Model output used for the paper "Climate Implications of the Sun transition to higher activity mode"

We used SOCOL3-MPIOM model with an interactive ocean (Stenke et al., 2013; Muthers et al., 2014), which allows the evaluation of possible implications of the Sun activity switch for the terrestrial climate and ozone layer. It is based on the general circulation model ECHAM5.4 (Roeckner et al., 2003) interacting with the chemistry module MEZON (Egorova et al., 2003; Rozanov et al., 1999) and the MPIOM (Jungclaus et al., 2006; Marsland et al., 2003) for the treatment of the ocean dynamics. We executed our two 90-year-long experiments using T31 truncation providing 3.75x3.75 horizontal resolution and 39 levels in vertical direction covering the atmosphere from the ground to the mesopause at 0.01 hPa (~ 80 km altitude). Both experiments were initialized from a very long time slice spin-up run performed using preindustrial set-ups for all forcings. In the reference run, we prescribed monthly SSI for the year 2000 (solar activity maximum). In the second (experiment) run, we applied monthly SSI for the Sun in transition to a very active state.
