 | | The multi-nation, high-resolution field study of Meteorology And Diffusion Over Non-uniform Areas (MADONA) was conducted by scientists from the United States, United Kingdom, Germany, Denmark, Sweden, and The Netherlands at Porton Down, Salisbury, Wiltshire, UK during September and October 1992. |
 | | MADONA was designed and conducted for high resolution meteorological data collection and diffusion experiments using smoke, sulphurhexaflouride (SF), and propylene gas during unstable, neutral, and stable atmospheric conditions in an effort to obtain terrain-influenced meteorological fields, dispersion, and concentration fluctuation measurements using specialized sensors and tracer generators. |
 | | Simulations of airflow and diffusion over the MADONA topography (a 9 km by 7.5 km area) were made with a variety of models. |
