Raw Co-seismic Deformation Grids for the 2025 Tingri Earthquake (Sentinel-1A & ALOS-2 SAR Interferometry)

This dataset contains the raw grid (*.grd) files used to quantify co-seismic surface deformation associated with the 7 January 2025 Tingri earthquake. The grids are generated from differential SAR interferograms derived from three Sentinel-1A tracks and one ALOS-2 track. ## Included files *_Disp.grd : Line-of-sight (LOS) displacement grid. Positive values point from the ground toward the satellite. (Unit meter) *_E.grd, *_N.grd, *_U.grd : East, North, and Up components of the LOS unit-direction vector at each grid node. These vectors allow reprojection of the LOS displacement into any desired geographic or Cartesian frame. A12_* : Sentinel-1A Track 12 (ascending) D48_* : Sentinel-1A Track 48 (descending) D121_* :Sentinel-1A Track 121 (descending) ALOS2_* :ALOS-2 single track (descending) All grids share the same spatial resolution and geographic extent; the projection and grid spacing are encoded in each file header.
