ScenarioMIP Experimental Protocols
The experimental design of the Scenario Model Intercomparison Project (ScenarioMIP) consists of eight 21st century scenarios and three long term extensions grouped into two tiers by priority, see overview in table below.
The first tier contains four scenarios, while the second tier contains four additional 21st century scenarios, including an overshoot scenario whose peak in radiative forcing occurs in the 21st century; additional ensemble members for one of the 21st century scenarios from Tier 1, and three long-term extensions that begin from the end points of some of the 21st century scenarios and extend to 2300. See the ScenarioMIP paper for further discussion of the design, link below.
