Journal ArticleDOI
A model study of the pollution effects of the first 3 months of theHoluhraun volcanic fissure: comparison with observations and air pollutioneffects
TL;DR: In this article, the authors present results from EMEP/MSC-W model simulations to which they added 750 kg/s−1 ǫSO2 emissions at the Holuhraun plain from September to November (SON), testing three different emission heights.

TL;DR: The European Natural Airborne DisasterInformation and Coordination System for Aviation (EWS) prototype early warning system as mentioned in this paper was developed to produce alerts of airborne hazards (volcanic, dust, smoke and radionuclide clouds), satisfying the requirement of aviation air traffic management stakeholders.
Journal ArticleDOI
Volcanic SO2 by UV-TIR satellite retrievals: validation by using ground-based network at Mt. Etna
Claudia Spinetti,Giuseppe Salerno,Tommaso Caltabiano,Elisa Carboni,Lieven Clarisse,Stefano Corradini,Roy G. Grainger,Pascal Hedelt,MariLiza Koukouli,Luca Merucci,Richard Siddans,Lucia Tampellini,Nicolas Theys,Pieter Valks,Claus Zehner +14 more
TL;DR: In this article, the SO2 measurements retrieved by MODIS, hyper-spectral infrared Atmospheric Sounding Interferometer (IASI) and the second Global Ozone Monitoring Experiment (GOME-2) data are compared with the ground-based data from the FLux Automatic MEasurement monitoring network (FLAME).
Atmospheric bromine monoxide: multi-platform observations and model calculations
TL;DR: In this article, the authors describe remote-sensing observations of bromine monoxide (BrO) derived from scattered sunlight spectra in the ultraviolet region measured by ground-based multi-axis and satellite nadir viewing instruments.
