Aerosol properties of the Eyjafjallajokull ash derived from sun photometer and satellite observations over the Iberian Peninsula
The Eyjafjallajökull ash that crossed over Spain and Portugal on 6-12 May 2010 has been monitored by a set of operational sun photometer sites within AERONET-RIMA and satellite sensors. The sun photometer observations (aerosol optical depth, coarse mode concentrations) and ash products from IASI and...
