⑥ Sources & calibre
Calibre: observed — values come from monitoring stations and satellites, no model forecast. Entries backfilled from the forecast archive are labelled as such and never mixed in.
⚠ Gap notes and source annotations below are currently written in Chinese only — they are shown untranslated rather than omitted, so no information is lost.
