This page shows weather data collected mostly by privately owned and operated weather stations. Stations with a CW-prefixed, numbered callsign are taking part in the Citizen Weather Observer Program (CWOP). Most other weather stations are amateur radio operators with a weather station. Some information is also converted by individuals from publicly available sources like airport weather reports.
