Title: Measurements and Analysis of Polarization Data from the ePOP-SuperDARN Experiment.
Abstract: The Radio Receiver Instrument (RRI) onboard the enhanced Polar Outﬂow Probe (ePOP) consists of four 3-metre monopoles in an orthogonal dipole conﬁguration used for observing the polarization of incoming High Frequency (HF) radio wave signals. Propagation of a wave through a ionized medium with an external magnetic field has notable effects on its polarization state through what is known as the Appleton-Hartree equation. Through conjunction with ground-sourced HF signals, RRI data leads to observations of structure in the ionosphere. In the framework of this research, the HF radio waves are sourced by the SuperDARN Saskatoon station. Scientific background and current RRI data results will be presented.
Summer is coming, which means the PEGASUS Student Summer Seminar Series will be starting up again.
Each summer, PEGASUS organizes a seminar series that provides an opportunity for graduate students in the department to share their research and practice their presentation skills in a friendly environment. The audience consists of only graduate and undergraduate students, so the environment is far more relaxed and informal than departmental seminars or conference sessions. Talks are 30-45 minutes long with questions from the audience.
These sessions provide graduate students with the perfect environment to hone their presentation skills, so if you have an presentation in the department or a summer conference you are preparing for, consider taking part.
To claim your spot for this year, message us on our Facebook page, or email your local PEGASUS representative.
Title: Investigation of Solar Influence on Thermospheric Density Variation
Abstract: Due to undulations in the heliospheric current sheet, the Earth’s orbit is divided into sectors where the sun’s interplanetary magnetic field (IMF) at the Earth is primarily directed towards or away from the sun. During the year 2003, the IMF direction at the Earth changes with a nearly consistent periodicity of 12-15 days, leading to well defined IMF sectors. During this same period, thermospheric neutral particle densities and electron content are higher during times when the IMF is directed towards the sun, and lower when the IMF is directed away from the sun. Possible links between the IMF polarity and thermospheric densities were investigated, with a focus on the spatial distribution of thermospheric density variations between IMF sectors, as well as the temporal changes of solar wind and IMF parameters and geomagnetic activity indices during the Earth’s transition between IMF sectors.
