VisAn MHD: a toolbox in Matlab for MHD computer model data visualisation and analysis

Abstract. Among the many challenges facing modern space physics today is the need for a
visualisation and analysis package which can examine the results from the
diversity of numerical and empirical computer models as well as observational
data. Magnetohydrodynamic (MHD) models represent the latest numerical models
of the complex Earth's space environment and have the unique ability to span
the enormous distances present in the magnetosphere from several hundred
kilometres to several thousand kilometres above the Earth surface. This
feature enables scientist to study complex structures of processes where
otherwise only point measurements from satellites or ground-based instruments
are available. Only by combining these observational data and the MHD
simulations it is possible to enlarge the scope of the point-to-point
observations and to fill the gaps left by measurements in order to get a full
3-D representation of the processes in our geospace environment. In this paper
we introduce the VisAn MHD toolbox for Matlab as a tool for the visualisation
and analysis of observational data and MHD simulations. We have created an
easy to use tool which is capable of highly sophisticated visualisations and
data analysis of the results from a diverse set of MHD models in combination
with in situ measurements from satellites and ground-based instruments. The
toolbox is being released under an open-source licensing agreement to
facilitate and encourage community use and contribution.
