(MERI) SO2 flux time series calculated from TROPOMI imagery

Scientific progress is most effective when combining observations, experiments and models, however empirical observations are most critical as these reflect the natural system directly. When a new source of observational data becomes available it can lead to a step change in our understanding of the observed system, if a focussed effort is made to fully realise the potential of the new data. In October 2018 such a new global source of data will be available which has the potential to revolutionise how we understand volcanic degassing on Earth and shed new light on all the processes described above. These data will be provided by the TROPOMI instrument, aboard the Sentinel-5P satellite (Theys et al., 2017). The objective of this project is to realise the full scientific potential offered by the new data.

This project will require fieldwork in Italy and other countries on active volcanoes, and full training will be provided on working in volcanic environments. We will use a variety of methods, but remote sensing and radiative transfer modelling is key to the project. Validation activities with partners in INGV Catania are essential for the projects success. We will build on the methods used by Pardini et al. (2018) to calculate SO2 flux time series from global volcanic sources. This work will open new scientific frontiers on degassing as a global process as well as eruption forecasting.

We seek an able and enthusiastic individual with a strong background in geoscience or physical science to join our volcanology research group. The project will suit a numerate candidate with enthusiasm for field studies and analytical/experimental work. At the end of the project, the student will have gained a broad range of practical, intellectual and interpersonal skills, opening multiple career opportunities, from academia to industry or government roles.
