class='bigletter'>Luchtkwaliteitsvoorspelling - ook wel "Atmospheric Dispersion Modeling" ( <a href='https://en.wikipedia.org/wiki/Atmospheric_dispersion_modeling'>wikipedia</a> ) genoemd, is de kunst van het simuleren van hoe luchtverontreinigende stoffen, zoals PM <sub>2,5</sub> of ozon, zich in de omgevingsatmosfeer verspreiden.</p> <p>Het resultaat van de simulatie geeft de omgevingsconcentratie voor elke luchtverontreinigende stof, waaruit de luchtkwaliteitsindex kan worden berekend.</p> <p>Er zijn tientallen spreidingsmodellen en veel universiteiten en instellingen over de hele wereld gebruiken er één of meerdere voor verschillende regio's (bijvoorbeeld Europa, het vasteland van de VS, Azië ...). Hieronder vindt u een niet-uitputtende en geselecteerde lijst van enkele modellen die worden gebruikt voor het leveren van luchtkwaliteitsvoorspellingen in het kader van het "World Air Quality
