What the listing says

Latest surface observation from the nearest National Weather Service station to a US coordinate, with the station identity, the observation time (observed_at), its age in seconds and an is_stale flag. Station observations are reported roughly every 20-60 minutes, so this is the most recent measurement, not a real-time reading. Readings that fail the station's quality control are returned as null. Use when: What was the most recently observed temperature at these US coordinates?
