Topography and coastlines Same as in CMIP6 piControl
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
