Research Scientist - Meteorological Data Assimilation
CURRENT S&T / RESEARCH - Contributing to Environment Canada's mandate to improve meteorological forecasts by improving the use of atmospheric observations in the global analysis system.
- Estimation and modelling of background error covariances for global four-dimensional variational data assimilation.
- Research and evaluation of a new data assimilation approach (En-Var: ensemble-variational) for producing deterministic analyses.
- Application of variational data assimilation approaches to the analysis of sea ice conditions.
