Forwarded from CLIMLIST... PhD position in ice sheet elevation and elevation change from radar altimetry observations at the School of GeoSciences, Edinburgh, UK The candidate will work on radar altimetry measurements over the Greenland and Antarctic Ice Sheets. The position is funded through the European Space Agency project CryoTop Evolution (Space-borne observations for mapping fine elevation and elevation change over Ice Sheets). The thesis will consist in processing and analysing CryoSat-2 radar altimeter datasets with the objectives of improving the spatial and temporal resolution of elevation and time varying elevation to better quantify changes affecting the Greenland and Antarctic ice sheets. The working environment at Edinburgh (<http://www.geos.ed.ac.uk/glaciology>) and within the project’s consortium provides excellent opportunities for learning and collaboration in the fields of remote sensing, field observations, and numerical modeling of polar research. Tasks: Climate warming over the 20th century has caused drastic changes in the Greenland and Antarctic Ice Sheets (GrIS, AIS) which in turns is impacting rates of sea level change. Observation from Satellite altimetry is a powerful approach to quantify changes in the Ice Sheet mass and to investigate the processes that link the Cryosphere, Atmosphere and the Ocean. Reference and repeat-observations of Ice Sheet topography is critical to quantify changes in ice thickness, provide estimates of ice mass change and contribution of the cryosphere to sea level change. Retrieving ice elevation present significant challenges as many regions require very fine spatial resolution. An estimated of ~50 & ~75 % of Antarctic and Greenland ice sheet mass losses are within 100 km of coast, but <10 % of these regions are surveyed by conventional altimetry because of sparse ground tracks and coarse resolution footprints failing due to high slopes. Radar altimetry mission CryoSat provides a step change in our ability to map the coastal region of the GrIS and AIS thanks to its tighter ground track distribution and its SAR interferometry mode enabling high-resolution elevation mapping. The following work is envisaged: • Analyses of CryoSat-2 dataset to generate surface elevation and elevation change over the GrIS and AIS. • Propose and implement strategies to enhance the above products. • Analyse the findings and contribution to sea level change Requirements: You must have a degree in geophysics, meteorology, physics, or comparable science. Experience in scientific programming, analysis of remote sensing, and good English skills (spoken and written) are expected. Basic knowledge of polar processes (land ice, ocean, atmosphere) is of advantage. Application deadline is 22 April 2016.
