Coupled Model Intercomparison Project (CMIP3)

Coupled Model Intercomparison Project (CMIP3) is a set of climate model experiments from 17 groups from 12 countries with 24 models.

In detail

The resulting dataset from the CMIP3 project is the largest and most comprehensive international global coupled climate model experiment ever attempted (Meehl et al. 2007).

CMIP3 data is used within the marine projections where it is used to estimate the time-mean sea-level rise. This is because the Met Office Hadley Centre PPE is based around one model structure in which only atmospheric parameters are perturbed.

  • An overview of how CMIP3 data was used in UKCP09 is provided in of the UKCP09 Marine & coastal projections report. describes in more detail the approach adopted in UKCP09 to provide future sea level projections.
