Regional Downscaling GCM (Sweden represented by ~7 squares) RCM (Sweden represented by >150 squares) Regional climate models offer much greater detail at local and regional scales. This is vital to improve vulnerability, impact and adaptation planning, particularly with regards to extreme events etc.
CORDEX Scientific Vision To advance and coordinate the science and application of regional climate downscaling through global partnerships Goals: To better understand relevant regional/local climate phenomena, their variability and changes, through downscaling. To evaluate and improve regional climate downscaling models and techniques To produce coordinated sets of regional downscaled projections worldwide To foster communication and knowledge exchange with users of regional climate information

CORDEX disseminates downscaled model data via the Earth System Grid Federation (ESGF)
CORDEX Data requirement Core Tier 1 Tier 2 Monthly and seasonal [ESGF] Daily [ESGF] Higher frequency (sub-daily) [Modelling centre]
CORDEX Scientific Challenges Added value Internal variability & added value as functions of scale; Bias correction uncertainties and consistency; User-oriented metrics Human element Coupling of regional climate and coastal megacities; Bridging with urban parameterisation development; Land use change Coordination of regional coupled modelling Ocean-ice-atmosphere; Lakes; Dynamic land surface; Cryosphere; Natural fires; Atmospheric chemistry; Carbon cycle; Aerosols; Marine biogeochemistry Precipitation Convective systems; Coastal storm systems; MJO/Monsoon Local wind systems Wind storms; Strong regional winds; Wind energy
Flagship Pilot Studies (FPS) Five now established: EUR+MED: Convective phenomena EUR: Impact of land use changes S. AM: Extreme precipitation events. MED: Role of natural and anthropogenic aerosols MED: Role of air-sea coupling and small-scale ocean processes More recent round of FPS proposals under review.
CORDEX Linkages A CMIP6 Diagnostic MIP How can we assess future climate changes given climate variability, predictability and uncertainties in scenarios? IPCC Interest CORDEX Coordinated Output for Regional Evaluations (CORE) Succinct set of downscalings for IPCC assessments
CORDEX Community ESGF CST NHMS / Users What about issues related to understanding / interpretation of model performances, behavior? Model biases?
CORDEX Community ESGF CST What is the best approach to communicate the information? Peer-reviewed publication? Technical Reports? NHMS / Users
Constraints & gaps within CORDEX Lack of resources; community intiative Driven by academic interest rather than needs in climate services Non-uniformity across domains Not all downscaled model outputs are on ESGF (technically challenging to publish these data on ESGF and requires resources)
