Uncertainty and sensitivity
Obviously, numerous sources of uncertainty in the various components of IMAGE 2.4 influence its analytical results, ranging from data imprecision and model uncertainties, to scenario assumptions in applications. To date, no comprehensive and systematic exploration has been performed of key uncertainties and how they are propagated throughout the entire IMAGE model to influence the final results. Currently, plans are being developed to undertake this demanding exploratory task. What has been done in many instances is to look at uncertainties in underlying data and model formulations in sub-systems of the overall framework, thus providing partial sensitivity analyses for IMAGE 2.4 framework.
