Qualidade do Ar - também conhecida como "Modelagem de Dispersão Atmosférica" ( <a href='https://en.wikipedia.org/wiki/Atmospheric_dispersion_modeling'>wikipedia</a> ) é a arte de simular como os poluentes atmosféricos, como PM <sub>2,5</sub> ou Ozônio, se dispersam na atmosfera ambiente.</p> <p>O resultado da simulação fornece a concentração ambiente de cada poluente atmosférico, a partir da qual o Índice de Qualidade do Ar pode ser calculado.</p> <p>Existem dezenas de modelos de dispersão e muitas universidades e instituições em todo o mundo estão a gerir um ou vários deles para diferentes regiões (por exemplo, Europa, EUA Continental, Ásia...). Abaixo está uma lista não exaustiva e selecionada de alguns modelos que estão sendo usados para fornecer previsões de qualidade do ar no projeto "Índice Mundial de Qualidade do Ar".</p> <style
