Methodology & sources
Canberra
Temperature & precipitation — 1991–2020 normals computed from 25 years of daily observations at Canberra Forestry, a weather station, about 3 km from the city centre. The underlying daily records come from NOAA's global station network.
Cloud, humidity, wind & sunshine — modelled estimates from NASA POWER, NASA's satellite-and-reanalysis climatology. This is the standard global source for atmospheric variables, which are not measured at most weather stations.
St. Louis
Temperature & precipitation — the official 1991–2020 climate normals from NOAA's U.S. Climate Normals, measured at ST Charles 7 Ssw (NOAA GHCN station USC00237398), about 29 km from the city centre.
