thermosphere
Abstract. The 16-day planetary wave in the polar meso-sphere and lower thermosphere has been investigated using meteor radars at Esrange (68 ◦ N, 21 ◦ E) in the Arctic and Rothera (68 ◦ S, 68 ◦ W) in the Antarctic. The measurements span the 10-year interval from October 1999 to July 2009 and the 5-y...
