Description:
Envisat MERIS and AATSR data have been acquired in
the framework of the Eurorisk-Preview project. The
project addresses European civil protections and
proposes to develop, at the European scale, new
information services to support the risk management. In
Italy one of the most important natural risks is due to
the presence of volcanoes. Mt. Etna in Sicily, displays
persistent activity, periodically interrupted by eruptions,
which emit volcanic aerosol and ash to different
altitudes in troposphere affecting the central
Mediterranean area. In order to test the use of MERIS
and AATSR data to derive emitted particles parameters
as optical depth, effective radius and the ash mass of
particles, the already developed remote sensing
techniques has been adapted. MERIS and AATSR data
acquired during the Mt. Etna 2002-2003 volcanic
eruption has been chosen.
The use of VIS and TIR bands of the two sensor
demonstrates the potential to derive useful information
on plume particles and to monitor the volcanic plume
during eruption if frequent and high resolution data is
available in near real time.
