[PEGASUS] Summer Seminar Series: Fraser Hird

Please join us this Tuesday, July 11 in Physics 175 for our next presentation in our PEGASUS Summer Seminar Series.
Our next speaker is Fraser Hird, who works with the ePOP-SuperDARN Experiment.
There will be cookies and refreshments served beforehand at 3:00 pm in the lounge for those attending the seminar.

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.

[PEGASUS] Summer Seminar Series: Kimberlee Dube

Please join us this Tuesday, July 4 in Physics 175 for our next presentation in our PEGASUS Summer Seminar Series.
Our next speaker is Kimberlee Dube, who studies ozone and aerosol profiles using OSIRIS.
There will be cookies and refreshments served beforehand at 3:00 pm in the lounge for those attending the seminar.
Title: The effect of solar rotation on OSIRIS ozone and aerosol observations 
Abstract:
The amount of solar radiation reaching the Earth’s atmosphere varies with both the 11 year solar cycle and the 27 day solar rotation period. The Optical Spectrograph and InfraRed Imager System (OSIRIS) has been in orbit on the Odin satellite since late 2001. The effect of solar UV variability on ozone and aerosol profiles retrieved from OSIRIS was investigated for a 14 year period. Current results will be presented and compared with those from other limb instruments.
