In Phase 2, we aim to provide access to four well-defined, community-supported model configurations for a wide range of scientific and operational applications.
 

 1 

Century-scale ensembles
Climate change, CMIP, IPCC, decadal predictions
ICON atmosphere & ocean; carbon cycle (optional) 

 2 

Millennial-scale ensembles
Paleo-climate, long-term futures, education
Atmosphere, ocean, carbon cycle, ice sheets, solid Earth

 3 

Air-quality simulations
Chemistry, aerosols, near-surface pollution
Atmosphere chemistry/aerosol (+ ocean optional)

 4

km-scale-resolution simulations
Realistic circulation, extremes, km-scale atmosphere & ocean
Atmosphere (≤10 km), ocean (≤ 5 km), no parameterization
