Ralph Keeling

Ralph’s work centers on long-term measurements of the majorRalph Keeling constituents in air.  He has been on the faculty at the Scripps Institution of Oceanography, UC San Diego, since 1993.  He was the first to demonstrate that the O2 content of air is decreasing due to the burning of fossil-fuels and has directed a program to track this decrease since 1989.  Since 2005 he has also directed the Scripps CO2 program which sustains the iconic record of carbon dioxide at Mauna Loa and other sites, begun by his father, Charles D. Keeling. He is engaged in ongoing research to refine estimates of sources and sinks of carbon dioxide using atmospheric measurements. Keeling has received the Rosenstiel Award in marine and atmospheric chemistry, the Humboldt Research Award, and is a Union Fellow of the American Geophysical Union.

His thesis work focused on the characterisation and optimisation of the new Imaging Fourier Transform Spectrometer GLORIA (Gimballed Limb Observer for Radiance Imaging of the Atmosphere). Dr. Sha is interested in the Earth’s carbon cycle, sources and sinks of greenhouse gases and other climate relevant gases. His research focuses on the characterisation and operation of high- and low- spectral resolution FTIR instruments, making precise and accurate measurements of atmospheric trace gases using in-situ and remote sensing techniques, data retrieval, geophysical data exploitation, and satellite validation. He is a member of several ground-based FTIR networks, namely, TCCON, COCCON, and NDACC. 


Peter LandschutzerLandschutzer

Peter Landschützer received his PhD at the School of Environmental Sciences at the University of East Anglia, where he developed a novel 2-step neural network interpolation technique to estimate the air-sea CO2 exchange from surface ocean pCO2 observations, which he refined during his post-doc at the Swiss Federal Institute of Technology in Switzerland. Currently, he is research group leader of the ’Observations, Analysis and Synthesis’ group at the Max Planck Institute for Meteorology in Hamburg, Germany. His research focuses on the collection of in-situ CO2 measurements and the combination measurements with machine learning techniques to quantify the ocean carbon sink, its uncertainty and its evolution in time.


Thomas LauvauxLauvaux

Thomas Lauvaux currently works at the LSCE in Atmospheric and Carbon Cycle Sciences. He is a PennState University Affiliate. His main research interest is to understand the roles of the biosphere and of various human activities on the carbon cycle using data assimilation techniques. By combining atmospheric greenhouse gas measurements and numerical weather models, he collects information on the exchanges of carbon from land and coastal surfaces to the atmosphere. He is particularly interested in satellite measurements and dense network of ground-based sensors to characterize carbon sources from large metropolitan areas, the impact of oil and gas production activities, and to understand carbon sinks from natural and agricultural landscapes.


Denis LoustauDenis Loustau

Denis Loustau (forest ecophysiology, bioclimatology, forest modelling, carbon cycle, climate change) is senior scientist in INRAE, research unit ISPA (Soil, Plant Atmosphere Interaction) at Bordeaux. He obtained his Ph.D. in 1984 about Plant Ecology and Soil Science at University Henri Poincaré, Nancy, France, and has a Master degree in Ecology from Paris Sorbonne University. He spent sabbatical years as invited scientist in Laval University, Quebec, 1986 and Edinburgh University, UK. He has been coordinator of the Ecosystem national branch of the ICOS European infrastructure since 2009 and coleader of the ICOS Ecosystem Thematic Center until 2017.  Along his career, Denis L. has investigated the water balance and water relations in Pine trees and forest, photosynthesis and carbon metabolism of trees, and he has been developing forest models representing the main biophysical and biogeochemical processes in managed forest ecosystems.
