Horizontal range of GPS tomography in this study. The latitude range is from 6°N to 70°N and the longitude is from 100°E to 165°E. The horizontal resolutions are 1° within the blue area (30°N–40°N in latitude and 130°N–140°N in longitude), 2° within the black area (6°N–54°N in latitude and 120°N–154°N in longitude), and 5° outside the black area, respectively. Red point indicates the location of ground-based GPS receiver
