General Information

Name
ECHOG_A15_PRI: 2000 year control run of preindustrial climate (DEKLIM-EEM project), monthly mean values
Acronym
ECHOG_A15_PRI_MM
Project
DEKLIM-EEM (Climate change at the end of a warm stage)
Summary
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 preindustrial climate (PRI) at around 1800 yr AD. Boundary conditions are equivalent to the other simulations of the project, apart from the concentration of greenhouse gases and orbital parameters:
Greenhouse gas concentrations are derived from vostok ice core data: 280 ppmV CO2, 0.70 ppmV CH4 and 265 ppbV N2O. CFCs are set to zero.
Orbital parameters have been calculated with the routine of Berger (1978):
Eccentricity: 0.0167; Obliquity: 23.44; Perihelion: 282.7
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.
