This data set contains the neutral densities measured by the Neutral
Density and Temperature Probe (PI: N. Spencer) during the AEROS-A
satellite mission. The data are in ASCII format and cover the time period
from 12/26/1972 to 8/9/1973. The four different files provided in this
data set contain the data for He, O2, N2, and Ar, respectively. Each data
record provides date, time, density, density error, altitude, latitude and
longitude, and local solar time.
