Jochen Landgraf is senior scientist at SRON Netherlands Institute for Space Research leading a group for atmospheric trace gas remote sensing. He obtained his PhD at the Max-Planck Institute for Chemistry in Mainz, Germany, where he developed a technique for efficient online calculations for photo-dissociation rates. At SRON his research is focused on remote sensing from satellite measurements, particularly from TROPOMI, Sentinel-5, OCO-2, GOSAT-1 and GOSAT-2 observations. His recent work concerns new remote sensing concepts to retrieve carbon monoxide, carbon dioxide and methane using satellite measurements in the visible and near and shortwave infrared in combination with emission spectra in the thermal infrared. He is member of ESA’s Sentinel-4 and -5 mission advisory group and of ESA’s Sentinel-7 candidate mission for anthropogenic CO2 Monitoring.
