Title: A spatiotemporal model for arctic sea ice trajectories
Authors: Yawen Guan - Colorado State University (United States) [presenting]
Abstract: Arctic sea ice is a barrier between the warm air of the ocean and the colder atmosphere. Thus, it plays an important role in the climate. When narrow linear cracks (leads) form in the sea ice, the heat from the ocean is released into the atmosphere. Motion data from the RADARSAT geophysical processing system (RGPS) is analyzed to estimate where leads may form. RGPS provides a set of trajectories of points on an ice sheet to trace the displacement of sea ice; however, chunks of data are missing because data is collected by satellite. A spatiotemporal clustering and interpolation method is proposed that estimates where a lead may form and allows the inference of missing observations.
