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

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 SH43B-02 (2)

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 Protection * Wisdom hath builded her house, she hath hewn out her seven pillars (Proverbs 9:1)

NASA 2005 ROSES Selections, Virtual Observatories for Solar and Space Physics Data Virtual Heliospheric Observatory (VHO) Standard Development for Heliospheric Data Environment Geospace and Heliospheric solar wind plasma and magnetic field data Adam Szabo / NASA Goddard Space Flight Center Virtual Magnetospheric Observatory (VMO) Multispacecraft correlative studies of the dayside magnetospheric interactions & substorms.. Jan Merka / University of Maryland, Baltimore County Virtual Magnetospheric Observatory (VMO) “Creates robust links to the world’s relevant data bases thus providing one-stop shopping for the magnetospheric researcher seeking data.” Raymond Walker / University of California, Los Angeles Virtual Radiation Belt Observatory (ViRBO) “will offer synthesized and open access to historical data, analysis and visualization software, near-real-time measurements, and the predictions of empirical models. … will foster scientific discovery and provide improved tools for satellite engineers and operators.” Robert Weigel / University of Colorado Virtual Ionosphere-Mesosphere-Thermosphere Observatory (VITMO) Integrates TIMED, AIM, C/NOFS, SuperDARN, CDAWeb, SSCWeb, ModelWeb. Daniel Morrison / Johns Hopkins University Applied Physics Lab

VHO Development Phases (3) Full VHO Connection to processing services. Connection to other VxOs
15
Types of VHO searches Offer 5 types of data searches: 1.HGI Latitude/Longitude/Radial Distance 2.Spatial Region, Inner Heliosphere, etc. 3.Bartel Rotation 4.Near Earth - GSM/GSE 5.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)

VHO Data Participants 8 Spacecraft - 13 Data Sets ACE - Magnetometer - SWEPAM Genesis - Mag. Field Proxy - 3D Moments Helios 1 and 2 - Magnetometer - Plasma instrument IMP 8 - Magnetometer SOHO - Celias instrument WIND - MFI - SWE - ELPD - PLSP Mars Global Surveyor -Solar Wind Pressure Proxy SH43B-02 (4)

Search Options Data can be searched for by the following ways: Time Date/Time Bartel/Carrington Rot. S/C Location GSE/GSM/HGI coord. Region name Measurement Type e.g., magnetic field, thermal plasma, energetic particles View selection here Make selection here
18
Demo VHO API The VHO API can connect user written programs to VHO functionality without going through a browser. An IDL Virtual Machine program will be distributed by the VHO team to demonstrate the VHO API. Demo will allow search and simple visualization of data.
