Diurnal variation of upper atmospheric parameters determined from U.S. and USSR rocket and satellite observations. Day-to-night variation of temperature and particle densities between 100 and 500 km are presented. The findings are a refinement on prior work, inasmuch as they take into account the varying proportions of constituent gases at upper levels. The resulting curves differ significantly from those of the so-called "standard" atmospheres.
