Earths dynamic Radiation Belts NASA

Project Background:

The Earth's Outer Radiation Belt is a region of near-Earth space containing high-energy charged particles that are trapped by the geomagnetic field. Whilst we know that the radiation belt environment is ultimately driven by the solar wind, it is very challenging to model these particle populations.

The myriad socio-economic risks posed by space weather effects are reflected through its inclusion in the UK Cabinet Office National Risk Register for Civil Emergencies. Accurate modelling and prediction is essential for safeguarding the operational satellites in orbit that underpin modern society - placing a growing reliance on forecasts such as those based on the world-leading model developed at the British Antarctic Survey. This model is now being incorporated into the UK MET Office Space Weather Forecasting Suite - one of 3 space weather prediction centres worldwide. • Existing radiation belt modelling and forecasting capabilities rely upon techniques that treat electromagnetic waves determining the electron dynamics as having very small amplitudes. However, recent satellite datasets have demonstrated the prevalence of large amplitude (aka ‘nonlinear’) electromagnetic waves. Understanding the impact of nonlinear waves on space weather modelling is one of the biggest international challenges in radiation belt science today. 

Project Aims and Methods:

In this PhD you will work towards making internationally significant discoveries about the importance of nonlinear waves in radiation belt and space weather modelling – to ultimately improve forecasting. Once you become comfortable with the underlying science and general direction, you will be invited to help guide the project towards a particular aspect that most interests you. This could be using one or more of theoretical, numerical or observational approaches – depending on your inclinations and the questions that we identify together.

You will have the opportunity to lead on a project that will make an important contribution to an internationally significant scientific problem with real-world application.  You will work and collaborate within a strong UK-based network of world-leading experts in Space Weather and Space-science. The ultimate aim of this PhD is to support you to become an independent researcher, and a valued colleague in whatever future role you choose.  

Candidate Requirements:

A background in physics, applied mathematics or closely-related mathematics/physics science. Prior knowledge of space/plasma physics or computer programming are not necessary. 

Project Partners:

Dr Oliver Allanson (OA) is leading a NERC research programme (2021-‘26) to understand the importance of nonlinear physics in radiation belt modelling. Dr Nigel Meredith (NM) is a world-leading authority on the analysis of particle and electromagnetic wave data from spacecraft. We have collaborations and partnerships with scientists at numerous universities and research institutes around the world, and will be delighted to invite the candidate into these networks and discussions.

Training:

In addition to regular one-to-one meetings with supervisors, you will be encouraged to participate in wider group- and network- activities to build up your academic profile and collaborate with colleagues. You can attend seminars from national and international experts in the field, and benefit from national and international conferences and summer schools that develop both discipline-specific and transferable skills (e.g. AGU Fall meeting and International School/Symposium for Space Simulations) • The GW4+ DTP provides many further training and skills development opportunities, https://www.nercgw4plus.ac.uk/

Prospective applicants: For information about the application process please contact the Admissions team via pgrenquiries@exeter.ac.uk.  

Each project advertisement has an ‘Apply Now’ button linking to an application portal. 

Please note that applications received via other routes including a standard programme application route will not be considered for the studentship funding.  

Eligibility

NERC GW4+ DTP studentships are open to UK and Irish nationals who, if successful in their applications, will receive a full studentship including payment of university tuition fees at the home fees rate.

A limited number of full studentships are also available to international students which are defined as EU (excluding Irish nationals), EEA, Swiss and all other non-UK nationals.  For further details please see the NERC GW4+ website.

Those not meeting the nationality and residency requirements to be treated as a ‘home’ student may apply for a limited number of full studentships for international students. Although international students are usually charged a higher tuition fee rate than ‘home’ students, those international students offered a NERC GW4+ Doctoral Training Partnership full studentship starting in 2022 will only be charged the ‘home’ tuition fee rate (which will be covered by the studentship). 

International applicants need to be aware that you will have to cover the cost of your student visa, healthcare surcharge and other costs of moving to the UK to do a PhD. More information on this is available from the universities you are applying to (contact details are provided in the project description that you are interested in.

The conditions for eligibility of home fees status are complex and you will need to seek advice if you have moved to or from the UK (or Republic of Ireland) within the past 3 years or have applied for settled status under the EU Settlement Scheme.
 


 

 

Entry requirements

Applicants should have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK.   Applicants with a Lower Second Class degree will be considered if they also have Master’s degree.  Applicants with a minimum of Upper Second Class degree and significant relevant non-academic experience are encouraged to apply.
