Research Scientist - Data Assimilation and Satellite Meteorology
CURRENT S&T / RESEARCH - Contributing to Environment Canada mandate to improve numerical weather prediction through the assimilation of observations, in particular active remote sensing data
- Impact studies of the various meteorological observing system on numerical weather predictions
- Assessment of the role of the conventional observing network to provide objective guidance for rationalization purposes and for a better use of these sources of data, over North America in particular
- Examination of the value of satellite observations over the Pacific Ocean and their role in the short to medium range weather forecasts over Canada and the United States
PROFESSIONAL ACTIVITIES / INTERESTS
Lead of the active remote sensing group within the Data Assimilation and Satellite Meteorology section. These types of observations include GPSRO, GPSGB, wind profiler, scatterometers, SAR, radial wind and reflectivity from Doppler radar and spaceborne wind lidar
Member of the users and science team for the RADARSAT-Constellation mission proposed by the Canadian Space Agency
