Abstract
The Ca layer abundance varied between 2.1-10.7 × 107 cm-2, with an average of 6.3 × 107 cm-2. The Na abundance averaged 7.2 × 109 cm-2, or approximately 110 times that of Ca. The Ca layer centroid height varied between 90.8 and 92.5 km, with an average value of 91.8 km, and was on average 0.2 km higher than the Na layer centroid height. The rms widths of the Ca and Na layers averaged 3.5 and 4.7 km, respectively. No substantial sporadic Ca or sporadic Na layers were detected during our observations. Considerable gravity wave activity was observed in the Ca, Na, and temperature profiles on December 21-22, 1992. -from Authors
