The Vancouver area provides easy access to a wide variety of surfaces and terrain (urban, water, ice, snow, forest, agricultural and alpine). We have also run field campaigns in the United States, Mexico and Europe. The group is amply equipped with instruments to measure most aspects of the atmospheric boundary layer, including turbulence, all the fluxes of heat mass and momentum, profiles of climatic and air pollution elements, soil moisture, stomatal resistance, etc. We also have several towers, data loggers and a very good network of PC and workstation computers.
