Abstract
We propose to install passive VHF radar receivers in Canada in order to study field aligned irregularities in the E region at auroral latitudes. The proposed research addresses four goals: (1) to create a dedicated radar instrument which continuously provides high quality data from 1.5 meter irregularities in the auroral zone, (2) to use this instrument to study the temporal and spatial evolution of auroral electrojet irregularies, (3) to improve the capabilities of the passive VHF radar technique, and (4) to provide a rich educational and research experience for undergraduate and graduate students. Our planned site will provide nearly common volume view of our 100 MHz instrument with Canadian radars at 50 and 44 MHz , as well as additional magnetometers and optical instruments. In addition to studying electrojet irregularies, we will be able to observe the development of subauroral polarization jet which has been identified by scientists using the incoherent scatter radar at Millstone Hill. We will routinely observe meteor trails, and we may also be able to detect polar mesospheric summer echoes at 51 degrees geographic latitude.
