Conclusion
Atmospheric and Meteorological Lidars Basic principles

This article presented the direct lidar operation to obtain the useful optical signal. The principles, instrumentation and spectroscopies involved in lidar measurements were described, with a presentation of the concepts and equations used in the article [E 4 311] to describe the various lidar methods depending on the light-matter interaction processes involved: elastic or Raman scattering, differential absorption, Doppler effect. Numerical applications show the respective roles of instrumental and atmospheric quantities in the link budget and signal-to-noise...
