stationsEvery station, active or not: kind, region, position, depth, what it reports, its owner, and the terms its data are shared under.

Readings older than 90 days are thinned to about one an hour.

Levels older than 60 days are kept on the hour.

Only good vectors: two or more radars, horizontal dilution of precision at most 2.

For questions over months or years without reading every reading. Days older than 90 days are summarised from readings kept about hourly, so a brief peak between them can be missed.
