The current and next generation of space physics missions require a means to display from tens to hundreds of time series of data in such a way that the mind can comprehend them for the purposes of browsing data, retrieving them in directly useful form, and analyzing them in a global context. Sets of many spacecraft, each carrying many instruments yielding nearly continuous data at high time resolution have become one of the most effective ways to make progress in understanding the extended, ionized (plasma) atmosphere of the Earth and the Sun.

ViSBARD provides a way of visualizing multiple vector and scalar quantities as measured by many spacecraft at once. The data are displayed three-dimesionally along the orbits which may be displayed either as connected lines or as points. The data display allows the rapid determination of vector configurations, correlations between many measurements at multiple points, and global relationships. Things such as vector field rotations and dozens of simultaneous variables are very difficult to see in (complementary) panel plot represtations.

With the addition of magnetohydrodynamic (MHD) model data, this environment can also be used to 1) validate simulation results with observed data, 2) use simulated data to provide a global context for the sparse, observed data, and 3), apply feature detection techniques to the simulated data.

Data can be loaded locally, retrieved remotely from within the application via the Virtual Space Physics Observatory, CDAWeb, or SSCWeb. Alternatively, data can be "pushed" from the VSPO to ViSBARD via the "View in 3-D" button available for supported data products.

ASCII or CDF formats are supported, with either a header or a simple "resource description file" that specifies how the file is formatted. This RDF can be automatically generated when loading a new CDF file via a built-in interface that allows the user to select which variables to import.
