Climate change simulations for 1860-2100 based on IPCC SRES A2 and B2 greenhouse-gas (GHG) scenarios are performed with the coupled climate model ECHO-G. GHG scenarios are considered only without other anthropogenic forcing such as aerosols and ozone. There are two member ensembles for each scenario. We refer to the experiments as "A2Ga", "A2Gb", "B2Ga" and "B2Gb", respectively. Three main GHGs (CO2, NH4, N2O) and 16 minor GHGs including industrial CFCs, HCFCs, and HFCs are utilized for the period of 1860-2100. Observed concentration values are prescribed for the historical period of 1860-1990 while SRES scenario values for the future period from 1990 onward. Initial data for the transient simulations are obtained by spinning up the ECHO-G for five years with the restart file of HOPE-G at the model year 311 ('a' experiments) and 411 ('b' experiments) in the 1000-year control runs (Min et al. 2004, M&D Tech. Report No. 2, http://www.mad.zmaw.de/Pingo/reports/TeReport_Web02.pdf) and climatology of ECHAM4. The enhancement of the three main GHGs concentrations is taken into account in a appropriate way for the whole period of simulations following Roeckner et al. (1999, J. Climate, 3004-3032). Flux corrections are applied only for annual mean heat and moisture fluxes, but no corrections for momentum flux. The model was run on a NEC SX-4 and Sx-5 at the KMA, Seoul, Korea. 300-year control simulations ("CTL") were performed with the same initial condition with "A2Ga" and "B2Ga" but with constant GHG values at 1990 in the same machine SX-4 at the KMA, Korea.
