TL;DR: The results show the necessity of making additional independent measurements, which can provide a suitable approximation of the lidar ratio, and prove in general, that the data evaluation schemes of the different groups of lidar systems work well.

TL;DR: In this article, a multi-year climatological study of Saharan dust intrusions in the central Mediterranean in terms of aerosol optical parameters vertical profiles is carried out for the first time.

TL;DR: In this paper, a statistical analysis concerning the vertical distribution of the volume light extinction coefficients of particles derived from Raman lidar measurements at 10 EARLINET stations is presented, where the profiles were measured on a fixed schedule with up to two measurements per week; they typically covered the height range from 500 m to 6000 m above ground level (agl).

TL;DR: In this article, the authors provide an overview of recent advances in instrumentation and methodologies for measuring atmospheric composition changes from space, aircraft and the surface as well as recent improvements in laboratory techniques that permitted scientific advance in the field of atmospheric chemistry.

TL;DR: In this paper, different retrieval methods to derive the aerosol backscatter coefficient βp, with special focus on the calibration of the ceilometers, are compared with respect to their accuracy and applicability, and it is shown that advanced lidar systems such as those being operated in the framework of the European Aerosol Research Lidar Network (EARLINET) are excellent tools for the calibration.
