The post is available initially for a fixed-term duration of 2 years. The eruption of Hunga-Tonga in January 2022 generated a volcanic cloud of enhanced concentrations of water and sulphur dioxide combined with particles of ash, ice and sulphuric acid.

The aim of this project is to characterise the of the ash and sulphuric acid volcanic clouds (> 48 hours) from high resolution infrared instruments such as the Infrared Atmospheric Sounding Interferometer (IASI) instruments and the Crosstrack Infrared Sounder (CrIS). Traditional approaches for retrieving gas and particle concentrations are not sufficient for studying the unusual plumes from the Hunga-Tonga eruption.
