This microfiche data set, of atmospheric density values computed from the atmospheric drag on AE-B (Explorer 32), 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, Mass., 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. The data appear in both tables and graphs. The graphs are all plotted against modified Julian day as abscissa and show, in order, log of atmospheric density reduced to 300 km, diurnal variation, semi-annual variation, solar 10.7-cm flux values, and the Ap geomagnetic field index. Included in the tabular data are values for common logs of atmospheric density at perigee height and at a reference height, and the perigee height. The local exospheric temperature values, taken from the Jacchia '71 Model, that correspond to the measured densities are shown also.
