Coupling GEOS-Chem with NCAR models

On this page, we provide information about ongoing efforts to interface GEOS-Chem with Earth System Models maintained by the National Center for Atmospheric Research (NCAR).

Please see our Coupling GEOS-Chem with other models wiki page for information about projects to interface GEOS-Chem with other Earth System Models.

NCAR-GEOS-Chem meeting

Daniel Jacob wrote:

Several of us were at a NCAR-GEOS-Chem meeting (July 30-31, 2018) to resolve issues in the on-line coupling of GEOS-Chem with CESM2 and WRF, and to lay the basis for integrating GEOS-Chem into the next generation of NCAR models (SingleTrack). The meeting was very productive, with a lot of interest from NCAR scientists, and laid the basis for strong collaboration in the future. You can access the meeting presentations here:

If you are interested in contributing to development and testing of the CESM-GC and WRF-GC models I encourage you to contact the lead developers, Seb Eastham (for CESM-GC) and Tzung-May Fu (for WRF-GC).

CESM-GC

Lead Developer:

• Sebastian Eastham (MIT)
• Thibaud Fritz (MIT) (GitHub @fritzt)
• Haipeng Lin (Harvard) (GitHub @jimmielin) - HEMCO with CESM-GC Developer

Validation

TBD

Known issues

TBD

WRF-GC

Website

• wrf.geos-chem.org

Lead Developers:

• Tzung-May Fu (SUSTech) (GitHub @tmayfu)
• Xu Feng (PKU) (GitHub @fengx7)
• Haipeng Lin (Harvard; formerly PKU) (GitHub @jimmielin)

Validation

• A paper describing WRF-GC, WRF-GC (v1.0): online coupling of WRF (v3.9.1.1) and GEOS-Chem (v12.2.1) for regional atmospheric chemistry modeling – Part 1: Description of the one-way model (Lin et al., 2020) includes a East China PM2.5 simulation for initial validation of the model. A more detailed paper by Xu Feng at PKU will include two-way coupling (i.e. feedback of GEOS-Chem chemistry to WRF meteorology) and further model validation.
• Please contact Tzung-May Fu, WRF-GC model scientist, for access to private beta and more information about the model.
• Xu Feng is the current lead maintainer of the model, including scientific development of the two-way (with feedback) coupling of WRF and GEOS-Chem. Haipeng Lin will serve as point-of-contact for GEOS-Chem compatibility and leads the development of the nested-Grid version.

Known issues

• A regional refinement nested-Grid version of WRF-GC is in technical validation and nearing final stages of development. Please contact us to express interest. A release is anticipated for Late 2020.
