I have moved !!!

I have now moved to the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, USA. This link goes to my new home page. The material below relates to my time at McGill as a post-doc, the links should still work though.

Hello - welcome to Bill's home page.
I am a postdoctoral researcher in the Atmospheric and Oceanic Sciences Department of McGill University. on the main campus in downtown Montreal (photograph (118kB)).

I'm in the Physical Meteorology group and use a number of remote sensing instruments to study the atmosphere. To get an idea of some of the things I do here, check out my pages on the McGill Radar Meteorology site :-

• The McGill Radar and Weather Data Archive Page.
  Look up radar data for the last year, plus various local soundings, surface obs, ceilometer obs, statellite images, and model analyses. Currently about 20,000 images are available.
• The McGill UHF Wind Profiler, a radar for making wind and temperature profiles of the lower atmosphere.
• Real-time reflectivity and vertical velocity images from the profiler (updated hourly).
• Real-time consensus average winds plot from the profiler (updated hourly).
• Real-time RASS temperature profiles (updated hourly).
• Real-time diagnostic plot from the profiler (new image every 30 seconds - takes a few seconds to generate).
• Real-time ceilometer observations (last 24 hours and latest 30 second profile).
• A study of radar echoes of smoke plumes - you can watch a movie on this page!
• A study of pollution layers trapped by a temperature inversion
• An example of data from our laser ceilometer
• Real-time surface station ozone and particulate matter measurements from AES, McGill users only

Here are three conference proceedings papers I've submitted recently :-

• UHF Echoes at the Base of Elevated Snow Layers
• Gravity Wave and Wind Shear Observations on the McGill Weather and Profiler Radars
• The VHF Wind Profiler at Resolute Bay in the Canadian Arctic; Description and Preliminary Observations.

And here are the abstracts of some publications :-

• Spaced Antenna and Interferometric Velocity Measurements with MF and VHF Radars
• Spaced Antenna Scattering Scale and Orientation Measurements of the Upper Troposphere on the MU Radar
• Frequency Domain Interferometry on Spaced Antenna MF Radar
• Radar Observations of a Major Industrial Fire

In addition to the work I'm doing at McGill, I'm working with Prof Wayne Hocking of the University of Western Ontario on his VHF MST radar at Resolute Bay in the Canadian Artic. Since this instrument has only recently been installed and is still being developed, I don't have any plots or pictures yet.

Prior to coming to McGill I was at the Radio Atmospheric Science Center of Kyoto University in Japan and prior to that I was at the Department of Physics and Astronomy of the University of Canterbury in Christchurch, New Zealand.
