  1. Data search & distribution

  2. Existing GONG DSDS • Data Storage & Distribution System

  3. Quick-Look • For space weather applications, speed is of the essence. • Currently get hourly magnetograms automatically returned. • Yan Li’s page • Expect to have near real time full data delivery in about a year.

  4. But… • Quick-look data will not be optimally calibrated. • Optimal calibration currently uses a 60-day running mean. • How optimal is “good enough”?

  5. Trade-Offs • Is (1, 2, 6, 12, 24) hours after acquisition good enough for space weather? • Is an approximate calibration good enough? • Need to estimate cost/benefit of various delays in data availability.

  6. Requirements & User Models • Some user models: • Rapid availability for predictive capability. • Best calibration for detailed studies. • Happy with jpegs. • High cadence for dynamics. • Low cadence for morphology. • Event driven. • One-click shopping. • Diverse requirements

  7. Integration into Existing Systems • GONG DSDS • Need better interface • Automatic posting of summary images • Virtual Solar Observatory • Needs on-line data

  8. More Questions • Are specialized tools need for data searching? • Visualization • Region extraction • Should the older data be processed and distributed? • Zero point will be high • Will test pipeline • Cost will be high
