Fig. 1From: Latitudinal dependence on the frequency of Pi2 pulsations near the plasmapause using THEMIS satellites and Asian-Oceanian SuperDARN radarsField of view of the Hokkaido, Tiger, and Unwin radars, the footprints of the THEMIS A, D, and E satellites at an altitude of 100 km, and geomagnetic stations at 09:12 UT on August 19, 2010. Shaded regions of the field of view indicate locations of echoes with Pi2 frequencies. Satellite footprints were calculated by using the T96 geomagnetic field modelBack to article page
