Opportunities for Collaboration

Opportunities and Partnerships

ACOM conducts collaborative research focusing on two major scientific challenges, Air Quality Prediction Research and Interactions between Chemistry and the Climate/Weather System. The work is conducted in partnership with other entities within NCAR, and with other members of the wider atmospheric chemistry community.

Model grids used in the spectral element version of the NCAR Community Atmosphere Model (CAM-SE).

Multi-Scale Infrastructure for Chemistry Modeling (MUSICA)

Field Missions and Data Archive

Data collection in the field.

Chemical Forecasts

Generated daily with WACCM, CAM-Chem, and WRF-Chem.
