Where the figures come from

Aspen 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.

Temperature and rainfall are climate normals, averaged over the years shown. Aspen: 2006-2020 (rainfall 1991-2020) normals, Aspen / Woody Creek (5.2 km from centre). Osaka: 1991-2020 normals, Osaka (1.8 km from centre).
