[ES_JOBS_NET] Fully-funded PhD at university of Exeter: volcanic impacts on historical climate

[Thomas Aubry]

Dear colleagues,



I am writing to advertise a fully-funded PhD project at the University of
Exeter to work with me on historical volcanic impacts on climate, in
collaboration with Jane Mulcahy (UK Met Office) and Paul Griffiths (University
of Bristol). We very much welcome applicants with strong background in
physics/mathematics even if they have no specialist background in
volcanology and climate science.


*Full details:* https://www.exeter.ac.uk/study/funding/award/?id=5404

*Application deadline: *13th January 2025

*Project description: *Historical (1850-present) climate simulations are
crucial to evaluate climate models on which future climate projections
rely, as well as to disentangle the contributions of anthropogenic and
natural forcings to past climate change. One of the most important natural
forcings is stratospheric aerosols injected by explosive volcanic eruptions
which cool climate globally. Whereas large magnitude eruptions are well
reconstructed, smaller but more frequent eruptions are very poorly
constrained before 1979, the beginning of the satellite era. Yet, these
small-magnitude eruptions contribute half of the total aerosol emissions,
suggesting a crucial bias in the last generation of climate model
simulations.  In this project, the student will leverage a novel inventory
of small-magnitude eruptions to produce the first ensemble of historical
climate simulations with a holistic representation of volcanic eruptions.
They will run these simulations with the latest version of the UK Earth
System Model (UKESM), the UK’s flagship climate model, and work hand in
hand with the UK Met Office and international partners. The analysis of
these simulations will quantify the impact of small eruptions on historical
temperatures, precipitations and on key modes of climate variability. It
will also illuminate the importance of pre-satellite era biases in our
climate forcing datasets.


Please email me if you have any questions!


All the best,


Thomas
