Research Scientist

Research scientist in the meteorological research division specializing in remote sensing observations

Current research and/or projects

Develop ground-based integrated observing systems in the Arctic using new remote sensing technologies (radar, lidar, etc.) for meteorological measurements. Investigate applications and capabilities of these new instruments and provide recommendations on technology adoptation. Evaluate their impact on numerical weather prediction models.

  • PI for meteorological research sites in Iqaluit, NU & Whitehorse, YT as part of the Canadian Arctic Weather Science (CAWS) Project, and Squamish, BC research site
  • Test and evaluate new ground-based remote sensing technologies, such as Doppler lidars and radars, and assess their performance and applications in the Arctic climate
  • Produce integrated meteorological products in near-real time, delivered to operational forecasters and researchers, in order to assess their impact on forecast capabilities
  • Provide reccomendations on technology transfer to operations
  • Use the enhanced meteorological observations to evaluate the Canadian numerical weather prediction forecast models
  • Investigate lake breezes, turbulence, and high-impact weather using remote sensing technologies in urban areas and around lake boundaries
