DECKDiagnostic, Evaluation and Characterization of Klima

Every participating model in CMIP7 will run a common set of experiments at minimum. CMIP7 adds the historical and esm-hist runs and three fixed-SST piClim experiments to the CMIP6 set.

Climate REF

CMIP7 evaluations are now available

The Rapid Evaluation Framework (REF) runs a common set of diagnostics for CMIP7 output as they become available, so models can be compared against observations and each other. This is updated daily.

Climate Resource helps maintain the REF, working with the diagnostic providers PCMDI, ESMValTool and ILAMB.
