| Zusammenfassung |
| Finding and retrieving space physics data is a rather daunting task even
when the data are publicly available on the Internet because there are
thousands of relatively small and many large data sets stored in various
formats and accompanied often only by terse documentation. Virtual
Heliospheric and Magnetospheric Observatories (VHO and VMO) are being developed
to help researches by creating a single point of uniform discovery, access, and
use of heliospheric (VHO) and magnetospheric (VMO) data. Available data
can be searched based on various criteria as, for example, spatial location,
time of observation, measurement type, parameter values, etc. The VHO and VMO
also utilize event lists to quickly narrow down searches by specific events,
e.g. bow shock crossings,flux transfer events (FTEs) or CMEs/ICMEs.
We will demonstrate the utility of VHO/VMO for geospace studies by reprising
a multi-spacecraft, multi-instrument analysis from the literature. In particular,
simultaneous observations of earthward flow bursts and plasmoid ejection during
magnetospheric substorms were identified by visual inspection of several
years of ISTP measurements by Slavin et al. [2002]. Using the VHO/VMO we
show how studies such as these can be carried out with substantial
time savings and often with the added value of accessing additional
relevant data sets that would not have been available to scientist
performing the analysis.
