ECHOG_A40_LGI: Control Run for the Last Glacial Inception (End of the Eemian, 115 kyrBP, DEKLIM-EEM project), monthly mean values

The purpose of the project DEKLIM-EEM is to reconstruct past interglacials based on proxy data and to understand the processes that are responsible for climatic changes during these interglacials by applying climate models.

The data represent monthly average value of a simulation of the Last Glacial Inception (LGI) at 115000 years before present(End of the Eemian). Boundary conditions are the same as in the preindustrial control run (ECHOG_A15_PRI), apart from the concentration of greenhouse gases and orbital parameters:

Greenhouse gas concentrations are derived from vostok ice core data: 265

ppmV CO2, 0.52 ppmV CH4 and 270 ppbV N2O.

Orbital parameters have been calculated with the routine of Berger (1978):

Eccentricity: 0.0414; Obliquity: 22.41; Perihelion: 290.9

The simulation has been started with the Levitus ocean climatology.

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 were originally stored by the model every 12 hours. Ocean data is stored every month. As the boundary conditions are not time dependent, the time access is arbitrary.

Related experiments:

ECHOG_A15_PRI preindustrial control run (ca. 1800 A.D.; run a15), started with Levitus climatology.

ECHOG_A16_LIG control run, last interglacial (Eemian, 125 kyrBP; run a16), started with Levitus climatology.
