Use of Light Scattering Phenomena in Atmospheric Aerosol Monitoring
A critical survey of the literature on the use of light scattering mechanisms in the remote monitoring of atmospheric aerosols, their geographical and spatial distribution, and temporal variations. The review was undertaken to aid in the choice of future operational systems, both ground-based and air- or spaceborne. Various techniques and systems are qualitatively and subjectively evaluated. No single system is found to be adequate for operational purposes. A combination of earth surface and spaceborne systems, based mainly on passive techniques involving solar radiation, with active (lidar) systems to provide auxiliary or backup information, is tentatively recommended. Certain deficiencies in the published literature and weaknesses in journal editorial policies, organization of professional meetings and symposia, national science policies, and the support and administration of science and scientists are pointed out.
