| Volcanic activity | Same as in CMIP6 piControl |
| Aerosols | Modified sources, atmospheric concentrations or radiative forcing, depending on model complexity and model configuration used for DECK and historical experiments cf. documenting papers: Otto-Bliesner et al, in prep and Kageyama et al, subm. Access to data |
| Vegetation | Depending on model complexity and model configuration used for DECK and historical experiments: Interactive vegetation or Interactive carbon cycle (LAI) or Prescribed to present-day values or lig127k values computed from off-line vegetation model The methodology to represent vegetation should be the same as for the CMIP6 piControl simulation cf. documenting papers: Otto-Bliesner et al, in prep and Kageyama et al, subm. |
