The ash dispersion over Europe during the Eyjafjallajökull eruption - Comparison of CMAQ simulations to remote sensing and air-borne in-situ observations
International audience The dispersion of volcanic ash over Europe after the outbreak of the Eyjafjallajökull on Iceland on 14 April 2010 has been simulated with a conventional three-dimensional Eulerian chemistry transport model system, the Community Multiscale Air Quality (CMAQ) model. Four differe...
