This microfiche data set, of atmospheric density values computed from the atmospheric drag on Explorer 39, was prepared at NSSDC from the report: L. G. Jacchia et al., "Supplemental catalog of atmospheric densities from satellite-drag analysis," Smithsonian Astrophys. Obs., Spec. Rept. 348, Cambridge, MA, Dec. 1972. A single copy of this report is available for use at NSSDC as TRF B15428. On request, individual pages can be copied as required or a microfiche copy can be supplied. These density values were computed for heights between 800 and 850 km. The data are primarily in tabular form, with some summary graphs shown for comparing changes in density as a function of diurnal and semiannual mean temperatures, solar 10.7-cm flux, and the daily geomagnetic index. The tabulated density values are listed chronologically, and include among other parameters the observed rate of change of anomalistic period, the acceleration due to solar radiation pressure, and perigee height.
