Post Doctoral Research Assistant in the measurement and analysis of the mature Hunga-Tonga volcanic cloud
Applications for this vacancy closed on 27 November 2023 at 12:00PM
Applications are invited for a Postdoctoral Research Assistant in the
measurement and analysis of the mature Hunga-Tonga volcanic cloud.
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. This combination does not allow traditional
approaches of independently retrieving gas or particle concentrations. The aim
of this project is to characterise 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 Cross-track
Infrared Sounder (CrIS).
As part of a wider team, the post-holder will create a new retrieval scheme
for determining the particle properties from the IASI and CrIS instruments.
This work will be validated against other satellites (e.g. IASI, MLS, TROPOMI,
Calipso, and ACE), in situ and ground based measurements. These new retrievals
will then be used to study the evolution of the clouds from the Hunga-Tonga
eruption with the aim of trying to better understand the rapid development of
sulphuric acid and the distribution of ash in the stratosphere.
Applicants should possess, or be very close to obtaining a doctorate in
physics or a related field. Previous experience in radiative transfer and the
use of satellite measurements will be an advantage.
Candidates are expected to demonstrate experience in coding preferably using
Python or Fortran.
The post-holder will have the opportunity to teach.
Please direct enquiries about the role to r.grainger@physics.ox.ac.uk
Only applications received before midday 27 November 2023 can be considered.
You will be required to upload a brief statement of research interests, CV and
details of two referees as part of your online application.
