Rossana Dragani

Senior Scientist
Research Department, Earth System Predictability Section, Atmospheric Composition


Rossana is a senior scientist in the Earth System Predictability section (Research Department) where she leads the Atmospheric Composition team. She joined ECMWF after completing her PhD in April 2006. During her time at ECMWF, she has worked on many aspects related to the ozone analysis, spanning data monitoring and assimilation, and model verification, as well as reanalysis. Rossana is  Principal Investigator of international projects, within which she coordinates the ECMWF contributions, and ECMWF point of contact for the SPARC - Reanalysis Inter-comparison Project (S-RIP). Thanks to more than a decade of collaborative research in the field of Earth Observations, she has established very good collaborations with major Space Agencies, in particular with ESA and EUMETSAT.
