This microfiche data set of atmospheric density values, computed from the atmospheric drag on Explorer 9, was prepared at NSSDC from Smithsonian Astrophysical Observatory Special Reports numbered 100, 171, 326, and 368 (NSSDC TRF B10138, B05917, B10163, and B27448). These density values were computed for standard heights between 270 and 760 km. The data are primarily in tabular form. There are some summary graphs for comparing changes in density as a function of diurnal and semiannual temperature means, 10.7-cm solar flux, and daily geomagnetic index. The tabulated density values are listed chronologically. Some of the other parameters given are the observed rate of change of anomalistic period, the acceleration due to solar radiation pressure, the perigee height, and the nighttime temperature computed from the perigee value using a Jacchia model of diurnal temperature variation.
