From Operational Systems
City dwellers and urban planners are pressing for more and more information on air quality. NUMTECH has developed an operational system that analyses previous days' events, real-time situations and provides 3-day forecasts on changes in air quality. These monitoring systems use several different atmospheric dispersion models (Lagrangian, Eulerian, Gaussian) to produce extremely fine-scale spatio-temporal forecasts. The information can be made available to a group of urban areas, a town, a business district, a throughway, a neighbourhood or a street.
- Local authorities
- Public bodies
The Urban’Air system enables institutional networks, the Associations Agréées de Surveillance de la Qualité de l’Air (ASQAA - French Air Quality Monitoring Network) in particular, to provide a day-to-day air quality monitoring and forecasting service at street-scale for a whole city or town. The dispersion models used factor in all possible emission sources: transport networks - roads in particular - industrial sites, residential and commercial emissions, ports, airports, natural sources.
