Science project 1: Volcanic plume evolution and injection profiles (VolPlume)
The project VolPlume will focus on the initial plume development in the first few hours to days of a volcanic eruption by combining state-of-the-art atmospheric modelling and satellite remote sensing. The project will create the important capability to quickly carry out similar studies for future volcanic eruptions. This includes both the modelling framework and the satellite data retrieval algorithms. The project will also provide some of the model development and initial conditions relevant for the entire research unit. Project VolPlume will, e.g., address the research the following research questions:
- What are the crucial processes that control the physicochemical evolution of volcanogenic emissions within the eruption plume?
- How well can state-of-the-art models reproduce the effect of moist convection on the development of the eruption plume and volcanogenic H2O injections into the stratosphere?
