Methodology & sources
Quito
Temperature & precipitation — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.
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.
Vientiane
Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Wattay Intl, a weather station, about 5 km from the city centre. The underlying daily records come from NOAA's global station network.
