8.6 Conclusions

The application of differential absorption lidar to narrow lines of the rotational-vibrational spectrum of water vapor or oxygen for humidity and temperature profiling is technically demanding with respect to the laser source and the data acquisition. Many details need to be considered carefully in system design and data evaluation. If that is done properly the technique is very powerful, in particular for water-vapor profiling. The main strengths of DIAL in ground-based applications are its excellent daytime performance for high-resolution studies in the boundary layer and high-accuracy routine observations in the lower half of the troposphere, as well as its independence from external calibrations. Suitability for airborne and probably also for spaceborne applications is definitely another very important feature of the method.
