About me

My main field of research focuses on space-based remote sensing of clouds and aerosols to improve our understanding of the interaction between clouds, aerosols and radiation. A second research direction is related to the retrieval of extreme (hurricane) winds from satellite observations. Our aim is to improve our understanding of the use of C-band VH information on the retrievals of high and extreme winds from future C-band scatterometer missions (i.e. EPS-SG).

Projects

I have been involved as project manager and algorithm developer in the ESA projects (APRIL & ATLAS) where we work on the development of retrieval algorithms for the ATLID (lidar) and MSI (multi-spectral imager) instruments onboard the ESA/JAXA Earth Clouds and Radiation Explorer (EarthCARE) satellite mission. CM SAF (EUMETSAT) generates high-quality climate data records of variables describing the energy and water cycle. Two main data records of cloud properties, as well as, radiation and surface albedo, have recently been produced: CLARA-A2 (global, AVHRR-based, starting in 1982) and CLAAS-2 (Europe/Africa/Atlantic, SEVIRI-based, starting in 2004).
