Weather Underground (weather service)
|Headquarters||San Francisco, California, United States|
|Parent||The Weather Company|
Weather Underground, a commercial weather service, provides real-time weather information via the Internet. Weather Underground provides weather reports for most major cities across the world on its Web site, as well as local weather reports for newspapers and Web sites. Most of its United States information comes from the National Weather Service (NWS), as federal law specifies that information from that agency falls within the public domain. The Web site 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 (WU) is based in San Francisco, California and was founded in 1995 as an offshoot of the University of Michigan's Internet weather database. The name is a reference to the 1960s militant radical student group the Weather Underground, which also originated at the University of Michigan.
Jeff Masters, a doctoral candidate in meteorology at the University of Michigan working under the direction of Professor Perry Samson, wrote a menu-based Telnet interface in 1991 that displayed real-time weather information around the world. In 1993, they recruited Alan Steremberg and initiated a project to bring Internet weather into K-12 classrooms. WU's president Alan Steremberg wrote "Blue Skies" for the project, a graphical Mac gopher client, which won several awards. When the Mosaic Web browser appeared, this provided a natural transition from "Blue Skies" to the Web.
In 1995 Weather Underground, Inc. became a commercial entity separate from the university. It has grown to provide weather for print sources, in addition to its online presence. In 2005, Weather Underground became the weather provider for the Associated Press; WU also provides weather reports for some newspapers (including the San Francisco Chronicle) and the Google search engine. Alan Steremberg, Weather Underground's president, also worked on the early development of Google's search engine with Larry Page and Sergey Brin.
In October 2008, Jeff Masters reported that the site was #2 in Internet Weather for 2008.
In February 2010, FullScreenWeather.com was launched, a full screen weather Web tool with integrated mapping and mobile device use in mind.
On July 2, 2012, The Weather Channel announced that it would acquire Weather Underground, which will become operated as part of The Weather Channel Companies, LLC (later renamed "The Weather Company"). The Weather Underground Web site continues to operate as a separate entity from The Weather Channel's primary site, weather.com, with its existing staff retained. The Weather Company also uses the site's San Francisco headquarters as a regional office.
Web logs (blogs) are one of the main features in Weather Underground, allowing users of the site to create blogs about weather, everyday life and anything else. Jeff Masters started the first blog on April 14, 2005, and he now posts blog entries nearly every day. Richard B. Rood has been writing blogs on climate change and societal response since 2007, with new entries on a weekly basis.
Weather Underground also uses observations from members with automated personal weather stations (PWS). Weather Underground currently uses observations from over 100,000 personal weather stations. 
The Weather Underground's WunderMap overlays weather data from personal weather stations and official NWS stations on a Google Map base and provides many interactive and dynamically updated weather and environmental layers. 
The service distributes Internet radio feeds of NOAA Weather Radio stations from across the country, as provided by users. The Associated Press uses Weather Underground to provide national weather summaries.
Weather Underground has several Google Chrome extensions and applications for iPhone, iPad and Android including FullScreenWeather.com, a redirect to a full screen weather viewer tied into Google maps.
