We will examine the state of the art in retrieval of volcanic gas, aerosol and ash emissions from volcanoes using satellite data. With new instruments to be launched this is an exciting period for satellite observations of volcanic emissions and new techniques are showing promise in how to maximize the information potential of these data.

The use of such observations to constrain and inform dispersion models for timely warning of potential hazards is a challenging area of ongoing research and one where multi-disciplinary collaboration is important.

Recent advances have highlighted the potential for time series retrieval from combining data from multiple satellite images. Combination of these data with simulations of gas and ash dispersion is key to validating such approaches, as well as understanding how they could be utilized within operational environments.

We encourage submissions focusing on new datasets produced by satellite remote sensing (including time series of gas and particulate emissions), the validation of new and existing methods, and the challenges that remain in detection and quantification of volcanic emissions. Abstracts presenting novel techniques for observing volcanic emissions from air- and space-based instruments and for the integration of such observations in dispersion modelling are particularly welcome.
