Description

We combine values of column height HTP and mass eruption rate QM, radar derived, including the associated wind velocity (vW) for several eruptive events of Mt. Etna (Italy). Hence, we use a Monte Carlo Markov Chain approach to fit a parametric model relating HTP, QM and vW. The fitted model can then be used to quickly infer QM from observed HTP and vW. An outstanding feature is that HTP and QM are obtained from the same sensor reducing the overall uncertainty.

Technical info (English)

Time trend of the radar-based estimates of the mass eruption rate (QM) and top plume height (HTP) for 32 Etna eruptions and the vw data retrieved from the reanalysis data of the ECMWF for the same events. For each event you can find: Time (UTC), top plume height (km); QM (mass eruption rate (kg/s)). Finally, vw is the wind velocity (m/s).
