The Community • Space physicists • Concentrated in N. America and Europe (approx. 300 researchers) • Affiliated with the American Geophysical Union • space physics and aeronomy sub-division
Description: System • Goals • Real-time remote control of instruments • Access to archival and real time data • Communication with remote colleagues • Evolution • Organized campaigns • Impromptu campaigns and monitoring
Description: History • UARC v.5 (pre-web era) • NeXTstep-based system, 1992-97 • UARC v.6 • java applet-based system, 1996-98 • SPARC • Web-based, thin client system, 1999 - present
Current SPARC Interface • Live demo! • http://sparc-1.si.umich.edu/sparc/central
Description: Funding • UARC (IRI 9216848) • cooperative agreement between Michigan and NSF CISE & ATM • approximately $800 K per year, 1992-97 • SPARC (ATM 9873025) • KDI award from NSF CISE • approximately $500 K per year, 1997-01
Description: Organization • 14 investigators • 3 computer science • 2 human-computer interaction • 9 space physics • 15 students • 6 computer science • 6 human-computer interaction • 3 space physics • 8 staff • 7 programmers • 1 system administrator
Description: Incentives • Funding • scientists recruited through sub-contracts • Recognition • innovative system • highly visible to space science and computer science communities • Novel capabilities • new ways of combining data • respond to opportunities (e.g., UCB sounding rocket campaign)
Data Sources and Characteristics • Observational and model • Real-time and archival; dirty vs. clean • Web-scrapping into flat files • Access to community databases (e.g., CEDAR, CDAW)
Access: Instruments • Observational • ground-based • active • incoherent scatter radar (e.g., convection reversal boundaries) • all-sky cameras (e.g., auroral morphology) • interferometry (e.g., winds) • passive • riometry • magnetometer chains
Access: Instruments (cont.) • Observational • space-based • satellite imagery (UV and visible light) • shuttle imagery • sounding rockets • Theoretical • computational simulations
Sondrestrom observatory Sondrestrom, Greenland
Technology involved • 1992-97 • UARC v.5 built on NeXT machines, migrated to NeXTstep OS • 1996-98 • UARC v.6 built as java applets (MURAL), Web-based • 1998 to present • SPARC built as thin client (e.g., HTTP), migrating toward CHEF-based system (e.g., portlet technology)
Success and challenges • Scientific • first simultaneous real-time display of incoherent scatter radar chain (April, 1998) • first combined real-time simulation and observation campaign (April, 1997) • first archival campaign (December, 1993) • Educational • first student campaign (February, 1995) • Future • model for dozens of collaboratory efforts

Total sessions per year • Arrival of web • Internet usage
Simultaneous scientific useSeptember 22, 1999 - May 2, 2000 Y2K shutdown Missing data Fire in server building
Simultaneous scientific use with chatSeptember 22, 1999 - May 2, 2000 Radar campaign LTCS campaign Geophysical world days Workshop
Shift in Usage Patterns • Campaigns • Real-time monitoring • Archival data access • Island Community Networks (meta-data standards, XML, and Z39.50)
Key findings, 2001 • Some use of data intensive websites; concentrated with core users • No predominant community web or data sites • Scientists do not read core space science journals on-line • Low use of collaboration technologies • Data conferencing • Videoconferencing
