Activities
My research interests are cloud processes and cloud radiation interaction, remote sensing of cloudy atmosphere. I work mainly on the characterization of 3D cloud structures from satellite,
using multi-angle passive measurements in the oxygen-A absorbing bands, in synergy with active measurements. I am also interested by the complex variability of surface solar irradiance due to clouds.
Methods
- Exploitation of A train measurements
- Retrieval algorithm of cloud parameters from satellite remote sensing
- Radiative transfer: successive order of scattering approach, Monte-Carlo radiative transfer
- Exploitation of pyranometer and pyrheliometer measurements
