Nearly complete mosaics of winter ice surface velocities for the 1990's over the Eastern Arctic (Novaya Zemlya, Franz-Josef-Land, Severnaya Zemlya and Svalbard) were compiled based on historical SAR data. Offset-tracking to JERS-1 SAR data of the time period 1992-1998 was mainly applied. Data gaps were complemented using SAR interferometry and offset-tracking of ERS-1/2 SAR data of the time period 1991-1997. Knowledge on ice surface velocity of glaciers and ice caps contributes to a better understanding of a wide range of processes related to glacier dynamics, mass change and response to climate. In order to study long-term variability of winter ice surface velocity from the 1990's to present, velocity maps computed with offset-tracking from 2008-2011 ALOS-1 PALSAR-1 and 2020-2021 Sentinel-1 data are also provided.
