Coordinated Time-slice Experiments

Leader: Rowan Sutton (University of Reading)

Objective: Controlled experiments repeated with several different climate models to advance understanding of the factors/processes controlling future climate and related uncertainty in climate forecasts.

A series of coordinated time-slice experiments are planned within RT4 as a cross-cutting activity linking all the Work Packages. The experiments will be designed to investigate and understand factors controlling climate at selected time periods (e.g. 1850, 2000, 2050). The experiments will be conducted with both atmospheric and coupled GCMs. Specific experiments will be designed to investigate issues such as the role of specific feedbacks, sensitivity to resolution, and sensitivity to oceanic initial conditions.
