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.

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
