WHAT WOULD CHANGE THIS STATUS?
A side-by-side calibration run against the reference station would move this to Verified or close it as an instrument fault. A documented maintenance error would explain the discrepancy with no issue remaining.
Every record states in advance what evidence would move it. A status is a current reading of the evidence, not a verdict.
Local context
A community sensor network reports values that diverge sharply from the nearest reference station. Residents do not know which reading to trust.
Who is affected: Residents of two neighbourhoods (synthetic).
Evidence
Evidence summary: Two synthetic datasets that conflict. No reconciliation performed.
Evidence here does not mean absolute truth. It means: a record exists, with a source, a date and a provenance, and it has reached the review stage shown below.
Community low-cost sensor series showing elevated particulate levels.
- Source
- Community sensor network (synthetic)
- Evidence submitted
- 1 Jun 2026
- Provenance
- Uncalibrated low-cost devices; no co-location test performed.
- Evidence reviewed
- Not reviewed
Conflicting evidence
The reference-station series for the same period shows no comparable elevation.
Reference-station series for the same period.
- Source
- Reference monitoring export (synthetic)
- Evidence submitted
- 3 Jun 2026
- Provenance
- Instrument-grade export, but sited 4 km from the community sensors.
- Evidence reviewed
- Not reviewed
Conflicting evidence
Does not resolve whether a local source exists between the two sites.
What is needed
- Co-location calibration test
- Metrology review
- Neutral data reconciliation
- Plain-language explanation for residents
Proposed solutions
No active proposal. This issue is waiting for someone who knows how to approach it.

Updates
- OBSERVATION· Local contributor
Residents report conflicting air-quality numbers.
- INTERPRETATION· Reviewer
Conflict is unresolved. Neither dataset should be presented as settled.
Outcome
No outcome recorded yet. This is the current evidence-backed state of the issue, not a final conclusion.
