See summary of corresponding experiment. This dataset contains Monthly Means. Records are in temporal order [from model date 01.01.0174 to 30.12.699]. Years in the GRIB-header are being counted from 74-99, 0-55, 0-99 ... Model years 174 to 208 correspond to the spin down period. Model years 209 to 699 were simulated using the changes in solar constant, CO2 and CH4 concentrations estimated for the period 1500 to 1990 A.D.
