Carbon modelling has been pioneered by Ulrich Siegenthaler and Hans Oeschger at CEP in the
1970ies. Projections of atmospheric CO2 with the “Bern model” were instrumental in the first
Assessments by the Intergovernmental Panel on Climate Change and for the legally-binding metric to
compare emissions of different greenhouse gases in the Kyoto Protocol.
Since the development of the early reduced-form, box-diffusion model, the numerical model
hierarchy and the range of applications has been continuously expanded.
The following models are
currently used by the group and developed and applied in collaboration with the groups at CEP and
in national and international collaborations.
