Among other the data exhibit E-W shortening in the fold-thrust-belt, slip activity of the Babadag thrust fault and the Ilyak strike-slip fault, westward Pamir escape tectonics, halokinesis and near-surface, water-driven effects. Observations and methodology are discussed at length in Metzger et al., 2021 (under Review).
Pre-processed interferograms of 13 Sentinel-1 radar frames serve as the input data for a framewise small-baseline time-series analysis using the LiCSAR/LiCSBAS data processing chain (Lazecky et al., 2020, Morishita et al., 2020). The resulting rate maps in line-of-sight were first tied to the Eurasian-fixed reference frame spanned by available regional GNSS data. If data from two view directions were available, they were decomposed in east and up by fixing the north rates to the interpolated GNSS north rates (Ou, 2020).
The zip-folder contains 1) the framewise rates and uncertainties and corresponding line-of-sight (LOS) information, all labelled by frame numbers, 2) the interpolated north rates based on Eurasian-fixed GNSS and 3) the concatenated and decomposed east and up rates in a Eurasian-fixed reference frame. A GMT script (Wessel & Smith, 2013, v6.0.0) and corresponding Figures serve as an example on how to plot the data.
