EH4_T30_HOPE_EEM Eemian Control Run (125 kyBP) 12H values

Kaspar, Frank

Experiment
Summary
Simulation of the climate of the Eemian interglacial at 125000 years before present.
Boundary conditions are the same as in the control run (EH4_HOPE_T30-CTL), apart from the concentration of anthropogenic greenhouse gases and orbital parameters:
Greenhouse gas concentrations are derived from vostok ice core data:
270 ppmV CO2 (instead of 353), 0.63 ppmV CH4 (instead of 1.72) and 260 ppbV N2O (instead of 310).
Orbital parameters have been calculated with the routine of Berger (1978):
Eccentricity: 0.04; Obliquity: 23.79; Precession: 127.3

ECHO-G is used as climate model. It is a coupled atmosphere/ocean model (ECHAM4_T30 + HOPE-E_T42er). The simulation was run on a NEC-SX6 (hurrikan).
Atmospheric data is stored every 12 hours. Monthly means are available, too.
Ocean data is stored every month.

- EH4_HOPE_T30-CTL control run (1000 years of simulation) (run c04)
- EH4_HOPE_T30-PRI preindustrial control run (ca. 1800 A.D.; run a20)

The simulation was performed in the context of the DEKLIM-EEM project.
