The eruption of the Icelandic volcano Eyjafjallajökull in April–May 2010
represents a "natural experiment" to study the impact of volcanic emissions
on a continental scale. For the first time, quantitative data about the
presence, altitude, and layering of the volcanic cloud, in conjunction with
optical information, are available for most parts of Europe derived from the
observations by the European Aerosol Research Lidar NETwork (EARLINET).
Based on multi-wavelength Raman lidar systems, EARLINET is the only
instrument worldwide that is able to provide dense time series of
high-quality optical data to be used for aerosol typing and for the
retrieval of particle microphysical properties as a function of altitude.
In this work we show the four-dimensional (4-D) distribution of the
Eyjafjallajökull volcanic cloud in the troposphere over Europe as
observed by EARLINET during the entire volcanic event (15 April–26 May
2010). All optical properties directly measured (backscatter, extinction,
and particle linear depolarization ratio) are stored in the EARLINET
database available at http://www.earlinet.org. A specific relational
database providing the volcanic mask over Europe, realized ad hoc for this
specific event, has been developed and is available on request at
http://www.earlinet.org.
During the first days after the eruption, volcanic particles were detected
over Central Europe within a wide range of altitudes, from the upper
troposphere down to the local planetary boundary layer (PBL). After 19 April
2010, volcanic particles were detected over southern and south-eastern
Europe. During the first half of May (5–15 May), material emitted by the
Eyjafjallajökull volcano was detected over Spain and Portugal and then
over the Mediterranean and the Balkans. The last observations of the event
were recorded until 25 May in Central Europe and in the Eastern Mediterranean
area.
The 4-D distribution of volcanic aerosol layering and optical properties on
European scale reported here provides an unprecedented data set for
evaluating satellite data and aerosol dispersion models for this kind of
volcanic events. |
