The Atmospheric Chemistry Observations and Modeling (ACOM) Laboratory at NCAR plans to develop a new community modeling infrastructure jointly with different interested groups in the world. MUSICA – the Multi-Scale Infrastructure for Chemistry and Aerosols – will become a computationally feasible global modeling framework that allows for the simulation of large-scale atmospheric phenomena, while still resolving chemistry at emission and exposure relevant scales (down to ~4 km within the next 5 years). MUSICA will eventually replace and extend the current separate community chemistry modeling efforts at NCAR (e.g. WACCM, CAM-Chem, WRF-Chem), paralleling other activities at NCAR to streamline and unify model development.

The objectives of the MUSICA kick-off meeting are to:

  • Engage the participation of the community at an early stage in the development of a new unified model for the global to local prediction of air quality and investigations of the role of chemistry in weather and climate.
  • Establish partnerships on the MUSICA development and identify overlap and collaborative opportunities with other model development initiatives.
  • Determine the community expectations of a unified model
  • Brief the community on the future of chemistry modeling as part of NCAR’s integrated earth system model development plans.
  • Identify opportunities for scientific collaborations in the areas of chemical prediction and projection, assessing the impacts and risks of air pollution and development of mitigation strategies in a Whole Atmosphere Approach.
  • Discuss the co-development of a framework for model evaluation, data assimilation and model diagnostics in conjunction with the development of MUSICA.


 We expect to have a White Paper/Action Plan developed as part of this meeting.
