Abstract: bservations of carbon dioxide (CO2) mixing ratios in the urban boundary layer (UBL) are rare, even though there is potential for such measurements to be used to monitor city-scale net CO2 emissions. This work presents a ...

Abstract: The Lower Fraser Valley of British Columbia is currently experiencing rapid population growth and episodically suffers elevated oxidant concentrations, the frequency of which is linked to meteorological conditions on the ...

Abstract: Novel use of a commercial, battery-powered, chemiluminescent ozonesonde on a light aircraft is described. This fast-response instrument, originally designed for balloon deployment into the stratosphere, is light, inexpensive, ...

Abstract: Tethersonde, lidar, aircraft, and surface chemistry measurements from an intensive field campaign (Pacific?93) in the Lower Fraser Valley (LFV) demonstrate the daytime advection of pollutants into a lake-filled valley ...

Abstract: The Northern Aerosol Regional Climate Model (NARCM) was used to construct a 44-yr climatology of spring Asian dust aerosol emission, column loading, deposition, trans-Pacific transport routes, and budgets during 1960?2003. ...

Abstract: A 44-yr climatology of spring Asian dust aerosol emission, column loading, deposition, trans-Pacific transport routes, and budgets during 1960?2003 was simulated with the Northern Aerosol Regional Climate Model (NARCM). ...
