Methodology & sources

Edmonton

Temperature & precipitation — 1991–2020 normals computed from 25 years of daily observations at Edmonton Woodbend, a weather station, about 24 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.

Big Sky

Temperature & precipitation — 1991–2020 normals computed from 22 years of daily observations at West Yellowstone, a weather station, about 73 km from the city centre. The underlying daily records come from NOAA's global station network.
