- Graduate Position
The Department of Geography and the Cryosphere Climate Research Group at the University of Calgary invite applications for a PhD position in microwave remote sensing of snow covered Arctic first-year sea ice. This four-year position will be located at the University of Calgary in Calgary, Alberta, Canada.
Application deadline: 31 October 2017.
The focus of the research to be undertaken will be the development and application of space-borne and/or surface-based multi-frequency, multi-resolution microwave (Synthetic Aperature Radar and scatterometer) remote sensing datasets for improved characterization of Arctic snow covered first-year sea ice thermophysical processes over the annual cycle. Emphasis is placed on enhancing the existing capacity of space-borne multi-frequency, multi-resolution polarimetric microwave scatterometry for determining critical timings associated with the thermodynamic evolution of sea ice during the spring-summer seasonal cycle and determining regional scale variations of the thermodynamic and geophysical processes operating at the air-ocean interface. Special emphasis on determining/validating the snow water equivalent (SWE) on first-year sea ice will be of particular importance.
The objectives for this Ph.D. studentship will be focused around the development of a robust methodology for estimating snow thickness distributions on first-year sea ice (FYI) from time series surface-based polarimetric scatterometer data and provide “up- scaled” estimates using polarimetric space-borne Synthetic Aperature Radar (SAR) data (ie. RADARSAT-2, Sentinel-1A, Cosmo SkyMed, ALOS PALSAR). The successful candidate will also focus on developing a set of methodologies to infer the surface optical/radiative (albedo) properties of sea ice throughout the spring melt season from time series polarimetric microwave scattering. Opportunities for field work in the Canadian Arctic or sub-Arctic are likely in 2019 and/or 2020.
A Master’s degree in electrical engineering, geography, geomatics engineering, Earth or environmental science, geophysics, or related discipline; a grade point average (GPA) of at least 3.5 on a four-point scale, or equivalent, in the previous two years of study; experience undertaking field research and an interest in working in the Arctic; and technical aptitude are required for this positon. Demonstrable experience working with and handling space-borne optical/SAR satellite datasets with specialization in Polarimetric SAR and previous knowledge in using SAR datasets for sea ice applications are advantageous. Demonstrated experience in producing peer-reviewed publications and programming experience in R, Python, IDL, or MATLAB will be an asset.
Applications must include a letter of interest, a curriculum vitae, transcripts, and contact information for three references.
