Research Scientist

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

Current research and/or projects

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

  • PI for meteorological research supersite in Iqaluit, NU as part of the Canadian Arctic Weather Science (CAWS) Project and Squamish, BC research site
  • PI for the Southern Ontario Lidar Mesonet to aid high-impact weather forecasting using lidar observations
  • Sub-orbital working group member for the upcoming NASA/CSA AOS-HAWC satellite mission
  • Test and evaluate new ground-based remote sensing technologies, such as Doppler lidars and radars, and assess their performance and applications in the Arctic and urban environments
  • 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 numerical weather prediction forecast models and perform satellite calibration/validation
