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 Holmes-Bredekamp 2006

With Bowshock Plasmapause and Geotail and FAST in GSE coordinates

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 Access2. Understanding of Data Needs3. Standards and Metadata4. APIs and Web services5. Value Added Services6. Ancillary Data Access

7. Usage Assessment and Provenance Protection

• Connection to processing services.

• Connection to other VxOs

Types of VHO searchesOffer 5 types of data searches:

1. HGI Latitude/Longitude/Radial Distance2. Spatial Region, Inner Heliosphere, etc.3. Bartel Rotation4. Near Earth - GSM/GSE5. 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 ModelSPASE (Space Physics Archive Search and Extract)
