Dr. Andrea Storto is an environmental engineer and has obtained his Ph.D. in 2009 at the University of Rome La Sapienza in close collaboration with the Norwegian Meteorological Institute (met.no), studying the optimal assimilation of satellite radiances for regional medium-range NWP models by using variational assimilation schemes. He had got a research fellowship from EUMETSAT and, further to met.no, he has been also visiting Meteo-France/CNRM, JAMSTEC, Mercator Océan and ECMWF. In 2009, he joined the Ocean Modeling and Data Applications (ODA) Division of CMCC to develop a Global Ocean variational analysis system at eddy-permitting resolution for use in the context of ocean reanalyses, in particular within the EU-funded MyOcean project and its follow-ups MyOcean2 and CMEMS. He significantly contributed to the development of high-resolution operational forecasting systems in the global ocean, the Black Sea and the Mediterranean Sea. His expertise mainly includes variational data assimilation, satellite altimetry, techniques for improving the representation of model errors in data assimilation and evaluation of ocean reanalyses. He coordinated the group on ocean data assimilation and forecasting at CMCC/ODA. In 2018 he joined the CMRE as research scientist to work on regional oceanographic and acoustic data assimilation. He is co-chair of the CLIVAR panel on global observations and ocean syntheses (GSOP), and member of the GODAE Task Team on data assimilation. He was P.I. of the CMEMS SOSSTA project for the optimal formulation of sea surface temperature data assimilation, and he coauthors more than 70 scientific publications.
