Atmospheric science in the Canadian Arctic and a new mm-wave radiometer from the University of Toronto

A new millimetre-wave radiometer, SPÉIR, is being developed at the University of Toronto in order to make measurements of atmospheric trace gases involved in Arctic ozone chemistry. SPÉIR will join a number of instruments already in operation at the Polar Environment Atmospheric Research Laboratory (PEARL), situated in Eureka, Nunavut, Canada (80N 86W). The measurements from PEARL are used extensively by The Canadian Network for the Detection of Atmospheric Change (CANDAC) to evaluate the composition, chemistry, and dynamics of the atmosphere above Eureka.
I will talk about the objectives of CANDAC and the work being done at the University of Toronto, including some recent validation campaigns to Eureka. I will describe the new radiometer: its design, simulated performance, and how it fits into the goals of CANDAC. Finally I will talk a little about a collaborative project by IRF and the University of Toronto and what I will be doing in Kiruna this month!
