T. Tirabassi et al., CARBON-MONOXIDE CONCENTRATIONS EVALUATED BY TRAFFIC NOISE DATA IN URBAN AREAS, Nuovo cimento della Societa italiana di fisica. C, Geophysics and space physics, 21(2), 1998, pp. 149-159
It is shown that variations in carbon monoxide concentrations can be e
valuated bg measuring environmental noise, wind velocity and vertical
thermal stability. The results can be justified on the basis of the th
eory of the street canyon effect. The methodology proposed was Verifie
d in two Italian cities with different characteristics: Milan and Rave
nna.
