Brief CV

Previous Projects:

I was the Principal Investigator for this project, which involved the launch of high-altitude balloons from Vanscoy, Saskatchewan in 1998, 2000, 2002, and 2004. Each carried a payload of instruments to measure vertical concentration profiles of stratospheric trace gases. The data have been used to investigate the changing chemical balance of the mid-latitude stratosphere, focussing on ozone, and nitrogen and chlorine compounds that play a role in ozone chemistry. This project was a large collaborative effort involving Co-Investigators from Environment Canada (formerly the Meteorological Service of Canada), the University of Toronto, York University, the University of Waterloo, the University of Denver, the Service d'Aeronomie, CNRS (France), and Scientific Instrumentation Limited. MANTRA was supported by the Canadian Space Agency, Environment Canada, NSERC, and CRESTech.

Current Projects:

CANDAC and PEARL

I am one of the founding members of CANDAC - the Canadian Network for the Detection of Atmospheric Change. This is a group of university researchers, led by Prof. Jim Drummond who joined together in 2002 with the objective of improving the state of remote sounding research in the atmosphere in Canada. One of the first priorities of this group was to establish an Arctic laboratory, and in 2004 we were successful in obtaining funding from CFI to equip the Polar Environment Atmospheric Research Laboratory (PEARL) at an existing facility at Eureka, Nunavut that is being leased from Environment Canada. I am leader of the Arctic Middle Atmosphere Chemistry research theme, and mentor for three of the new instruments being installed PEARL (a Bruker IFS125HR Fourier transform spectrometer, a UV-visible grating spectrometer, and an Atmospheric Emitted Radiance Interferometer). Our goal is to provide a long-term dataset for studying the evolution of Arctic atmospheric chemistry and its interannual variability. In 2010, we began a new six-year NSERC CREATE Training Program in Arctic Atmospheric Science, for which I am the Director.

The Canadian Space Agency's Atmospheric Chemistry Experiment (ACE) was launched on SCISAT-1 on August 12, 2003, carrying two instruments: a Fourier Transform Spectrometer (ACE-FTS) and Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO). The primary goal of the mission is to measure and to understand the chemical and dynamical processes that control the distribution of ozone in the upper troposphere and stratosphere, with a focus on the decline of stratospheric ozone at northern mid-latitudes and in the Arctic. I am a Co-Investigator on the mission, as well as Co-Leader of the ACE validation effort. My interests lie in validation activities and interpretation of the satellite data in terms of stratospheric processes. As part of this validation effort, I am also Co-Leader of the ACE Arctic Validation Campaigns which have taken place at Eureka, Nunavut each polar sunrise since 2004. Students and PDFs from my group also participated in the testing and calibration of MAESTRO and ACE-FTS which took place in February-March 2003 at the University of Toronto's Space Instrument Characterization Facility.

The University of Toronto Atmospheric Observatory (TAO)

We have been operating a high-resolution ABB Bomem DA8 Fourier transform infrared spectrometer at the University of Toronto Atmospheric Observatory (TAO) since October 2001, with routine measurements since May 2002. This instrument is used to record solar absorption spectra on a daily basis for long-term measurements of stratospheric and tropospheric trace gases, urban pollution and mid-latitude atmospheric chemistry studies, and satellite data validation. The TAO FTS meets the requirements of the international Network for the Detection of Atmospheric Composition Change (NDACC), allowing the absorption lines of about 30 molecules and isotopes, including ozone, chlorine reservoirs, nitrogen- and carbon-containing compounds, and dynamical tracers to be distinguished. TAO was approved as a Complementary Measurement Station by the NDACC Steering Committee in March 2004, based on the results of a refereed algorithm and data comparison exercise. TAO has received support from the University of Toronto, CFI, ORDCF, CRESTech, NSERC, ABB Bomem, CFCAS, and PREA.

Ground-Based UV-Visible Remote Sounding of the Stratosphere

Although the general mechanism for stratospheric ozone loss is now known, questions remain regarding the underlying chemical and dynamical processes, the potential for severe depletion in the Arctic, and the mechanisms for mid-latitude ozone loss. In order to address some of these questions, we have assembled a portable ground-based instrument to record UV-visible spectra of sunlight scattered from the zenith sky. A telescope can also be optically coupled to the spectrometer to allow night-time measurements using stars as sources of light. The resulting spectra are analyzed to retrieve vertical columns of ozone, NO₂, OClO, and BrO using differential optical absorption spectroscopy, as well as vertical profiles of NO₂. The instrument has been deployed on the ground during the four MANTRA campaigns and in springtime Arctic campaigns every year since 1999. All of the latter were at Environment Canada's former Arctic Stratospheric Observatory (now PEARL) at Eureka, Nunavut (80N), with one at Resolute Bay in 2002. This research is supported by NSERC, CFCAS, MSC, CSA, the Northern Scientific Training Program, and the Canadian Northern Studies Trust.

Ultraviolet-Visible-Infrared Laboratory Spectroscopy

A facility for laboratory spectroscopy in support of atmospheric remote sounding has been constructed for the measurement of absorption features of gases of atmospheric interest at high spectral resolution and over a range of temperatures. Several gas absorption cells, along with transfer optics and a cooling system, have been designed and built, and can be coupled to an ABB Bomem DA8 Fourier transform interferometer capable of operation at UV, visible, and IR wavelengths. Infrared spectra of CO have been obtained to demonstrate the thermal, vacuum, and optical performance of the our coolable 1.5-m cell, and we have also recently measured the infrared cross sections of the fluorotelomer alcohols 1:2, 4:2 and 6:2 FTOH, in a collaboration with colleagues at Ford Motor Company and Dupont Central Research and Development. We are currently working on the infrared spectroscopy of CFC-113, in support of the ACE mission. This project is supported by NSERC and the Canadian Space Agency.

Stratospheric Science with the Odin Satellite

Odin is a small satellite launched on February 20, 2001, that is being used for both aeronomy and astronomy. The Odin project is a collaboration between Sweden, Canada, France, and Finland, with the satellite developed by the Swedish Space Corporation. Odin carries two instruments, a Sub-Millimetre Radiometer (SMR) and a Canadian instrument called OSIRIS (Optical Spectrograph and InfraRed Imaging System). One goal of the Odin mission is to investigate polar and mid-latitude ozone depletion by making global measurements of trace species. I was involved in developing algorithms for the simulation of measurements and for the inversion of data to retrieve vertical concentration profiles from OSIRIS spectra of sunlight scattered from the Earth's limb. We are currently comparing Odin data with other measurements to study the chemical and dynamical processes that determine stratospheric composition.
