Where the figures come from
Copper Mountain's temperatures are measured 35 km from the centre, at Leadville / Stringtown.
Copper Mountain 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.
Rio de Janeiro 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. Copper Mountain: 2006-2020 (rainfall 1991-2020) normals, Leadville / Stringtown (35.2 km from centre). Rio de Janeiro: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km.
