The BIOMASS Methodology provides a formal procedure for the development of assessment
biospheres in general. It was developed through the creation of the BIOMASS Example
Reference Biospheres. The BIOMASS Methodology is based on a staged approach in which
each stage introduces further detail so that a coherent biosphere system description and
corresponding conceptual, mathematical and numerical models can be constructed. The
Methodology is summarised in Figure 1.
