Polar cap observations of mesospheric and lower thermospheric 4-hour waves in temperature
1] Lower thermospheric and upper mesospheric rotational temperatures have been derived from ground-based measurements of the O-2(0-1) and OH(6-2) nightglow emissions over Resolute Bay, Canada ( 74.68degreesN, 94.90degreesW) and OH(4-2) nightglow emission over Kiruna, Sweden (67.90degreesN, 21.10degr...
