Where the figures come from

Killarney's temperatures are measured 53 km from the centre, at Valentia Observatory.

Killarney has no rain gauge within 25 km of the centre, so its rainfall comes from a gridded climate dataset read at the city rather than from a gauge further away.

Siem Reap has no weather station within reach, so its figures come from a gridded climate model rather than a measured record, and read a broad area rather than the city itself.

Temperature and rainfall are climate normals, averaged over the years shown. Killarney: 1991-2020 normals, Valentia Observatory (52.7 km from centre). Siem Reap: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km.
