Current research and/or projects

Development of air quality models for the assessment of emission management approaches and forecasting

  • Development of sulphur and nitrogen species source-receptor matrices (SRMs) for North America using Lagrangian chemical transport models
  • Evaluation and comparison of air quality model predictions with measurements
  • Preparation of emission data sets for air quality models using the SMOKE emissions processing system

Professional activities / interests

Generated new sulphur-species SRMs for 1990 for 40 emission regions and 200 receptors; results contributed to Chapter 4 of 2004 Canada Acid Deposition Science Assessment

Developed and evaluated a new Lagrangian chemical transport model named LIAM (Lagrangian Inorganic Aerosol Model) to model sulphur, oxidized nitrogen, and reduced nitrogen concentration and deposition.

Evaluated 2002 quarterly and annual performance of AURAMS, a regional particulate-matter chemical transport model, using measurements from all available Canadian and U.S. air-chemistry and precipitation-chemistry monitoring networks

Investigated aqueous-chemistry solver for aqueous-phase chemistry mechanism
