RISØ National Laboratory, Denmark -Wind Energy Department/Meteorology

The Wind Energy in the Department of Wind Energy at Risø NL is an internationally renowned centre of excellence for atmospheric boundary layer research. As of January 1. 2007, Risø has merged as a national Laboratory with the Technical University of Denmark Through R&D work, the Meteorology Program embedded within the Wind Energy Department engage in atmospheric dispersion related knowledge and methodologies including computer models used by industry, institutes, and governmental authorities. In close collaboration with Risø’s Radiation Research Department the meteorology program works in the fields of radiation safety, radiation physics, radioecology, tracer studies, radiochemistry, isotopes, nuclear instruments, and industrial and medical applications of nuclear methods.

The Meteorology Programme holds meteorological expertise related to atmospheric dispersion of radionuclides from nuclear emergencies. This goes back to the time Risø was a Nuclear Energy research establishment (since 1951). The Risø meteorology programme involves field measurements, modelling activities and theoretical developments. Risø NL has been active in this field since the late sixties. Risø has in addition a national responsibility for consolidating the knowledge base on nuclear issues and providing consultancy to governmental authorities. See

Torben Mikkelsen, Senior Scientist, Ph.D.
is the leader of a group working with atmospheric turbulence and dispersion, including remote sensing. TM has long-time experience with project co-ordination both in Denmark and in the previous EU framework programmes FP3, FP4 and FP5. His field of research includes instrument developing (High-resolution Aerosol- backscatter Smoke-Lidar (1988 -), Thermocouple fast-responding sensors (1994-) Inversion height determination Lidar (1997) and methodologies, concepts and models for emergency response modelling: (Wind and turbulence models LINCOM-hill, roughness change, thermal stratification. Dispersion modelling is centred about the Urban/Local/Meso-scale puff model RIMPUFF. TM has designed the nested model chains for the now operational Emergency response and Preparedness Systems MET-RODOS and ARGOS_NT Nuclear emergency response decision support systems. During FP5 TM has acted as co-ordinator for the FP5 ENSEMBLE project Methods to Reconcile Disparate National Long Range Dispersion Forecasts; Contract FIKR-CT-2000-00038. During FP6 TM and his Risø team participates in the Radiation Protection EURANOS IP regarding several atmospheric dispersion related issues, including Data Assimilation.

Poul Astrup, Senior Scientist, Ph.D.:
Is a senior research engineer at Risø with more than 10 years experience working with the ARGOS and RODOS and he has had a central role in the development and implementation of the LSMC-RIMPUFF local scale model chain in these Decision Support Systems. PA has been a main developer of the data assimilation model RIMPUFF_DA in RODOS. PA is presently developing an urban dispersion model called URD for integration with ARGOS. PA is continuing participating in the ENSEMBLE long-range models intercomparison tests with the RODOS integrated code systems MATCH (Swedish long range dispersion model) and the combined LSMC-RIMPUFF/MATCH.
