Abstract

During conditions of northward interplanetary magnetic field (IMF), the near tail plasma sheet is known to become denser and cooler. The mechanisms, and their efficiency, which allow for the formation of this cold dense plasma sheet (CDPS) are of great interest, in particular whether plasma is transferred to the magnetosphere via poleward-of-cusp, lobe reconnection or via mechanisms at the flank magnetopause. This work builds on a recent case study by the authors, in which data from a wide variety of spacecraft observations, including Double Star (TC-1 and TC-2), Polar, LANL GEO and IMAGE, showed evidence of lobe reconnection in both hemispheres along with large-scale flank boundary waves. In this current study, we will present observations from the recent tail and dayside seasons of the Cluster and Double star missions, whose separation in local time presents some excellent opportunities to examine the favoured transport mechanisms for CDPS formation.
