Development Priorities
| Priority | Description | Status |
|---|---|---|
| Update biospheric CO2 fluxes | Currently based on CASA (neutral biosphere) output for one particular year and a climatology of net terrestrial exchange. Running with year-specific fluxes or coupling a biospheric carbon model to GEOS-Chem will be explored. | To be included in GEOS-Chem v9-02 |
| Update anthropogenic CO2 fluxes | Implement anthropogenic (fossil fuel combustion) CO2 emissions with higher temporal resolution and perhaps higher spatial resolution. | To be included in GEOS-Chem v9-02 |
| Update ocean CO2 fluxes | Currently using Takahashi et al. (2009) which gives too weak of a global sink. Look into possibilities for scaling or improved ocean fluxes from another source. | |
| Tagged CO simulation | Improve treatment of secondary production of CO from VOC oxidation. Currently just scale emissions. Modify code to apply photochemical production rates archived from a full chemistry simulation. | |
| CO-CO2-CH4 simulation | Merge into a single offline simulation for the standard model. | |
| Improved satellite diagnostic | Implement more flexible diagnostic for saving out XCO2 and other satellite-relevant parameters. |
