This run is an IPCC AR4 "pre-industrial control experiment (PIcntrl)" (experiment ID a81) with the coupled climate model ECHO-G. The simulation was started with restart files from the end of year 199 (+ 6 years coupled spi-up) of a preindustrial simulation performed at the Freie Universitaet Berlin (FUB) (same as 20C3m run1). The preindustrial run was initialized with the Levitus climatology. The simulation has been performed using greenhouse gases (GHGs) fixed at 1860 values (CO2 = 286.20 ppm, CH4 = 805.60 ppb, N2O = 276.69 ppb, equi. CFC11 = 12.48 ppb), sulfate aerosol emissions fixed at 1860 values, and solar constant of 1365 W/m^2. This member was run on a NEC SX-6 machine at DKRZ.
