[Met-jobs] PhD position - Energetic Particle Precipitation in the Middle Atmosphere

From Jia Jia <>
Date Fri, 9 Mar 2018 07:47:39 -0500

PhD student in “Effects of Energetic Particle Precipitation in the Middle Atmosphere” at Sodankyla Geophysical Observatory, Finland

The University of Oulu in Northern Finland, with approximately 16,000 students and 3,000 employees, is an international, multidisciplinary research university with a rich pool of creative and intellectual talent.

Sodankyla Geophysical Observatory ( is a separate institute of the University of Oulu. Established in 1914, SGO carries out continuous, long-term geophysical measurements of Earth’s high-latitude environment.

The PhD position is part of the project "Mesospheric Monitoring of Ozone above the Polar Vortex (MeMO)”. There is growing evidence that the energetic particle precipitation (EPP) originating from the Sun can significantly modulate the middle-atmospheric dynamics, and possibly alter the global atmospheric circulation via ionic production of minor species (such as odd hydrogen and odd nitrogen), thus causing subsequent ozone loss in the stratosphere. 

The PhD project investigates both the EPP and the photoionisation taking place in the mesosphere-lower thermosphere (MLT) altitudes (mainly 60-100 km). For the EPP, the altitude of the maximum ionisation is a direct measure of precipitation energy. This energy-height dependence makes it possible to invert the EPP flux density spectrum from any height-dependent electron density measurement.

The successful candidate will have a M.Sc. degree in physics, space physics, atmospheric physics or geophysics. Experience in data analysis using a high-level programming language (e.g. Python, Matlab) is highly beneficial. Excellent command of both spoken and written English is essential.

The PhD position is for 4 years from 1st May 2018 (unless agreed otherwise).

Apply online latest on Friday, 16th March 2018.
