The CMAM model contribution to CCMI-2022 set of experiments defined by the SPARC- and IGAC-supported Chemistry-Climate Model Initiative.

The CCMI-2022 set of model experiments focus on the stratosphere, with the goals of providing updated projections of the future evolution of ozone and improving our understanding of chemistry-climate interactions and how they are represented in models.

The CMAM chemistry-climate model is run by the modelling team at CCCma (Canadian Centre for Climate Modelling and Analysis, Environment and Climate Change Canada) and configured to follow forcings as laid out in the CCMI2022 founding document (Plummer et al., 2021)

SPARC and IGAC projects coordinate international research in atmospheric chemistry. SPARC (Stratosphere-troposphere Processes And their Role in Climate) is a core project of the World Climate Research Programme (WCRP). IGAC is the International Global Atmospheric Chemistry which currently operates under the umbrella of Future Earth.
