Description

This zip file contains the InSAR line-of-sight (LOS) displacements derived from Sentinel-1 data collected along four satellite tracks (T42,T64, T137, T144) covering the 2021 M6 Antelope Valley earthquake in Eastern California. For each track, all possible interferograms of roughly 1-month long in time spanning the earthquake without sharing a common scene are stacked to obtain the average coseismic LOS displacement. See text for details.

 

# data format: NetCDF grid file

"dlos_stack_coseismic.grd"  ---- average coseismic LOS displacement (unit: meters); positive value corresponds to surface deformation toward the satellite.

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.

 

We also provide the ascii-format downsampled LOS displacement of each track that went into the coseismic slip modeling ("dlos_stack_coseismic_samp.txt"). The file contains 6 columns:

#longitude  latitude  dLOS(cm) vE    vN  vUp
