Neste estudo procedeu-se à recolha de dados de temperatura, humidade relativa e matéria particulada, em 10 campanhas itinerantes. Para avaliar a sua concentração, as partículas foram magnetizadas e medidas a 1T (tesla), -25 mT, -100 mT e -300 mT,. O conhecimento das áreas com situações frequentes de estabilidade absoluta, associadas a inversões de gradiente térmico intensas, é importante, pois a diminuição da camada de mistura, provocará uma dispersão ineficiente dos poluentes, onde a matéria particulada, não é excepção.
In this study, temperature, relative humidity and particulate matter data were collected in 10 itinerant campaigns. The particles were magnetized and measured at 1 T (tesla), -25 mT, -100 mT e -300 mT, in order to assess its concentration. The knowledge of frequent absolute stability area, associated with intense thermal inversions, is important, because the decrease of the mixture layer will cause inefficient dispersion of the pollutants and particulate matter is not an exception.
