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 from the SiB3 biospheric model will be a new option. | Included in GEOS-Chem v10-01 |
Update anthropogenic CO2 fluxes | Implement anthropogenic (fossil fuel combustion) CO2 emissions with higher temporal resolution and perhaps higher spatial resolution. | Included in GEOS-Chem v10-01 |
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. | Included in GEOS-Chem v10-01 |
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. | Work completed and described in Fisher et al., submitted to GMDD April 2017. To be included in v11-02 or later. |
CO-CO2-CH4 simulation | Merge into a single offline simulation for the standard model. | In Development Beata Bukosa |
Improved satellite diagnostic | Implement more flexible diagnostic for saving out XCO2 and other satellite-relevant parameters. |
