.2 ppm for 2000-01-01 and 375.0 ppm for 2004-01-01, which are reasonable estimates of the global mean, but not realistic in the global distribution.  Spinning up for one year will result in a realistic distribution in terms of both the global mean value and gross features (latitudinal gradient and seasonal/diurnal cycle) but accurate work will require adjusting or calibrating the restart file with actual measurements for the start of your run. The method of calibration using the sparse in situ measurements and/or satellite observations can be an active area of research on its own, so determining the approach to this is left to the user.
+
 
+
=== Downloading ===
+
 
+
You can use the Git version control software to download GEOS-Chem run directories containing the above-mentioned restart files and other relevant input files (e.g. <tt>input.geos</tt>).
+
 
+
To download the GEOS-4 (30 levels) run directory, use this command:
+
 
+
git clone git://git.as.harvard.edu/bmy/GEOS-Chem-rundirs/2x2.5/geos4/CO2_run
+
 
+
To download the GEOS-5 (47 levels) run directory, use this command:
+
 
+
git clone git://git.as.harvard.edu/bmy/GEOS-Chem-rundirs/2x2.5/geos5/CO2_run

=== Monthly CDIAC CO2 emissions ===
 
 
Although GEOS-Chem v8-03-02 will be released with the functionality to run with monthly fossil fuel CO<span><sub>2</sub> emissions from CDIAC (R.J. Andres), the inventory files most likely will not be released until a later date, when the submitted paper Andres et al. (2010) is at a sufficient stage.  Until then, annually-averaged fossil fuel CO<span><sub>2</sub> emissions must be selected in the input.geos file.

This page contains information about the carbon dioxide (CO2) simulation in GEOS-Chem.

Overview

The original GEOS-Chem CO2 simulation was developed by Parv Suntharalingam (Suntharalingam et al., 2003; 2004), now at the University of East Anglia. A major update to the CO2 simulation was completed in 2010 by Ray Nassar and Dylan B.A. Jones of the University of Toronto (Nassar et al., 2010). The latest update to the CO2 simulation was developed by Ray Nassar (now at Environment Canada) and appears in GEOS-Chem v10-01, which was released on 2015 May 1.
