The BMRC model is a descendant of a spectral general circulation model first developed in the 1970s (cf. Bourke et al. 1977 , and McAvaney et al. 1978 ). This version is more recent than that used for the first BMRC AMIP experiment (Version 2.7)
For the PMIP, BMRC consists of runs 6 and 0. For the PMIP, BMRC2 consists of runs 21 and 0.
