ERA-20C is ECMWF's first atmospheric reanalysis of the 20th century, from 1900-2010. It assimilates observations of surface pressure and surface marine winds only. It is an outcome of the ERA-CLIM project
The experiment CLM_20C_ZS contains Northern European regional climate simulations of the years 1960-1989 on a rotated grid (CLM non hydrostatic, 0.44 deg. hor. resolution, see http://www.clm-community.eu
This run (run1, experiment ID a42) 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.
