Analyse of the stratospheric winds using balloons trajectories and biases estimation of the ERA-Interim reanalysis data
In a current context focused on the ozone layer recovery and on the global warming, understand, represent and model the stratospheric dynamic became major issues. Realism of these models needs to be assessed. Unfortunately the stratosphere is an atmospheric layer hardly accessible to measurements. B...

In a current context focused on the ozone layer recovery and on the global warming, understand, represent and model the stratospheric dynamic became major issues.
