This lecture presents projects I led that use satellites to study the physical processes of Earth's climate, and my main contributions to science in developing remote observations of the cryosphere, with particular emphasis on the quantitative techniques of radar interferometry and radar altimetry. It will discuss studies of arid land degradation using satellite infrared radiometry and models of atmospheric radiative transfer, and my involvement with satellite validation campaigns in Europe, Africa, and Antarctica.
I am Professor of Earth Observation at the University of Leeds, Director of the NERC Centre for Polar Observation and Modelling, Principal Scientific Advisor to the European Space Agency CryoSat satellite mission, and co-leader of the ESA-NASA Ice Sheet Mass Balance Inter-comparison Exercise. I was educated in the Department of Physics and Astronomy at the University of Leicester, and I have held academic posts at University College London, at the University of Cambridge, and at the University of Edinburgh. I am the recipient of: Philip Leverhulme Prize 2008 and Royal Society Woldfson Research Merit Award 2004.
