Observations of volcanic SO₂ from MLS on Aura

factors measured in this study will be particularly useful in combination with field and modelling studies to understand the role of surface oxidation on clay minerals and

Error estimates for BrO and SO 2 vertical column densities for the two lines of sight during the observation of the plume (Sect.. Overview of the retrieved BrO and SO 2 mixing

In particular, within the framework of the EU project NOVAC (Network for Observation of Volcanic and.. ) showing the location of Nevado del Ruiz volcano (Colombia) and the three

Correlation coefficients between the mean columnar SO 2 measured by the Brewers in Europe and provided by the satellite products of OMI and GOME-2 during the volcanic eruptions

The first part of the eruption produced a higher plume in terms of amount and altitude, and a lower plume connected with the volcano was present intermittently for all of the pe-

Similar discrepancies are found when using the HYSPLIT trajectory model at different altitudes (10–13 km) or the wind speeds and directions, actually measured on board of the

In our previous studies (Benson et al., 2008; Young et al., 2008), we reported the residual [H 2 SO 4 ] (measured at the end of the nucleation reactor) and further used the

However, in previous field measurements that used a zenith viewing DOAS instrument on a mobile platform, emissions were estimated by first taking a “clean- air” spectrum at some
