WAKEATLAS / EVIDENCE AND FRESHNESS

How current is our data?

Different feeds update at different times. This page shows what WakeAtlas can verify, including delays and missing monitoring.

Page assembled: 2026-10-28 07:04:46.857Z. Internal summaries may be cached for up to one minute. Refresh to check again.

Four different clocks

Model run / issue: when a forecast was produced. Valid time: when its prediction applies. Observation / image time: when a measurement or image describes the world. Retrieved: when WakeAtlas downloaded it. A successful download does not make old observations current.

Thresholds below are WakeAtlas display checks, not provider service guarantees or proof of accuracy. One fresh station does not establish fresh coverage everywhere. Unavailable means this check could not obtain evidence, not necessarily that the provider is offline.

All queued locations cached within 8 hours

571 of 571 queued locations cached; 0 caches older than eight hours. Backoff remaining: 0 seconds.

Locations are normally refreshed about every six hours, subject to quota and retry delays. Each buoy or platform forecast shows its own retrieval and valid times. A provider model issue time is not centrally reported; download time must not be used as a substitute.

Scheduled metadata and atlas refreshes

These checks run without a visitor opening the layer. Sentinel checks cover the bounded UK pilot region, not the world. A successful catalogue check does not verify every image pixel. GFW checks its published version and refreshes snapshots automatically. Previous activity data remains available until a complete replacement is validated.

Other collection intervals

Earthquake and tsunami checks run about every minute; maritime-security feeds about every ten minutes; port-intelligence feeds about every twenty minutes. Provider checks and failures appear below. These are polling intervals, not guarantees of new reports.

Buoy and cyclone collectors normally check every ten minutes. PortWatch and Argo collection records are assessed against a daily schedule. Historical-ship and wreck research are updated on demand, when material is available. The collection cards above show the last recorded evidence.

Satellite weather catalogues are checked hourly in the background and may also refresh on demand after five minutes. Individual satellites have different image times, shown in the satellite section. Daily Terra and NOAA-20 mosaics can be incomplete during the current day; transparent gaps are not cloud-free observations.

Reference-source pages are checked daily; changed pages require review before stored survey or historical data are replaced. Tile cache expiry follows provider rules and is not a satellite collection timer.
