Experiments, runs, publication

Note : experiment names below are CMIP5 ones; please refer to the CMIP5 design document for details

piControl

The 850-year run is published

Note on ensembles

Ensembles are formed by choosing initial states at various years in piControl simulation, separated by at least 50 years (see details further below ). CMIP5 rules are strictly respected regarding members numbering consistency between different experiments (e.g RCP85 #2 starts from historical #2, and historical #4 starts with same initial state as historicalGHG #4)).

Recent past family

• historical and historicalExt ensembles have 10 members (# 1 to 10)
• historicalNat ensemble has 6 members (# 1,2,3,4,5,8).
• historicalGHG ensemble has 6 members (# 1,2,3,4,5,8).
• historicalMisc ensemble has 10 members (# 1 to 10) ; they were run using all anthropogenic forcings.

RCP

• RCP8.5 is an ensemble of 5 members (#1, 2, 4, 6 and 10). Member 1 has an extension to 2300, is recommended for Cordex BC, and includes 6hLev data for 21st century.
• RCP4.5 includes a single member, and was run up to 2300. It includes 6hLev data for the 21st century.
• RCP2.6 includes a single member.
• extension of RCPs for RCP8.5 and RCP4.5 from 2100 to 2300 were run.

Paleo climate

• midHolocene : this run starts at the fake year 1950
• lgm : the run is in the spin-up phase; it is the only one not published

CFMIP :

• amip, amip4xC02, amip4K, amipFuture
• aquaControl, aqua4K and aqua4xCO2

Ensembles

1. All runs start on january, 1st.
2. Within each ensemble, members branch time are separated by at least 50 years.
3. Branch year varies monotonically with member number, except for members 1 and 8, as indicated below : member 1 branches from year 400, and member 8 from year 0 (i.e 1850-01-01).
4. For RCP runs, the branch year should be understood as "branch year in piControl of the historical run, from which this RCP run does branch (in year 2006)"
