2001-2100

Jan 1978 from AMIP (run 1) including precalculated Q-flux from AMIP (run 1). Well mixed greenhouse gases (CO:sub:2, CH4, N2O, F11, F12) are constant (year 1985). Present-day ozone climatology (Fortuin and Kelder, 1998) and background aerosol (Tanre et al., 1984) is applied.

6H

MM

1978-1999

Jan. 1978 (observed) for all 3 runs. Initial perturbations in runs 2, 3 are realized by small changes in the horizontal diffusion coefficients during the first month. Well mixed greenhouse gases (CO:sub:2, CH4, N2O, F11, F12) are constant (year 1985). Present-day ozone climatology (Fortuin and Kelder, 1998) and background aerosol (Tanre et al., 1984) is applied.

Comments

  • ‘Name’ denotes the experiment name in the CERA database

  • ‘period’ is the time in calendar years for experiments 20C, A1B, B1 und A2. In the experiments CTL, 1CO2 und CMIP4 there is no reference to the calendar. In experiment 1CO2, for example, model year 1930 denotes year 70 (the time of CO2 doubling) after the start of the experiment.
