Atmospheric dispersion models are an essential tool for assessment of emergency situations related to airborne particles or gases released into the atmosphere by natural or man-made hazards. They are used complementary to observational data in order to fill-in e.g. temporal- or spatial gaps and to conduct forecasts facilitating the planning of mitigation strategies.
The focus of this session will be on environmental emergency scenarios (airborne hazards) which can have extremely high impact on society and environment: volcano eruptions, nuclear accidents, as well as more localised emergencies, such as dust storms and strong vegetation fires or other occasions when hazardous pollutants are injected into the atmosphere.
