Modelling of air pollution
Dispersion models and atmospheric process models are useful tools for determining how emissions, meteorological conditions and chemical processes affect air pollution levels and throughfall of different substances. IVL has an extensive operation in the field of dispersion calculation and modelling of atmospheric chemical processes.
The modelling tools we use are flexible, and allow us to model meteorology with high resolution, dispersion of flue gas plumes, detailed atmospheric chemistry and secondary aerosolization, as well as dry and wet deposition. We work with several different models, from advanced three dimensional dispersion models to empirical models.
Dispersion models make it possible to simulate emission scenarios, and dispersion calculations are also very useful in studies of how ventilation and pollution levels are affected by urban density. We also model smells, dust, exposure and allergenes. The results are often used when assessing permit applications.
