ECHOG_A46_20C3M_RUN5: 5th member of 20C3M simulations for IPCC AR4

Lee, Hyo-Shin

Experiment
Summary
This run (run5, experiment ID a46) is one member of a five-member ensemble simulation (run1 to run5) of the IPCC AR4 "climate of the 20th Century experiment (20C3M)" with the coupled climate model ECHO-G. Initial data for the 20C3M simulations (ID = a42-a46; period = 1860-2000) were obtained by spinning up ECHO-G for six years with ocean restart files from simulation years=199/299/399 of a preindustrial simulation performed at the Freie Universitaet Berlin (FUB) and from simulation years=199/299 of the first ensemble member respectively. The preindustrial runs were initialized with the Levitus climatology. Anthropogenic GHGs (ENSEMBLE project), sulfate aerosol direct and first indirect effects, and natural forcing (solar irradiance and volcanic activity implemented through varying solar constant following Crowley, 2000) are used for the 20C3M simulations. This member was run on a NEC SX-6 at KISTI.

Description
The 4th and 5th realisations of the IPCC AR4 20C3M experiment (ECHOG_A45_20C3M_RUN4 and ECHOG_A46_20C3M_RUN5) were started from a restart file of an integration with 12 hourly diagnostic output intervals. The experiments were run with 3 hourly diagnostic output intervals which caused an inconsistency of the data values of the first output interval. The consistency has some impact on the monthly mean values through averaging. The first time level of any of the variables in the two experiments should therefore not be used.
