Biography

Andrew Shepherd uses satellites to study physical processes of Earth's climate. He is a member of the NERC National Centre for Earth Observation, coordinator of the European Space Agency VECTRA InSAR consortium, and a contributing author of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. Andrew's main contributions to science have involved remote observations of the cryosphere, with particular emphasis on the quantitative techniques of radar interferometry and radar altimetry. He has also worked on studies of arid land degradation using satellite infrared radiometry and models of atmospheric radiative transfer, and he has led satellite validation campaigns in Europe, Africa, and Antarctica. His currently funded research includes investigations of the stability of the Larsen Ice Shelf in Antarctica, developing methods to retrieve elevation in regions of rugged terrain using the CryoSat-2 interferometric altimeter, estimates of the sea level contribution due to Antarctica and Greenland, and monitoring changes in Earth's glaciers and ice caps.
