The FP-7 SPACE project IMPEx (Integrated Medium for Planetary Exploration) is building a web-based research environment for planetary plasma science, aiming to facilitate comparison of in situ measurements and computational models. Several observational and simulation databases with common metadata standards provide datasets that can be combined, compared and visualised with online tools or downloaded for analysis with personal favourite software. The Finnish Meteorological Institute’s (FMI) Hybrid Web Archive (HWA) contains simulations of the plasma environments of several Solar System objects, such as Venus and Mars, modelled with the HYB hybrid code. HWA also includes the GUMICS Earth Archive, which contains simulations of the Earth’s magnetosphere performed with Europe’s only global magnetohydrodynamic code GUMICS-4 (Grand Unified Magnetosphere–Ionosphere Coupling Simulation). The simulations can be examined online at http://hwa.fmi.fi/beta/. HWA implements the IMPEx data access protocol, allowing downloading of the simulation data via a SOAP-based web service interface. In this presentation we illustrate the use of the IMPEx / FMI-HWA web services directly from the Matlab command line, using a Matlab function package written for this purpose. The freely available package includes functions for specifying sets of points in space, e.g. on a surface or along a spacecraft trajectory, for retrieving simulation data at the specified points and for reading the data into Matlab variables.
