EARLINET was following the evolution of the volcanic cloud over Europe in near real time. Quicklook data were sent to the VAAC at the Met Office UK throughout the event.
Quicklooks were available on a webpage of the LMU Munich including links to a large set of other EARLINET stations:
Links to ceilometer-data, though not part of EARLINET, were provided as well to support authorities, press and the public.
Continuous Reporting to VAAC
A report summaring relevant information about the dispersion of the ash-cloud was updated on a daily basis and provided to the VAAC, as an additional source of information (beyond the quicklooks). At the time being the report was not issued in a standardized format - the highest priority was put on a timely delivery.
One of the first talks of the EARLINET activities was given at the EGU 2010 in Vienna on 4. May 2010 in a special session on the Eyjafjallajökull-eruption.

A first overview of active and passive remote sensing of the plume was given by Ansmann et al.: "The 16 April 2010 major volcanic ash plume over central Europe: EARLINET lidar and AERONET photometer observations at Leipzig and Munich, Germany", Geophys. Res. Lett., Vol. 37, L13810, doi:10.1029/2010GL043809, 2010.
Many publications from EARLINET stations appeared on special issues, e.g. Atmospheric Environment, Journal of Geophysical Research, Atmospheric Chemistry and Physics, related to this volcanic eruption.
The 4d distribution of the Eyjafjallajökull plume over Europe as observed by EARLINET is discussed in Pappalardo et al., ACP 2012 http://www.atmos-chem-phys.net/13/4429/2013/ and reported in the Eyja2010 EARLINET Relational database.
