Detected dust episodes
Automatic list of Saharan dust episodes by island from the hourly AOD series.
We group each run with AOD above the operational threshold for several consecutive hours into a single episode. This is automatic detection for context, not a replacement for official bulletins.
Criteria
AOD 550 above the light dust threshold for at least 3 consecutive hours; if a gap exceeds 2 hours we start a new episode.

The latest valid reading is no longer recent
We are still showing the latest reference available, but it is already older than the 4-hour freshness window we use for this site.
Known signal: The latest automatic refresh finished on Aug 1, 2026, 7:35 PM, but no reading newer than Aug 1, 2026, 1:00 AM arrived. This points to a delay or pause in the source feed, not necessarily maintenance.
The official portal can take several minutes to refresh. We retry the automatic update every 10 minutes.
