Nature of project: data analysis, theory
Available to students on full-time physics degree schemes only.
The equatorial electrojet is a current jet which flows in the day time along the Earth's geomagnetic equator at 108 km altitude. A new data set has become available, SWARM. The data are a similar format to CHAMP data, however with three satellites in a special configuration, enabling an extra dimension to be added to the analysis. The project requires the student to become familiar with download procedures from ESA. Then using programs already written initial plots to check the data from individual satellites will be analysed. The student will then splice the data and analyse the set in the new dimension. Hodo diagrams of the annual variations of the electrojet will hopefully yield information towards the structure of the electrojet.
A successful project will develop beyond the above in one/some of the following directions:
Continue development of a computer package for reading the archive data to a point where it is useable by anyone.
Develop ideas for analysing the data in a dimension not used before. This requires extensive use of MatLab.
Determine the underlying physics of the structure of the equatorial electrojet.
When considering where to take your project, please bear in mind the time available. It is preferable to do fewer things well than to try many and not get conclusive results on any of them. However, sometimes it is useful to have a couple of strands of investigation in parallel to work on in case delays occur.
Additional scope or challenge if taken as a Year-4 project: Additional depth and understanding of data analysis technique.
Please speak to Heather McCreadie (hem18) if you consider doing this project.
Initial literature for students:
This project will allow the student to create a set of routines to read a specific data base. Using these routines some analysis will be performed. Use of MatLab is required so H. McCreadie's packages can be used.
