Sensing Systems For Environmental Measurements: Influence of Wind on Particulate Matters and Ozone

Particulate matters and ozone are often neglected as pollutant elements when people deal with widespread pollution. Particulate matters PM 10 , PM 2.5 , are produced by human activities namely industries and car traffic but also by natural activities like blowing wind from desert, volcanoes, etc... Ozone, instead, has a double consideration: it is beneficial as ozone layer in the upper atmosphere because it serves as natural filter to reduce UV rays that arrive at earth surface. But at ground level, high amounts of ozone, in terms of concentration are harmful for human health. The research presents the effect of wind in a transitional and seasonal period on particulate matters and ozone. The paper also illustrates the application of retarded differential functional equations or delayed differential functional equations for studying the effect of wind in pollution distribution.
