Day-side auroral signatures based on simultaneous, coordinatedobservations at Svalbard and Greenland

The height distribution of the dayside cusp aurora and the relation between optical emissions and net downward electron energy flux are discussed. These two important characteristics of day-side cusp aurora are still unknown. It is instructive to compare particle flux and optical luminosity because these two quantities should be proportional if the cusp aurora is caused by electron impact, as has been found for nighttime aurora in the oval. Furthermore, there should then be a direct relation between auroral altitudes and particle energy. Based on coordinated auroral observations at Svalbard and Greenland, together with simultaneous, overhead F-9 satellite measurements, these quantities have been evaluated 相似文献

After a brief biography of K.B. Birkeland, the author describes Birkeland's electromagnetic gun project and provides details of the so-called Gala lecture at the University of Oslo on Feb. 6, 1903, when Birkeland officially demonstrated his gun. The future potential of Birkeland's gun for mass transport and rocket launches is also examined 相似文献
