A day runs from midnight to midnight local time; a daily average needs at least 18 of 24 hours measured. Model estimates do not count.

≥ means at least: the station is missing more than a tenth of the days or hours, so it ranks lower than it would with complete readings.

Grey at the end: stations with 0 but too few readings, and, marked ³, stations whose unverified hourly values jump unusually strongly. We compare neither with the allowed number.
