    Description: The satellite eclipse technique of ozone measurement is evaluated to determine its accuracy and resolution. The method of obtaining ozone concentrations from ground-based observations of eclipsing satellites is described, the theory of this method is outlined, and the data reduction procedure is summarized. It is shown that the satellite eclipse technique successfully measures the vertical distribution of ozone from 15 to 40 km with precisions ranging from + or - 12% between 20 and 35 km and + or - 25% at both 15 and 40 km. The ozone profile is found to be in good agreement with in situ measurements obtained from an ozonesonde launched near the eclipse tangent point at local sunset, the percent differences being less than 14% from 20 to 40 km.

    Description: A systematic asymmetry in the neutral exosphere between the Northern and Southern Hemispheres has been identified for the first time after correcting for all other known systematic variations. This phenomenon was clearly detected from recent measurements of helium drag effects near 1000 km on the low mass-to-area ratio Explorer 19 satellite. From a reanalysis of all four NASA Langley Air Density Explorer satellites (Explorers 9, 19, 24, and 39), this systematic asymmetry was traced over an entire solar activity cycle. It was found that helium concentrations in local summer at high latitudes are generally more than 50% lower in the Southern Hemisphere than in the Northern Hemisphere. In addition, the increase in helium concentrations from summer to winter was found to be approximately 80% greater in the Southern Hemisphere than in the Northern Hemisphere.
