ROLE OF COMBINED OPTICAL TECHNIQUES FOR THE REMOTE SENSING OF ATMOSPHERIC ENVIRONMENT
Optical techniques in the study of atmospheric pollution are now well proven, spanning from Lidar and differential Lidar, to correlation spectrometry, to laser fluorometry. Typical areas of interest are areal pollution, local transport and chemical evolution of pollutant species. We discuss here some methodological aspects necessary for optical remote sensing to be fully operational in environmental control: 1) Synergetic operation. Classical Lidars, differential Lidars and correlation spectrometers, combined, render the mapping of aerosol and gaseous components over a densely polluted area a realistic goal. Moreover, they are the basis for evalution of problems of acid deposition, pollution transport, massbalance and fall out. At present, main requirements for practical progress are: a) some increase in sensitivity and selectivity of individual techniques; b) and full blending of mobility, real time operation and interactive control for the various techniques. Some developments are discussed, with special regard to classical Lidar and Cospec systems. 2) Auxiliary competences for better exploitation of each technique. E.g: insertion of multispectral detection features into a tunable Lidar system; polarization analysis and 2-wavelength operation added to any Lidar technique (probing of tropospheric structures, inversion and convective layering, visibility, and condensation phenomena).
