AviationWeather vs openSenseMap
The legacy Text Data Server referenced by the original dataserver URL has been discontinued and replaced by the new Aviation Weather Center Data API, reachable at aviationweather.gov/data/api. It serves worldwide METAR/TAF, US/North-Atlantic PIREPs, global SIGMETs, and CONUS G-AIRMETs (which replaced text AIRMETs in January 2025) in raw text, JSON, GeoJSON, CSV, XML, or IWXXM, with no authentication but a 100-requests/minute rate limit.
openSenseMap is the open, non-profit citizen-science platform behind the University of Munster's senseBox project, serving live and historical readings from thousands of crowdsourced environmental sensor stations worldwide, covering not just temperature/humidity but also particulate matter, noise and other phenomena. Reading data is fully open and keyless (accounts are only needed to register or post data from your own senseBox), and the full historical archive is separately mirrored on an archive subdomain.
