Long-term research goals have been primarily directed at understanding meteorological phenomena that develop in regions of complex, urbanized terrain. An important applied focus of this work has been the investigation of the role such phenomena (e.g. land sea breezes, slope winds and urban effects) have on the transport and dispersion of pollutants. Although much of this research has been site-specific (e.g. the Lower Fraser Valley, British Columbia) the findings are of general interest. Considerable progress has been made in understanding the processes contributing to, and the three-dimensional distribution of, air pollution in regions of complex terrain. This observational program has provided important information for development, initialization and validation of numerical models designed to forecast air quality and test pollutant abatement strategies. Recently, this research thrust has broadened to consider the impact of long-range transport of burgeoning pollutant emissions and crustal dust from Eurasia to North America. A central part of this work has been the installation of a state-of-the-art lidar facility at UBC in collaboration with Environment Canada.
