What is the name of a commercial weather service that provides real-time weather information reported by personal weather stations that have access to this international website?
Weather Underground (weather service) Weather Underground is a commercial weather service providing real-time weather information via the Internet. Weather Underground provides weather reports for most major cities across the world on its website, as well as local weather reports for newspapers and websites. Its information comes from the National Weather Service (NWS), and over 250,000 personal weather stations (PWS). The website is available in many languages, and customers can access an ad-free version of the site with additional features for an annual fee. Weather Underground is owned by The Weather Company, a subsidiary of IBM.
PMX (technology) PMX refers to the technology developed by Pelmorex to generate local weather information on The Weather Network. PMX consists of computers, typically installed at a cable headend, that takes data fed to it (the video feed of The Weather Network, forecast information, and triggers to run said forecasts) and packages it for broadcast. Unlike the Weather Star systems, it does not generate full graphical or video segments, rather the information is super-imposed over the main video feed.
