Concentrations of major UVabsorbing species are evaluated at the tailpipe of in-use vehicles (NO, NO2, EC) and in urban atmosphere over a 200m-long optical path (O2, O3. NO2, EC, nitrates). Also, we report on the detection in both environments of an additional compound, the nanometric organic carbon (NOC), known to form in fuel-rich flames, which is not considered yet in ordinary emissions inventories. Also, the problem of dilution/dispersion of primary species is addressed, by tracking the combustion-formed CO2 at the tailpipe and in urban atmosphere."^^xsd:string ; pubblicazioni:affiliazioni "1) Istituto Motori, CNR, Napoli; 2) ARPA Lombardia, Brescia, Italy."^^xsd:string ; pubblicazioni:titolo "Optical soundings of cars\u0092 exhaust and urban atmosphere with laser-plasma light and open-path spectrophotometry"^^xsd:string ; prodottidellaricerca:abstract "Optical soundings of cars\u0092 exhaust and urban atmosphere with laser-plasma light and open-path spectrophotometry based on a Laser-Produced Plasma as the light source.
