Applications are invited for a Postdoctoral Research Assistant in   satellite remote sounding and analysis of the initial Hunga-Tonga volcanic cloud.

 

The post is available initially for a fixed-term duration of 2 years 8 months.

 

The aim of this project is to characterise the eruption and the initial evolution of the volcanic plume (first 48 hours)  from satellite data complemented by measurements of lightning (WWLLN), ionospheric waves, surface seismic waves and atmospheric pressure waves (from surface stations and radiosondes). It is expected that this work will lead to fundamental papers on the formation of volcanic clouds and their interaction with the atmosphere.

 

The principal task of the project is to characterise the ash, ice and sulphuric acid formed by the Hunga-Tonga  eruption by applying the Optimal Retrieval of Aerosol and Cloud (ORAC) algorithm to imager data  (Himawari, GOES, SLSTR, VIIRS, MODIS) accounting for the high-levels of water vapour and sulphur dioxide.

 

The successful candidate will develop a high resolution atmospheric radiative transfer model using existing transmission (The RFM) and multiple scattering (e.g. DISORT) code.  This code will be used to simulate top-of-atmosphere radiance (0.5 - 16 um) for a range of volcanic plume structures and compositions. This dataset will be used to compare different volcanic cloud satellite retrievals.

 

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 8 January 2024 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.

Recent publications http://eodg.atm.ox.ac.uk/group/eodg/publications_papers.html The role 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 eruption and the initial evolution of the volcanic cloud (first 48 hours) from satellite data complemented by measurements of lightning (WWLLN), ionospheric waves, surface seismic waves and atmospheric pressure waves (from surface stations and radiosondes). It is expected that this work will lead to fundamental papers on the formation of volcanic clouds and their interaction with the atmosphere. Initially this will involve developing a high resolution atmospheric radiative transfer model using existing transmission (The RFM) and multiple scattering (e.g. DISORT) code. This code will be used to simulate top-of-atmosphere radiance (0.5 - 16 um) for a range of volcanic plume structures and compositions. This will contribute to a simulated dataset which will be used to compare different volcanic cloud satellite retrievals. The principal task of the project is to characterise the ash, ice and sulphuric acid formed by the Hunga-Tonga eruption by applying the Optimal Retrieval of Aerosol and Cloud (ORAC) algorithm to imager data (Himawari, GOES, SLSTR, VIIRS, MODIS) accounting for the highlevels of water and sulphur dioxide. This may involve making modifications to the retrieval code. These new measurements will be complemented by data from other instruments such as IASI, MLS, TROPOMI, Calipso, and ACE, as well as ground-based observations and in-situ measurements. The focus of this study is on the cloud formation and transient atmospheric effects during the first hours of the eruption. Responsibilities   Contribute to the creation of a simulated top-of-atmosphere radiance (0.5-16 µm) database to be used for testing volcanic cloud satellite retrievals Adapt existing ORAC retrieval scheme to improve its performance for the HT-HH eruption  Apply the ORAC retrieval to data from several satellite instruments (e.g. Himawari, GOES, SLSTR, VIIRS, MODIS) to study plumes from the HT-HH in the first few days after the eruption occurs.  Compile information about the HT-HH eruption and plumes from a variety of sources including satellites, ground-based instruments and in-situ measurements, with the aim of better appreciating the sequence of events, plume dynamics and atmospheric impacts.  Presentation of results at national and international meetings and their publication in highimpact peer-reviewed journals  Contribution to the intellectual life of the Earth Observation Data Group, including meetings and collaborations, as required  The post-holder will have the opportunity to teach. This may include lecturing, small group teaching, and tutoring of undergraduates and graduate students. Selection criteria  PhD (or close to obtaining) in physics or related fields. 169962 jd-and-person-spec-physics-mar23-HTHH-A.doc 2  Curiosity and ability to analyse complex phenomena demonstrated by a doctorate (or close to obtaining a doctorate) in physics or a related field.  An understanding of radiative transfer including scattering  An ability to present scientific results clearly and concisely, both verbally and in written form.  Programming experience (e.g. python) Desirable selection criteria  Computing skills, e.g. knowledge of UNIX/Linux and experience with Fortran  Demonstrated drive and ability to perform novel research of international standing.  A record of presenting scientific results in meetings and international conferences Pre-employment screening Standard checks If you are offered the post, the offer will be subject to standard pre-employment checks.
