| Abstract: | Using coordinated observations from the Cluster,DMSP and ESR radar,high-altitude cusp was investigated for a time period characterized by four fast reversals of the IMF BZ.On February 12,2003,Cluster was flying sunward at duskside over the Northern Hemisphere,across the high-altitude northern cusp twice.Both the two crossings are during steady northward IMF interval,whereas ion fluxes detected during the time period are quite different.The cusp in the first crossing is a typical northward-IMF one,with short... |
