model output discussed in Dietze et al. (2014) ref refers to the reference run dubbed MOMBA 1.0 vel_micom_iso_???? refer to integrations branched off the reference in 1993 and continued with differing horizontal laplacian viscosities (shown in Fig. 15 (a)). E.g., 5em4 refers to vel_micom_iso=5e-4 visc_cbu_iw_???? refers to integrations branched off the reference in 1993 and continued with differing vertical viscosities (shown in Fig. 15 (b)). E.g., 1em4 refers to visc_cbu_iw=1e-4 repeat? refer to integrations repeated from the 1.1.1993 restart with no changes whatsoever (shown in Fig. 21).
