| PMIP4-CMIP6 specifications | |
|---|---|
| PMIP4-CMIP6 name | lgm |
| Astronomical parameters | eccentricity = 0.018994 obliquity = 22.949° perihelion-180° = 114.42° 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. |
