Spatial distribution of the time difference between the onset times of TEC perturbation in the ionosphere and temperature deviation in the troposphere. The horizontal and vertical axes indicate the geographic longitude and latitude in degrees, respectively. The color scale indicates the time difference ranging from 0 to 120 min. The red dotted curve is the magnetic equator. The concentric circles represent a distance from the Tonga volcano every 1000 km.
