Xiaolan L. Wang

Research Scientist - Leader, Data Theme, Climate Data and Analysis Section

CURRENT S&T / RESEARCH - 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 contribute to Environment Canada’s mandate on improving knowledge and information on weather and environmental conditions influences decision-making

  • 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
  • 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)


Member of the GCOS/WCRP AOPC/OOPC working group on surface pressure (AOPC-Atmospheric Observation Panel for Climate). Committee member of the "Intercomparison of mid latitudinal storm diagnostics (IMILAST)" international project;

Co-supervisor of the thesis of a Ph.D. student via Adjunct Professorship with the Department of Mathematics and Statsitics, York University; supervisor of a visiting postdoctoral fellow
