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 ...
