Paul received the MPhys Physics degree from the University of Manchester, UK, in 1998 and the PhD degree in atmospheric physics from Imperial College London in 2003. Between 2003 and 2011, he took up a position of postdoctoral research associate at Imperial College London, where his research focused on infra-red spectroscopy of the atmosphere, water vapour and ice clouds to better understand the processes that control the energy budget of the Earth's atmosphere. In 2011, he joined (the then) Earth Observation, Climate & Optical group at NPL, since promoted to his current position as Principal Research Scientist and group Science Area Leader.
Paul is a Chartered Physicist, Fellow of the Royal Meteorological Society and a Member of the Institute of Physics, having served in a number of posts on the Institute of Physics Environmental Physics Group committee between 2012 and 2020.
Dr Paul Green is the Science Area Leader in the Earth Observation & Climate group. Paul's research interests are in the optimisation of Earth Observation dataset quality, through the development of pre-flight and on-orbit calibration and characterisation facilities and techniques for EO sensors, spanning from the UV-VIS-NIR into the IR and microwave spectral domains, together with the validation of EO datasets through comparison with other satellite sensors and ground-based and airborne reference sensors, and the techniques needed to make meaningful comparisons.
Paul is a senior member of the NPL TRUTHS team, an ESA EarthWatch mission designed to provide a SI-traceable high accuracy satellite record of the state of our climate and a on-orbit satellite cross-calibration reference. Paul leads the NPL contribution to the industrial consortium, led by Airbus UK.
Paul leads the atmospheric domain within the Earth Observation & Climate group, working on species of air quality and climate significance, with a focus on satellite-derived greenhouse gases products, their uncertainties and provenance.
