<br />
This page contains information about the carbon dioxide (CO<span><sub>2</sub>) simulation in GEOS-Chem.<br />
<br />
== Overview ==<br />
<br />
The current GEOS-Chem CO<span><sub>2</sub> simulation was developed by Parv Suntharalingam, now at the University of East Anglia (Suntharalingam et al., 2003; 2004). A major update to the CO<span><sub>2</sub> simulation has been developed by Ray Nassar 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.'''''<br />
<br />
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 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 NMHCs. This will make GEOS-Chem the only model to account for the chemical production of CO<span><sub>2</sub>. This chemical source is an online implementation of the concept described in Suntharalingam et al. (2005), now with seasonality, updated year-specific numbers and other modifications.<br />
<br />
The full GEOS-Chem CO<span><sub>2</sub> update was applied to v8-02-01 (along with some patches). It is now undergoing testing and shuold be publicly available in the next GEOS-Chem release (v8-03-02). The model update will be accompanied by an update to the GEOS-Chem online manual. The references below are cited in the updated code's comments and online manual. <br />

<hr />
<div>Hi,<br />
<br />
I’m trying to run adjoint code (v6-2-5, full chem) at some machine<br />
<br />
but I stuck on the allocation error.<br />
<br />
The system support 64-bit ifort (Linux) and I tested the stacksize and KMP size for many times (there should be enough memory).<br />
and there is no job scheduler, so I submit the job by typing "./scriptfile"<br />
<br />
And I got across this message,<br />
<br />

Have you experience this kind of error?<br />
Changing memory setting doesn't help and the array(s) are not big.<br />
