| Abstract: | We have applied two spectroscopic techniques in order to investigate air pollution dispersion in real and simulated atmosphere: the Titan–Sapphire laser technique based on differential absorption lidar (DIAL), and CO2 laser photoacoustic spectrometry (LPS). A set of spatial NO2 measurements was performed over a highway outside a city and in an urban street canyon with extensive traffic. Qualitative agreement was found between the results obtained by DIAL and by physical modeling based on LPS measurements in a wind tunnel. |
