Summary of plans and status of the v1 low-res water cycle DECK simulation campaign for CMIP6. An overview of the CMIP6 experimental design is available in Eyring at al. (2016, GMD). The "entry card" simulations for CMIP6 consist of the DECK and historical simulations as listed in the table below extract from Table 2 of Eyring et al (2016):
While the minimum ensemble members is one, our goal is between 3 and 5 ensemble members for the historical experiments.

The first DECK simulation is the piControl simulation which requires a minimum of 500 years. Other experiments will all be initialized by branching of from piControl at various stages. A possible scenario is provided in the figure below. Historical_H1, 1pctCO2, and abrupt-4xCO2 would start from year 101 of piControl, amip from year 1870 of historical_H1, historical_H2 from year 151 of piControl and all remaining historical members would be spaced 50 years apart (201, 251, 301).

amip 1850 all forcings
Same as amip but keeping all forcing agents at their 1850 values (to compute time evolving total adjusted forcing).
amip 1850 aerosol forcing
Same as amip but keeping aerosol related forcing agents at their 1850 values (to compute time evolving total aerosol-cloud forcing).
