Monitor guidance
Source availability and status
Status wording distinguishes successful zero observations from unavailable source evidence.
Near-real-time states
- Operational
- Both governed sources succeeded for the accepted release.
- Degraded
- One source failed and the available source was published. The failed source is unavailable, not zero.
- Stale
- The last accepted release is older than the configured threshold. Valid records remain visible with publication age and latest acquisition time.
- Valid empty
- Source processing succeeded but the selected Ghana window contains zero retained detections.
- Initialising
- No accepted public release exists yet.
- Unavailable or error
- The pointer, contract, release or selected window could not be loaded or validated.
Historical states
- Available with records
- The selected UTC date has retained detections.
- Available zero records
- Expected observations were available and valid but no Ghana detections were retained.
- Source missing
- Expected source observations are missing, so zero activity cannot be inferred.
- Structurally unavailable
- A sensor did not yet have governed support for that date.
- Partial
- The date belongs to a source year with incomplete temporal coverage.
Interpreting counts
Unavailable sensors are labelled unavailable. They are never converted to a zero count. Displayed detections reflect the current filters, whereas source status describes whether the underlying observations were available and successfully processed.
