How these figures are read
The publisher marks estimated values with *, missing months with ---, and sunshine read by an automatic Kipp & Zonen sensor with #. Missing months are excluded from every ranking on this page; they are never read as zero. Ties share a rank.
We archive the publisher’s file verbatim every time we fetch it, so the figures above can always be checked against the exact version they were read from: data/weather-stations/raw/2026-10-08/armaghdata.txt.
