MT-InSAR-derived velocity maps of the Tajik Basin and Dushanbe Trough

Velocity maps of the Tajik basin, Dushanbe Trough, and surroundings, resulting from a multi-temporal InSAR analysis of Sentinel-1 data. This is the InSAR data repository for the following manuscript: Wilkinson, R., Daout, S., Walker, R. T., Dodds, N., & Ischuk, A. (2025).
