A simple boundary condition regularization strategy for image velocimetry-based pressure field reconstruction
We propose a simple boundary condition regularization strategy to reduce error propagation in pressure field reconstruction from corrupted image velocimetry data. The core idea is to replace the canonical Neum...

Surface velocity estimations of ice shelves in the northern Antarctic Peninsula derived from MODIS data
The ice shelves in the northern Antarctic Peninsula are highly sensitive to variations of temperature and have therefore served as indicators of global warming. In this study, we estimate the velocities of the...
