Ash dispersion modelling from successive paroxysms of Etna using WRF-Chem and near-source VOLDORAD radar measurements

This dataset contains 4 animated gif files showing WRF-chem atmospheric dispersion modelling of sub-10 micron volcanic ash particles (PM10) emitted by Etna during sequences of explosive paroxysms (from Rizza et al., Remote Sensing 2023). The atmospheric dispersal of sub-10 μm (PM10) ash is modelled using the WRF-Chem model coupled online with meteorology and aerosols and offline with Mass Eruption Rates (MER) and plume heights infered from near-source measurements by the OPGC Doppler radar VOLDORAD-2B (Donnadieu et al., 2015, 2016).
