Probing fault frictional properties during afterslip up- and downdip of the 2017 Mw 7.3 Sarpol-e Zahab earthquake with space geodesy

This zip file contains measurements of postseismic surface deformation due to the 2017 Mw 7.3 Sarpol-e Zahab earthquake derived from Sentinel-1 SAR data over a time period of one year after the mainshock. The line-of-sight (LOS) displacements of each satellite track are provided in high-resolution NetCDF file format.

# data format: NetCDF grid file

dlos_yyyymmdd.grd  ---- cumulative LOS displacement since the first postseismic acquisition of each track (unit: meters);  
dates.dat  ----- dates of the SAR image acquisitions of each track (ASCII file)
look_e/n/u.grd --- East, North, Vertical (Up) components of the line-of-sight direction, so that
  
      dlos_displacement = dUe*look_e + dUn*look_n + dUup*look_u

where dUe, dUn, and dUup represent the Eastward, Northward, and Upward surface motion.
