Real-time dispersion model calculations as part of NORMEM-WP19

Abstract The Chernobyl accident made it clear for all: Norway was badly prepared for an accident of this kind. Institutions and scientists who had relevant information, data and expertise on the subject, felt frustrated because there was no suited system where their contributions could be delivered, assessed and synthesized. An information crisis developed. Norway is better prepared to handle such a situation today. New tools are being developed. An improved administrative structure has been created which is more suitable for handling the flow of information and serves as a rational basis in the decision-making process. With the implementation of the Norwegian Application of MEMbrain, NORMEM, the situation is expected to improve significantly. The Norwegian Meteorological Institute (DNMI) has a central role to play and important contributions to give in this new administrative structure. In this paper we will describe DNMIs role in the decision-making process and show examples of use of the tools developed specially adopted to this role.
