Stations

Every station is a first-order NWS site that issues a Daily Climate Report (CLI), which is the truth for that station. The climatological day is local standard time all year, so each station carries a fixed UTC offset and daylight saving is never applied (methodology §2.1).

Scored days are for lead day 1, the last 90 days, 00Z, bilinear, daily maximum — the default view. A station with no number has no scored day in that view yet.
