Open-Meteo vs openSenseMap
Open-Meteo is an open-source weather API that blends forecast and historical data from national weather services like NOAA, DWD, and Meteo-France, automatically selecting the highest-resolution model available for a given location. It requires no API key for non-commercial use and covers specialized domains including marine conditions, air quality, flood risk, and long-range climate projections.
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.
