Personal and ambient exposure to PM2.5 in the
Prince George Airshed
With Melanie Noullett (MSc candidate) we are using personal
exposure monitors to measure both outdoor and personal
exposure of school children to PM2.5 in Prince George,
B.C. The field phase of the study was completed in mid-March
2001, and we are presently analysing the samples.
Gap flows (North Foehn) in the Eisack valley during MAP
I participated in the Special Observing Period of the
Mesoscale Alpine Programme (MAP) in Innsbruck Austria
between August and December 1999. I deployed a new Scintec FAS64
Doppler Sodar system and three surface stations near
Sachsenklemme in the Eisack Valley, South Tirol Italy, in
order to observe hydraulic-like flow conditions during north
Foehn events. Click here

Numerical Modelling of Coastal Trapped Disturbances
Utilizing a 3D mesoscale numerical atmospheric model - RAMS - we are simulating both
realistic and idealized examples of CTDs with the eventual aim of understanding
the effects of boundary conditions and complex coastal terrain on CTD
propagation. With Dr. C. Reason (University of Melbourne), Dr. S. Guan
(PDF, formerly UNBC), Dr. Kevin Tory (PDF, formerly UNBC),
H. Fu (MSc, formerly UNBC), this work is funded by the US ONR, and AES/NSERC.
Wind Throw Prone Areas in the McGregor Model Forest
Analysis of existing data, collection of new data from a network
of five weather stations, and numerical modelling using CSU RAMS are
being applied to assess areas in the MMF prone to wind throw (trees
knocked down by strong wind events). With B. Murphy (MSc, UNBC), this
work was being funded by the Mcgregor Model Forest Association.
Transport and Dispersion of Pollutants in Valleys
A Doppler Sodar system in Prince George, mesoscale numerical modelling
using RAMS, modelling using Calmet/Calpuf, and synoptic
climatology methods, are being used to characterize
air pollution episodes in central BC valleys. With P. Willis
(MSc, UNBC), B. McEwen (MSc, UNBC) and M. Noullett (MSc, UNBC)
the eventual aim of this work is to provide guidance for managers in air
quality monitoring, land use planning, and in managing air pollution episodes.
Satellite Imagery Characterization of Explosive Marine Cyclogenesis
Statistical analysis of geostationary satellite imagery is being
used to characterize marine "bombs" with the goal of developing automatic
forecasting algorithms for early detection of these storms. With B.
Pierce (MSc, UNBC), this work is funded by AES/NSERC.
Beaufort Sea Coastal Trapped Disturbances
An observational program utilizing four pressure and temperature
sensors deployed between Shingle Point, Komakuk Beach, and Old Crow
Yukon, and Pump 2 south of Prudhoe Bay Alaska, was mounted in 1994-95.
The aim is to determine whether or not coastal trapped disturbances
occur in the region. With C. Kubu (MSc, UWO) this work is funded by
AES. For more information see the BASE home page.
Climatology of UVB radiation in Canada
Data collected by The Weather Network's national network
of 24 broad-band Ultra-Violet B sensors has been analysed. Spatial extent
and causes of a very high UVB episode are discussed and the broadband
sensors are validated by comparison with a Brewer spectrophotometer.
With H. Krzeminska (MSc, UWO) and R. Lowe (UWO Physics), this work was
partially funded by AES/NSERC.
