Abstract

During the past three decades laser radars (lidars) become an important tool for the range-resolved remote-sensing of atmospheric constituents. Amongst these are aerosols, that represent a strong, poorly-known modulator of the Earth’s climate. In this chapter the reader will first find an introduction to the lidar technique in terms of instrumental components. The lidar equation, describing the factors controlling the atmosphere- backscattered signal will then be addressed. Solution of the lidar equation to retrieve optical properties of atmospheric aerosol will be considered. Finally, a method to retrieve aerosol extinction, surface area and volume from single-wavelength lidar observations will be discussed. These arguments should suffice to deal with both the managing of simple lidar systems and with the comprehension of the large amount of information that forthcoming, space-based lidars will provide in the near future.
