The CRESCENDO project, led by Prof Colin Jones from the National Centre for Atmospheric Science (NCAS) and the University of Leeds facilitates a coordinated European contribution to the 6th Coupled Model Intercomparison Project (CMIP6) where the climate research community compares a range of International Earth System Models using common sets of experimental protocols, to improve our knowledge of the Earth’s climate processes and provide the best possible future projections to governments and decision-makers. CRESCENDO in particular better informs a number of key Model Intercomparison Projects (MIPs) where biogeochemical and aerosol components are of critical importance to delivering realistic future projections. Such components include: the terrestrial and marine carbon cycle, vegetation processes, permafrost, atmospheric chemistry and aerosols.

CRESCENDO is structure in 5 Research Themes (RTs) plus a Project management work package. Each RT addresses a science or dissemination goal of the project. RTs are further divided into work packages (WPs) allowing increased research focus.

CRESCENDO brings together 7 European Earth System Modelling (ESM) teams and 3 European Integrated Assessment Modelling (IAM) groups, with experts in ESM performance evaluation, ESM future projection analysis, climate impacts, regional downscaling and science communication, representing 10 European countries.
