ai The fan sector maps of echo power (in dB) taken from 1054 LT (0336 UT) to 1142 LT (0424 UT) showing the onset and growth of F-region irregularities. The horizontal and vertical axes in each plot represent the zonal and meridional distance from the radar site on the Earth’s surface, respectively. The horizontal dashed lines in each plot show the altitudes (from 100 to 500 km with an altitude interval of 100 km) where the radar line of sight is perpendicular to the geomagnetic field. The zonal width of each beam indicates the half power beam width
