TLDR
In this article, regular measurements of the sodium layer at 90 km height, during twilight and throughout the night, by means of a laser radar are reported, and the main features observed are night-time abundances similar to those at twilight, topside scale heights of 2-3 km and fluctuations corresponding to patches of sodium extending over horizontal distances of 10-200 km.About:

The chemistry of meteoric metals in the Earth's upper atmosphere
TL;DR: The presence of thin layers of free metal atoms at around 90 km in the upper atmosphere has been known for about fifty years as mentioned in this paper, and several techniques have been developed to observe the metal layers, including ground-, rocket-and space-based photometers, and in particular metal lidars.

TL;DR: In this paper, sudden sodium layers (SSLs) are observed with a lidar instrument at Andenes, Norway (69°N) and their appearance shows a strong, positive correlation with that of ƒ-type Es layers.

The seasonal variation of the night-time sodium layer
A.J. Gibson,M.C.W. Sandford +1 more
TL;DR: The height distribution of sodium has been measured on 60 nights between July 1969 and July 1970 by observations of the resonance scattering of a tuned laser beam, and the seasonal variation in abundance shows a maximum during winter and a minimum in summer in agreement with the twilight glow from the layer.

Photochemistry of ozone in a moist atmosphere
TL;DR: In this article, a detailed investigation has been made into the photochemistry of ozone in an atmosphere containing hydrogen, and it is shown that for such an atmosphere a satisfactory ozone profile can be obtained, unlike the situation now existing for an oxygen only atmosphere.

Rocket measurements of the sodium dayglow
D. M. Hunten,L. Wallace +1 more
TL;DR: Sodium dayglow photometers were flown on Aerobee rockets on the mornings of April 7 and June 19, 1964 as discussed by the authors, and good profiles of the emission were obtained for comparison with twilight measurements.
