Jean-Marc Bélanger

Senior Physical Scientist - Numerical Modelling

Current research and/or projects

Development of a global coupled atmosphere-ice-ocean model for environmental prediction in collaboration with national (DFO, DND) and international (MERCATOR) partners

  • Coupling of global atmospheric and oceanic models in a massively parallel computing framework
  • Sensitivity studies of global atmospheric forecasts to SST perturbations
  • Study of physical processes at the atmosphere-ocean interface
  • Atmospheric data assimilation

Professional activities / interests

Ten years experience in atmospheric data assimilation mostly in the context of R&D in support of the operational 3D/4D variational data assimilation systems at the Canadian Meteorological Centre

Three years experience in processing and assimilation of surface wind measurements over the ocean from satellite data (scatterometer)

Experience in adjoint model coding (computational differentiation) applied to data assimilation

Three years experience in implementation and experimentation with land surface processes parameterization CLASS (Canadian Land Surface Scheme) in the multiscale atmospheric model (GEM)
