Three-Dimensional Surface Deformation Field Related to the 2017 North Korea Nuclear Test

Three-dimensional (3D) surface deformation field was retrieved by using the two ALOS PALSAR-2 stripmapinterferometric pairs that acquired from the ascending (20170829_20170912) and descending (20170831_20170928) orbits. For this, the ascending and descending LOS and AT deformations were created from the pairs by the multi-kernel offset tracking method, and then 3D deformation field was retrieved from the ascending and descending LOS and AT deformations. 

For the 3D deformation field, the unit is centimeter and the coordinate system is geodetic with the WGS84 ellipsoid.
