Current research and/or projects
Climate trend/extremes/variability analysis, and development of methodologies for more realistic assessment and better understanding of climate trend/extremes/variability, to provide international leadership in this area of research, and to provide critical information to support the Department’s mandate within my areas of expertise
- Development of techniques for climate data homogenization, to enable more realistic assessment of climate trend, extremes, and variability;
- Homogenization of climate data (surface winds, surface pressure, precipitation, ocean wave heights…)
- Development of methodologies for analyzing climate trend, extremes, and variability (including methods for projecting possible future climate extremes)
- Analysis of observed climate trend, extremes, and variability, including ocean surface waves
- Projections of future changes in various aspects of the climate system (including climate extremes) by analyzing (and statistical downscaling) climate model projections
- Development of methodologies for blending in-situ gauge precipitation data with satellite precipitation estimates, and production of a blended gridded precipitation database for Canada (North America)
