Deformation, Strains and Velocities for the Alpine Himalayan Belt from trans-continental Sentinel-1 InSAR & GNSS

This dataset provides velocity and strain rate fields for the Alpine-Himalayan Belt (AHB) derived from Sentinel-1 InSAR, GNSS, and levelling data. Details are provided in Elliott et al. (2026). The directory overview for this dataset is given below: ENU_vels/East-west, north-south, and vertical velocity fields, along with their associated uncertainties. georeferenced_los_vels/Line-of-sight (LOS) velocities in a Eurasia-fixed reference frame defined by GNSS GNSS_levelling_data/Compiled GNSS velocities and levelling rates from published studies. LiCSBAS_los_vels/Original LOS velocities, uncertainties, and corrections derived from LiCSAR/LiCSBAS processing. strain_rates/Components of the second invariant, maximum shear, dilatation, and vorticity. velmap_strain_rates/Strain rates calculated from velmap. velmap_vels/Coarse 3D velocity models derived from velmap. The InSAR line-of-sight displacement time series dataset is available at CEDA Archive. Original-resolution figures have been provided in a separate zip file. Strain rates derived using different filtering window sizes can be added to this repository upon request ([e-mail]).
