This five box ocean-atmosphere model is originally based on the model presented by Slomp and Van Cappellen (2007; Biogeosciences), which was later edited to consider additional aspects of the Earth system by Tsandev et al. (2008; GBC) Tsandev and Slomp (2009; EPSL) and then tranlsated to consider geological timescales by Alcott et al. (2019; Science).
