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).
