The VWO
Why VWO?

• Goal
• To make Heliophysics wave data searchable,
  understandable and usable by the Heliophysics
  community
• Objectives
• To provide uniform access to distributed space
  plasma wave and radiation data, metadata, and
  services to support wave-oriented research
• To extend Heliophysics Virtual Observatories to
  cover wave-specific datasets that span most
  Heliophysics domains solar wind, interplanetary
  space, terrestrial magnetosphere and ionosphere,
  and planetary magnetospheres
• To make wave phenomena and data accessible and
  understandable to non wave-oriented users

Abstract Heliophysics wave data are currently not
easily searchable by computers, making
identifying pertinent wave data features for
analyses and cross comparisons difficult and
laborious. Since wave data analysis requires
specialized knowledge about waves, which spans
the spectrum of microphysics to macrophysics,
researchers having varied expertise cannot easily
use wave data. To resolve these difficulties and
to allow wave data to contribute more fully to
Heliophysics research, we are developing a
Virtual Wave Observatory (VWO) whose goal is to
enable all Heliophysics wave data to become
searchable, understandable and usable by the
Heliophysics community. The VWO objective is to
enable searches of multiple and distributed wave
data (from both active and passive measurements).
This presentation provides an overview of the
VWO, a new VxO component within the emerging
distributed Heliophysics data and model
environment.
VWO Services
Community Needs

• To search, access and use
• Wave data in distributed archives (Iowa, CAA,
  UMass, NSSDC, PDS, etc.)
• Current mission wave data (e.g., THEMIS, Geotail)
• Data services, such as VxOs, CDAWeb, etc., for
  ancillary data
• Particle and field
• Space environmental and context conditions
• Models

VWO will enable cross-comparisons of heliophysics
wave environments
