NASA View of Heliophysics Data Environment

• Data from the Heliophysics Great Observatory
  (HGO) reside in a distributed environment and are
  served from multiple sources.
• Multi-Mission Data Centers
• Solar Data Analysis Center
• Space Physics Data Facility CDAWeb, OMNIWeb,
  SSCWeb, HelioWeb, etc.
• The Community Coordinated Modeling Center (CCMC)
• National Space Science Data Center (NSSDC)
  final permanent archives
• Mission-level active archives e.g. ACE, TIMED,
  TRACE, Cluster, Ulysses, Voyager, planetary
  mission data sets - Planetary Data System
• Full mission legacy archives ISEE-1/2/3,
  IMP-1/../7, Pioneer-6/..11
• Many HDE data sets served from individual
  instrument sites.
• NASA Heliophysics program now funding a new data
  environment
• Virtual Observatories for convenient search and
  access of the distributed data, and
• Post-mission archives to retain the distributed
  data sources at mission instrument team sites
  even after mission termination

• CDAWeb
• Easy data browse and display, user-specified
  time and parameter subsets with graphics,
  listings, file downloads
• Data from most instruments on most current
  (non-solar) LWS missions 1992-2006 Most
  recent TIMED data and Cluster Prime Parameters
• Working with new missions THEMIS, STEREO,
  TWINS, and IBEX
• All data in CDAWeb also available through
  web-services API
• E.g., Level-2 THEMIS products to related VxO
• Mirror sites in England (RAL), Germany (MPE),
  Japan (ISAS)
• THEMIS
• THEMIS data products
• Orbit predicts in GSE until 2009 (Oct 2006
  update)
• Preparing to serve Level-2 data,
• Supporting the correct definition of Level-1
  CDFs
• Would like to include THEMIS-specific IDL code
  for data display

Why Virtual Observatories ?

• Many datasets with large volumes
• Data sites distributed worldwide
• Stored in a variety of formats
• Accessible through a wide variety of interfaces

What is a Virtual Observatory, according to
NASA? A Virtual Observatory (VO) is a suite of
software applications on a set of computers that
allows users to uniformly find, access, and use
resources (data, software, document, and image
products and services using these) from a
collection of distributed product repositories
and service providers. A VO is a service that
unites services and/or multiple repositories.
The Seven Pillars of Wisdom for Virtual
Observatory Functions 1. Coordinated Discovery
and Access 2. Understanding of Data Needs 3.
Standards and Metadata 4. APIs and Web
services 5. Value Added Services 6. Ancillary
Data Access 7. Usage Assessment and Provenance

builded her house, she hath hewn out her seven

• Connection to processing services.
• Connection to other VxOs

15
Types of VHO searches

• Offer 5 types of data searches
• HGI Latitude/Longitude/Radial Distance
• Spatial Region, Inner Heliosphere, etc.
• Bartel Rotation
• Near Earth - GSM/GSE
• Near Earth Spatial Region, Bow Shock to 60 Re
• Data is from solar wind only, magnetospheric
  data has been removed
• Query Language is VHO version of SPASE Data Model
• SPASE (Space Physics Archive Search and Extract)

The VHO API can connect user written programs
toVHO functionality without going through a
browser.
An IDL VirtualMachine programwill be
distributedby the VHO teamto demonstratethe
