aerosol

The University of Milan and the National Research Council have analyzed for the first time the horizontal visibility of the atmosphere, discovering that, in the most polluted areas of the country, the frequency of days with visibility above 10 or 20 km is more than doubled in the last 40 years, thanks to the regulations implemented to reduce pollution. The publication is available on “Atmospheric Environment(https://doi.org/10.1016/j.atmosenv.2019.116861).
