The development of meteorological information for regional studies in valley and shoreline locations involves measurement and modelling studies of the flow regimes and dispersal characteristics, and subsequent modelling of contaminant dispersion. CEMC has conducted the following studies:

Hat Creek, British Columbia

CEMC carried out a study of the complex flows in the Hat Creek, BC mountain valley using minisonde and tetroon instruments, as well as surface and tower observations for BC Hydro. This involved setting up a meteorological network to determine the slope flows and circulation flows within the valley and their interaction with the flows outside the valley, and involved 4 seasonal campaigns to characterize the detailed flow structures.

Teck Lead Smelter, Trail

We carried out a study of the valley flows within the Columbia Valley at Trail and developed a model to simulate dispersion of sulphur dioxide in the complex flow regimes for the Teck Lead Smelter.

Nanticoke and Lakeview Power Plants, Ontario

We carried out field studies to characterize the shoreline dispersion environment at Lake Erie, and developed a Shoreline Fumigation Model to predict the impact of the OPG thermal power plants at Nanticoke and Lakeview.
