Table 2. Vertical change measured using interferometric synthetic aperture radar (InSAR) for 3 areas in the Coachella Valley, California, 2003–2005.
[Negative values for magnitude indicate subsidence. Bold type indicates conservative value owing to increased incoherency associated with longer timelines. Shading: Green shade indicates that the interferogram is shown in figure 6A; brown shade indicates that the interferogram is shown in figure 7A; and pink shade indicates that the interferogram is shown in figure 8A. ft, foot; i, incoherent; mm, millimeter]
