Ingeborg Levin was awarded Venia Legendi for Physics, and approval as Privatdozentin in August 1994. In 2005, she was approved as Außerplanmäßige Professorin by the Ruprecht-Karls-Universität Heidelberg. Ingeborg Levin's main research interests are the study of the biogeochemical cycles of long-lived greenhouse gases and their recent and past changes using isotope tracer measurements and global and regional modelling.
Professor Marina Lévy, LOCEAN-IPSL, CNRS, France Sources, sinks, and distribution of sea-surface pCO2: role and magnitude of sub-mesoscale processes
After graduating from Ecole Polytechnique, Marina Lévy prepared her PhD thesis on the oceanic carbon cycle in the Mediterranean Sea at the University of Paris 6. In 1998, she worked under a post-doctoral fellow-ship at the Lamont-Doherty Earth Observatory of Columbia University, and obtained, in 1999, a permanent position at CNRS. She was awarded the CNRS bronze medal in 2004 for her pioneering work on the interactions between sub-mesoscale physics and phytoplankton productivity. Her approach combines numerical modelling, satellite data and field observations. She is now head of the Bio-Physical Interactions group at the Oceanography and Climatology Laboratory LOCEAN in Paris. She is PI of the project TANGGO (Toward AN eddying Global Green Ocean) which aims at improving the predictability of primary production, and involves over 25 institutes. She is a regular visiting scientist of the Earth Simulator Center, in Yokohama, Japan and of the National Institute of Oceanography in Goa, India.
Professor David MacKay FRS, University of CambridgeThe scale of the decarbonization challenge
David MacKay FRS is a Professor in the Department of Physics at the University of Cambridge. He studied Natural Sciences at Cambridge and then obtained his PhD in Computation and Neural Systems at the California Institute of Technology. He returned to Cambridge as a Royal Society research fellow at Darwin College. He is internationally known for his research in machine learning, information theory, and communication systems. He has taught Physics in Cambridge since 1995. He is author of the critically acclaimed book, "Sustainable Energy - without the hot air".
Dr Alistair Manning, Met Office, UKThe challenge of estimating regional emissions from observations
Professor Martin Manning, Victoria University of Wellington, New ZealandThe growing priority for understanding greenhouse gases in a policy perspective
Professor Justus Notholt, University of Bremen, GermanyGround-based total column measurements of greenhouse gases using the solar absorption spectrometry
Prof. Dr. Justus Notholt graduated in Solid State Physics at the University of Kassel in 1985. In his diploma thesis he studied the structure of amorphous semiconductors using X-ray spectroscopy. He received his PhD degree in Physical Chemistry at the same University in 1989 in the field of Surface Enhanced Raman Scattering, working in the area surface science and electrochemistry. As a postdoctoral fellow at the Joint Research Centre of the EC in Ispra/Italy, he switched to atmospheric science where he advanced a DOAS-system for simultaneous measurements of atmospheric trace gas and aerosol concentrations. In September 1990, he moved to the Alfred-Wegener-Institute for Polar and Marine Research. There he began atmospheric trace gas observations in both Polar Regions and developed measurement and analysis techniques for using the moon as infrared light source during the polar night. Furthermore he started ship borne FTIR measurements to obtain the latitudinal variability of atmospheric trace gases. In April 2002 he obtained a professorship at the University of Bremen. His activities now comprise development and application of spectroscopic observations from the microwave via the infrared to the visible spectral region, using ground-based and satellite instruments. Scientific topics are greenhouse gas observations, stratospheric and mesospheric studies, and sea-ice remote sensing.
Dr Peter Rayner, Laboratoire des Sciences du Climat et de l'Environnement, FranceReducing uncertainties in future terrestrial carbon sinks: an approach using process models and data assimilation
Peter Rayner studied theoretical physics at the University of Melbourne. He obtained his doctorate from the same university in 1991 for his studies on glacial-interglacial cycles. In 1989 he was awarded a CSIRO Postdoctoral Fellowship at the Division of Atmospheric Research (DAR) which included a one year stint at the National Center for Atmospheric Research in Colorado. In 1991, Peter joined the Program in Atmospheric and Oceanic Sciences at Princeton University where he began his research on the global carbon cycle.

Professor Ray Weiss, Scripps Institution of Oceanography, University of California, San Diego, USAQuantifying greenhouse gas emissions from atmospheric measurements: a critical reality check for climate legislation
Ray Weiss is a Distinguished Professor of Geochemistry and Associate Dean at the Scripps Institution of Oceanography, University of California, San Diego. He holds a BS in chemistry from the California Institute of Technology and a PhD in earth sciences from Scripps. His career has been devoted to the use of chemical and isotopic measurements to study natural processes in the oceans, lakes and the atmosphere. Among his principal research accomplishments are: the first experimental proof of the existence of deep-sea hydrothermal vents; using dissolved atmospheric chlorofluorocarbons to determine the rates of ventilation, transport and mixing processes in the deep ocean and in deep lakes; discovery of the global rates of increase and distributions of atmospheric nitrous oxide and other greenhouse gases; and calibrating the global abundance of the atmospheric hydroxyl radical, the atmosphere's primary cleansing agent. Professor Weiss is a Fellow of the American Association for the Advancement of Science, and of the American Geophysical Union. He leads the measurement component of the Advanced Global Atmospheric Gases Experiment (AGAGE), an international program to trace and model the emissions, global distributions and atmospheric lifetimes of a wide range of anthropogenic and natural greenhouse gases and ozone depleting substances.
