| Zusammenfassung |
| The magnetospheric boundary is always moving, making it difficult to
establish its structure. This paper presents a novel method for tracking the
motion of the boundary, based on in-situ observations of the plasma velocity
and of one or more additional observables. This method allows the moving
boundary to be followed for extended periods of time (up to several hours)
and aptly deals with limitations on the time resolution of the data, with
measurement errors, and with occasional data gaps; it can exploit data from
any number of spacecraft and any type of instrument. At the same time the
method is an empirical reconstruction technique that determines the
one-dimensional spatial structure of the boundary. The method is illustrated
with single- and multi-spacecraft applications using data from Ampte/Irm and
Cluster. |
