PMIP4-CMIP6 name | lgm |
Astronomical parameters | eccentricity = obliquity = ° perihelion-180° = ° Date of vernal equinox : March 21 at noon |
Trace gases | CO2 = 190 ppm CH4 = 375 ppb N2O = 200 ppb CFC = 0 O3 = same as in CMIP6 piControl |
Solar activity | Same as in CMIP6 piControl |
Ice sheets | Modified Access to data |
Topography and coastlines | Modified Access to data |
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: Kageyama 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 mid-Holocene 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: Kageyama et al, in prep and Kageyama et al, subm. |
