Four-spacecraft determination of magnetopause orientation, motion and thickness: comparison with results from single-spacecraft methods [PDF]

Annales Geophysicae, 2004
In this paper, we use Cluster data from one magnetopause event on 5 July 2001 to compare predictions from various methods for determination of the velocity, orientation, and thickness of the magnetopause current layer. We employ established as well as
