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. To be 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. To be 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. To be 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.
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.
