57-Year Ice Velocity Dynamics in Byrd Glacier Based on Multisource Remote Sensing Data

Long time-series glacier ice velocity reflects the local climate changes and can be used to estimate mass balance (MB) changes, which is a critical parameter for understanding of glacier–climate interactions and prediction of sea level rise. However, due to the difficulty in image matchin...
