Design for the mid-Holocene run
PMIP4-CMIP6 name of the experiment: midHolocene
Associated publication: Otto-Bliesner et al, in prep
| PMIP4-CMIP6 specifications | |
|---|---|
| Astronomical parameters | eccentricity = 0.018682 obliquity = 24.105° perihelion-180° = 0.87° Date of vernal equinox : March 21 at noon |
| Trace gases | CO2 = 264.36 ppm CH4 = 584.93 ppb N2O = 258.56 ppb CFC = 0 O3 = same as in CMIP6 piControl |
| Solar activity | Same as in CMIP6 piControl |
| Ice sheets | Same as in CMIP6 piControl |
| 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 cf. documenting papers: Otto-Bliesner et al, in prep and Kageyama et al, subm. Access to data |
| Vegetation | Depending on model complexity: 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: Otto-Bliesner et al, in prep and Kageyama et al, subm. |
