TL;DR: In this article, a combined lidar-photometer method that permits the retrieval of vertical profiles of ash and non-ash (fine-mode) particle mass concentrations is presented.

TL;DR: In this paper, the authors present results from a four-month campaign which took place in summer 2009 in Cabauw, The Netherlands, where they measured the aerosol scattering coefficient σsp(λ) was measured dry and at various, predefined RH conditions between 20 and 95% with a humidified nephelometer.

TL;DR: In this article, the authors show the four-dimensional (4-D) distribution of the Eyjafjallajokull volcanic cloud in the troposphere over Europe as observed by EARLINET during the entire volcanic event (15 April-26 May 2010).

TL;DR: The CINDI campaign for Nitrogen Dioxide measuring instruments (CINDI) as discussed by the authors evaluated the accuracy of state-of-the-art ground-based measurement techniques for the detection of atmospheric nitrogen dioxide (both in-situ and remote sensing).

TL;DR: In this paper, the European Aerosol Research Lidar Network (EARLINET) quality-assurance efforts at instrument level have been discussed at signal and product level.
