Dual-FOV Raman and Doppler lidar studies of aerosol-cloud interactions : Simultaneous profiling of aerosols, warm-cloud properties, and vertical wind
(2014-05-16)
For the first time, colocated dual-field of view (dual-FOV) Raman lidar and Doppler lidar observations (case studies) of aerosol and cloud optical and microphysical properties below and within thin layered liquid water ...
Assessing lidar-based classification schemes for polar stratospheric clouds based on 16 years of measurements at Esrange, Sweden
(2014-02-16)
Lidar measurements of polar stratospheric clouds (PSCs) are commonly analyzed in classification schemes that apply the backscatter ratio and the particle depolarization ratio. This similarity of input data suggests comparable ...
Volcanic ash over Scandinavia originating from the Grímsvötn eruptions in May 2011
(2012-05-16)
A volcanic ash plume that originated from the eruptions of Iceland's Grímsvötn volcano in May 2011 was observed over the Nordic countries using a combination of satellite observations and ground-based measurements. The ...
Ice formation in ash-influenced clouds after the eruption of the Eyjafjallajkull volcano in April 2010
(2011-10-27)
The influence of volcanic ash on heterogeneous ice nucleation in tropospheric clouds is investigated on the basis of 90 observed cloud cases. The clouds were observed with polarization lidars at the two central-European ...
Ash and fine-mode particle mass profiles from EARLINET-AERONET observations over central Europe after the eruptions of the Eyjafjallajökull volcano in 2010
(2011-01-01)
A combined lidar-photometer method that permits the retrieval of vertical profiles of ash and non-ash (fine-mode) particle mass concentrations is presented. By using a polarization lidar, the contributions of non-ash and ...
Air mass modification over the Europe : EARLINET aerosol observations from Wales to Belarus
(2004-12-27)
For the first time, the vertically resolved aerosol optical properties of western and central/eastern European haze are investigated as a function of air mass transport. Special emphasis is put on clean maritime air masses ...
European pollution outbreaks during ACE 2 : Microphysical particle properties and single-scattering albedo inferred from multiwavelength lidar observations
(2002-08-06)
We present vertically resolved physical particle properties and the single-scattering albedo at 532 nm of pollution plumes advected from the European continent out over the Atlantic Ocean. The parameters follow from the ...
