Yvan Joseph Orsolini

Dr. Yvan Orsolini joined NILU in March 1998 as a senior researcher posted at Kjeller, Norway. 

He earned his MSc. in Atmospheric Sciences from the University of Illinois (Urbana, USA) and his PhD is in geophysics from the University of Washington (Seattle, USA). He has worked with dynamics, chemistry and remote sensing of the middle atmosphere and, in particular, with the Earth’s ozone layers and the solar radiative and particle impacts on the atmosphere. 

Another area of research is cryosphere-atmosphere interaction, in particular the role of snow and sea ice in the climate system and in seasonal predictions. 

He has a long experience working with general circulation models, either atmosphere-only or coupled ocean-atmosphere models, including whole-atmosphere models (such as WACCM) which extends into the lower thermosphere, as well with seasonal prediction systems. He has also contributed to the analysis of numerous satellite remote sensing datasets (UARS, SABER, ENVISAT, MLS, SOFIE,…), and atmospheric re-analyses regarding dynamics or composition. 

He has coordinated one European project and several Norwegian Research Council projects on behalf of NILU, while participating to numerous other projects. He was affiliated part-time (20%) with University of Bergen (2010-2020) and with NTNU (2020-2023). 

His h-index is 40, with over 5000 citations (Google Scholar).
