The Atmospheric Chemistry Observations and Modeling (ACOM) Laboratory at NCAR together with the atmospheric chemistry community is developing a new community modeling infrastructure. 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.

Are you looking for the MuSICA ecosystem model? The INRAE Multi-layer Simulator of the Interactions between vegetation Canopies and the Atmosphere (MuSICA) is primarily an ecosystem model focused on exchange between the atmosphere and terrestrial vegetation.

NEWS & UPDATES


MUSICA vs WRF-Chem - a comparison.

A monthly MUSICA Tutorial Series started November 12, 2021 - see the Tutorial Website for more information. 

MUSICAv0 with regional refinement over the conterminous U.S. is now available in CESM2.2. More information on MUSICAv0 is on the MUSICA-V0 webpage.  Community Simulation: The standard configuration of MUSICAv0 has been run for 2012-2013 and the output is available for download from the DASH repository.

Learn more about MUSICA Working Groups on the MUSICA Governance page.

The MUSICA Kick-Off meeting was held at NCAR from 21-22 May, 2019. Presentations from this meeting are available from the meeting website.
