What dimensions of quality should be considered?
- Quality control
- Error bar
- Missing data
- Contamination (weather, clouds)
- Instrument error (recalibration)
- stability
- Cross instrument consistency
- Quality assurance (someone tags it as valid)
- Useful metadata provided?
- Subjective scaling (e.g. quality judgement with range 0-5)
- Instrument Verification and Validation
- Data processing
- Re-processing tag and notification
- input errors and forcings
- re-gridding
- missing data
- Usage issues
- High enough resolution?
- Valid inference about what is measured
- Chain of Custody (for legal use)
Strategic breakdown
- Instrument (accuracy, completeness, consistency)
- Environment (cloud)
- Processing
3rd party ratings
- NCDC Certified data (only states that it is in the archive)
- DIF records have some minimum required fields to accept; then have a text field to describe quality
- Testimonials
- Peer review
- Maturity Model approach for data (John Bates)
- Level of maturity (five levels of improved treatment)
- ECHO has "measured parameters" from ECS model
- QA percent cloud cover; missing pixels;
Additional Questions
- What common data quality standards can the Federation offer within the Earth Information Exchange?
- How can we enforce these standards within the Earth Information Exchange?
- Are there similar ratings for "data services"?
