Description | |
Summary | The 1984 Oresund Experiment was an international project with the purpose of investigating the nature of turbulence and atmospheric dispersion over a land-water-land area. The main objective was to obtain a comprehensive data set suitable for verifying mesoscale meteorological and dispersion models in a coastal environment. The experiment was carried out over the 20-km-wide strait of Oresund between Denmark and Sweden. The meteorological observational network extended over an 80-km-wide cross-section through Oresund and a large proportion of the available micro- and meso-meteorological instrumentation in the Nordic countries was employed. In addition, considerable contributions were made by non-Nordic countries. The dispersion process was investigated by SF6 tracer experiments and by tetroon flights. The tracer measurements comprised time-averaged concentrations at several fixed positions in an arc-like set-up, and instantaneous concentrations from a van, a boat and an aircraft. Emphasis was put on conditions when the water was colder than the surrounding land-areas, which in the experimental period typically occurred during daytime. The experiment took place in the period May 15 to June 14, 1984. A special intensive measuring program was carried out from June 4-10. The experiment was a joint effort of 15 institutions situated in the Nordic countries (Denmark, Finland, Norway and Sweden) as well as in Belgium, the Federal Republic of Germany and the Netherlands. |
