Soon after the laser was invented it became obvious that this new inst- ment, providingvisibleandinfraredradiationwithhighintensitydensity and small divergence, would be a great tool for remote monitoring of atmospheric properties by radar-like methods. The lidar method (li for light instead of ra for radio) is thus practically as old as the laser itself. In the beginning, measurements using light scattering of aerosols and dust particles were at the focus of attention, e.g., for investigating v- ibility or cloud heights. As lasers became more intense, and systems for detecting backscattered light more sensitive, Rayleigh scattering was also studied to allow parameters such as variation of the total air pressure or clear air turbulence to be investigated. Furthermore, Raman scattering allowed limited selective detection of gas constituents of the atmosphere. Increasing sophistication of laser systems made it possible tostudytraceconstituentsoftheatmosphere; thiswasthecaseassoonas frequency-tunablelasersystems, eitherline-tunableorcontinuouslyt- able, became available. This made selective absorption and ?uorescence accessible for detecting trace constituents with a sensitivity suf?ciently high to be useful.

Über die Autorin bzw. den Autor

The editor, formerly heading a group of scientists at GKSS Research Center in Geesthacht, Germany, is now a consultant to GKSS. He carried out and supervised many projects in lidar development and applications, both theoretical and experimental. He was awarded Honorary Citizenship of the State of Tennessee and the International Committee on Laser Atmospheric Soundings (ICLAS) Lifetime Award.
