| Zusammenfassung |
| This paper reviews the main advances in the area of data-based modelling of
the Earth's distant magnetic field achieved during the last two decades. The
essence and the principal goal of the approach is to extract maximum
information from available data, using physically realistic and flexible
mathematical structures, parameterized by the most relevant and routinely
accessible observables. Accordingly, the paper concentrates on three aspects
of the modelling: (i) mathematical methods to develop a computational
"skeleton" of a model, (ii) spacecraft databases, and (iii)
parameterization of the magnetospheric models by the solar wind drivers
and/or ground-based indices. The review is followed by a discussion of the
main issues concerning further progress in the area, in particular, methods
to assess the models' performance and the accuracy of the field line mapping.
The material presented in the paper is organized along the lines of the
author Julius-Bartels' Medal Lecture during the General Assembly 2013 of the
European Geosciences Union. |
