The CryoTop project aims to develop a new production system to deliver routine and repeat measurements of fine glacier and ice sheet margin (GISM) topography, derived from the CryoSat-2 interferometric altimeter. Using this method, a potential 25-75 fold increase in the density of elevation data may be acheieved with an estimated accuracy of 1.3-2.1 m. In order to acheieve this aim, two objectives have been identified.
Develop, assess and select the most suitable algorithm for retrieval of GISM topography based on CryoSat-2 SarIn data.
Validate this method using independent measurements of GISM elevation
Apply this method to selected regions around the globe, and produce new estimates of GISM topography, at high spatial resolution
