Dense Fog
Dense-fog events on TerraPulse are organized into the fog Eventdex — one slot per event,
each a measured record of a dense-fog or freezing-fog episode that actually happened, drawn from
the confirmed storm-event record. No estimates, no forecasts.

Provenance
Every event traces to the NOAA NCEI Storm Events Database and the National Weather Service (NWS) — the confirmed-event record compiled from NWS forecast offices and field reports. That source is registered against the dex, so any record on TerraPulse carries a direct line back to its originating storm report.

Each event slot carries:
- Type — dense fog or freezing fog
- Location — latitude, longitude, county, and state
- Time — begin and end time, UTC
