Determination of Air Density, Temperature and Winds at High Altitudes,
Abstract
The relationship between the geomagnetic storms observed at the earth's surface and the changes in the density of the atmosphere above 200 km which occur during the storms are reported. Results are presented of analyses of raw satellite data, and of data published elsewhere by Jacchia and SSSlowey. These results show that a linear relationship can be inferred between the changes in density, referred to the undisturbed density, and the geomagnetic index. Detection of acoustic pulses propagated through the earth's atmosphere is performed for temperature and wind structure measurements. A theoretical model of the initial positive overpressure is compaared to 355 and 400 g grenades detonated above Kronogard, Sweden and Woomera, South Australia and recorded at ground level by a UCL multiplex system. Results of these first trials of new equipment are compared to the original direct recording method.
