Johannes Orphal

Johannes Orphal (born 11 July 1966, in Magdeburg) is a German physicist. He is Full Professor of Physics and Director of the Institute for Meteorology and Climate Research (IMK) at the Karlsruhe Institute of Technology (KIT). Until 2009 he was Professor at the University of Paris-Est in Créteil and research scientist at the CNRS.

His main scientific contributions are in the field of molecular spectroscopy applied to the Earth's atmosphere: laboratory measurements of unstable and reactive molecules and radicals, data evaluation for international databases e.g. HITRAN, preparation and use of remote-sensing satellite missions (GOME, SCIAMACHY, MIPAS, MetOp, MTG ...) to observe stratospheric chemistry, tropospheric air quality and processes of relevance for climate, as well as the development of sensitive in-situ measurements techniques like IBBCEAS.
