A comparison has been made of the properties of the high latitude wind system deduced from rocket vapor trail and Ogo 6 satellite density and temperature measurements. The atomic oxygen densities at high magnetic latitudes are investigated as a function of geomagnetic local time at three seasons for three ranges of magnetic activity. It is shown that the densities at altitudes in the region of 120 km are about 35% lower in the post midnight sector than the afternoon and evening sectors, decrease with increasing magnetic activity, and are lower in summer than in winter. The variations are related to vertical velocities in the 95 km to 150 km altitude region and to the meridional fluxes at 70¿ geomagnetic latitude. It is shown that the poleward fluxes are well correlated with the derived oxygen densities at 120 km. The upward average vertical velocity of atomic oxygen in the region poleward of 70¿ geomagnetic latitude is calculated to be of the order of 0.3 m/s at 120 km and the energy transported by the winds out of this region is calculated to be of the order of 1010 W for Kp levels of 2. The corresponding upward flux of molecular oxygen over the polar caps at 120 km is estimated to be of the order of 3¿1029/s which is comparable with the global fluxes required to balance dissociation above this altitude.
