Description
A method is presented, in which the Pepsios is used to measure
abundances of atomic sodium present in the upper atmosphere
as calculated from the twilight glow. These abundances are
compared with daylight absorption abundances, also measured
using the Pepsios. Ten measurements taken during March,
1971 show an average twilight abundance of (6.1 +- 1.8) x 10^9
atoms/cm^2. This compares with an average absorption
abundance of (3.3 +- 1.1) x 10^9 atoms/cm^2. These limited
data and their attendant uncertainties reveal no significant
discrepancy between twilight and daytime sodium abundances.
