“…EARLINET data have been used for a first statistical range-resolved analysis of aerosol optical properties over Europe (Matthias et al, 2004b), climatological studies (Amiridis et al, 2005;De Tomasi et al, 2006;Mattis et al, 2004Mattis et al, , 2008Wandinger et al, 2004;Navas-Guzmán et al, 2013a;Preißler et al, 2013), longrange transport analysis Damoah et al, 2004;Wang et al, 2008;Sawamura et al, 2012;Pappalardo et al, 2013;Mattis et al, 2010), aerosol characterization, and implication of dust in weather forecast modeling (Pérez et al, 2006a). Moreover, retrieval algorithms for aerosol microphysical properties were developed and tested extensively with synthetic data and with real multiwavelength lidar data (e.g., Veselovskii et al, 2002, 2005Böckmann et al, 2005;Balis et al, 2010;Alados-Arboledas et al, 2011;Gasteiger et al, 2011;Mamouri et al, 2012;Wagner et al, 2013;Navas-Guzmán et al, 2013b).…”

“…Beside climatological measurements, EARLINET also performs specific observations during special events such as Saharan dust outbreaks (e.g., Ansmann et al, 2003;Balis et al, 2004;Mona et al, 2006;Guerrero-Rascado et al, 2009;Wiegner et al, 2011), volcanic eruptions (e.g., Pappalardo et al, 2004bPappalardo et al, , 2013Wang et al, 2008;Ansmann et al, 2010;Groß et al, 2011a;Navas-Guzmán et al, 2013b), and biomass burning (e.g., Alados-Arboledas et al, 2011, Amiridis et al, 2009, Müller et al, 2007bMattis et al, 2003). In particular, within the network, an alert service for Saharan dust outbreaks has been established based on the use of operational dust forecasting of different regional models, such as the Skiron ) and BSCDREAM8b (Barcelona Supercomputing Center -Dust Regional Atmospheric Model) models (Pérez et al, 2006b, c;Basart et al, 2012).…”

Abstract. The European Aerosol Research Lidar Network, EARLINET, was founded in 2000 as a research project for establishing a quantitative, comprehensive, and statistically significant database for the horizontal, vertical, and temporal distribution of aerosols on a continental scale. Since then EARLINET has continued to provide the most extensive collection of ground-based data for the aerosol vertical distribution over Europe. This paper gives an overview of the network's main developments since 2000 and introduces the dedicated EAR-LINET special issue, which reports on the present innovative and comprehensive technical solutions and scientific results related to the use of advanced lidar remote sensing techniques for the study of aerosol properties as developed within the network in the last 13 years.Since 2000, EARLINET has developed greatly in terms of number of stations and spatial distribution: from 17 stations in 10 countries in 2000 to 27 stations in 16 countries in 2013. EARLINET has developed greatly also in terms of technological advances with the spread of advanced multiwavelength Raman lidar stations in Europe. The developments for the quality assurance strategy, the optimization of instruments and data processing, and the dissemination of data have contributed to a significant improvement of the network towards a more sustainable observing system, with an increase in the observing capability and a reduction of operational costs.Consequently, EARLINET data have already been extensively used for many climatological studies, long-range transport events, Saharan dust outbreaks, plumes from volcanic eruptions, and for model evaluation and satellite data validation and integration.Future plans are aimed at continuous measurements and near-real-time data delivery in close cooperation with other ground-based networks, such as in the ACTRIS (Aerosols, Clouds, and Trace gases Research InfraStructure Network) www.actris.net, and with the modeling and satellite community, linking the research community with the operational world, with the aim of establishing of the atmospheric part of the European component of the integrated global observing system.

“…Our lidar BILLI (BrIdge voLcanic LIdar) [22], for example, has recently been used to successfully retrieve three-dimensional tomographies of volcanic CO 2 in the plumes of Pozzuoli, Solfatara in 2014 [9] and Stromboli volcano in 2015 [23,24]. As such, although gas-sensing lidars remain far less exploited in volcanology than those targeting volcanic ash/particles [25,26], this novel application field may expand rapidly in the near future.…”

Volcanic Plume CO2 Flux Measurements at Mount Etna by Mobile Differential Absorption Lidar

et al. 2017

Volcanic eruptions are often preceded by precursory increases in the volcanic carbon dioxide (CO 2 ) flux. Unfortunately, the traditional techniques used to measure volcanic CO 2 require near-vent, in situ plume measurements that are potentially hazardous for operators and expose instruments to extreme conditions. To overcome these limitations, the project BRIDGE (BRIDging the gap between Gas Emissions and geophysical observations at active volcanoes) received funding from the European Research Council, with the objective to develop a new generation of volcanic gas sensing instruments, including a novel DIAL-Lidar (Differential Absorption Light Detection and Ranging) for remote (e.g., distal) CO 2 observations. Here we report on the results of a field campaign carried out at Mt. Etna from 28 July 2016 to 1 August 2016, during which we used this novel DIAL-Lidar to retrieve spatially and temporally resolved profiles of excess CO 2 concentrations inside the volcanic plume. By vertically scanning the volcanic plume at different elevation angles and distances, an excess CO 2 concentration of tens of ppm (up to 30% above the atmospheric background of 400 ppm) was resolved from up to a 4 km distance from the plume itself. From this, the first remotely sensed volcanic CO 2 flux estimation from Etna's northeast crater was derived at ≈2850-3900 tons/day. This Lidar-based CO 2 flux is in fair agreement with that (≈2750 tons/day) obtained using conventional techniques requiring the in situ measurement of volcanic gas composition.

“…This particle mass profiling (PMAP) polarization lidar photometer networking (POLIPHON) method can be regarded as one of the basic techniques for detailed height-resolved profiling of optical and microphysical properties of atmospheric particles. Polarization lidars equipped not only with elastic backscatter channels but also with nitrogen Raman channels increase the potential of such a monitoring site by independently measuring vertical profiles of particle backscatter and extinction coefficients (Ansmann et al, 1992;Ansmann and Müller, 2005;Shcherbakov, 2007;Samoilova and Balin, 2008;Pornsawad et al, 2012) and by providing direct observations on the relationship between backscatter and extinction (lidar ratio) for desert dust, volcanic dust, and for layers with mixtures of dust and fine-mode particles (Mattis et al, 2002Pappalardo et al, 2004;Müller et al, 2007;Wang et al, 2008;Tesche et al, 2009aTesche et al, , 2011aWiegner et al, 2011Wiegner et al, , 2012Groß et al, 2011bGroß et al, , 2012Mona et al, 2012;Papayannis et al, 2012;Sicard et al, 2012).…”

Profiling of fine and coarse particle mass: case studies of Saharan dust and Eyjafjallajökull/Grimsvötn volcanic plumes

et al. 2012

View full text Add to dashboard Cite

Abstract. The polarization lidar photometer networking (POLIPHON) method introduced to separate coarse-mode and fine-mode particle properties of Eyjafjallajökull volcanic aerosols in 2010 is extended to cover Saharan dust events as well. Furthermore, new volcanic dust observations performed after the Grimsvötn volcanic eruptions in 2011 are presented. The retrieval of particle mass concentrations requires mass-specific extinction coefficients. Therefore, a review of recently published mass-specific extinction coefficients for Saharan dust and volcanic dust is given. Case studies of four different scenarios corroborate the applicability of the profiling technique: (a) Saharan dust outbreak to central Europe, (b) Saharan dust plume mixed with biomass-burning smoke over Cape Verde, and volcanic aerosol layers originating from (c) the Eyjafjallajökull eruptions in 2010 and (d) the Grimsvötn eruptions in 2011. Strong differences in the vertical aerosol layering, aerosol mixing, and optical properties are observed for the different volcanic events.
