Revised_Simple_Biosphere_Model_(SIB-2)
In climate science, a biosphere model, is used to model the biosphere of Earth, and can be coupled with atmospheric general circulation models (GCMs) for modelling the entire climate system. It has been suggested that terrestrial biosphere models (TBMs) are a more inclusive term than land surface models (LSMs).[1] The representation of roots in TBMs (or LSMs), however, remains relatively crude. Particularly, the dynamic functions of roots and phylogenetic basis of water uptake remain largely absent[2][3] in TBMs (or LSMs).
