The Weather Channel API is currently the most popular, despite the service being only available as a paid monthly subscription. Most other Weather APIs offer a free limited account as well as paid accounts based on monthly usage.
When the Weather Channel announced in July 2012 that the company is buying one of their rivals, Weather Underground, fans of the rival weather service immediately voiced concerns about the impending Weather Channel acquisition. Such concerns include the Weather Channel's "penchant for the commercialization of weather" and the difficulty of finding historical weather data on the weather.com site.
"It was so much easier to track down historical data on the independent site (Weather Underground)" said Paul Baginski, a visiting assistant professor of mathematics at Smith College, “It seemed with every update to their Web site, weather.com added another obstacle with advertisements and extra tabs and clicks."
Since the acquisition of Weather Underground by the Weather Channel, HAMweather reported that there has been a near 300% increase in usage as developers are quickly signing up to try the free Aeris Weather API Developer accounts.
The Aeris Weather API currently supports "more than 2.6 million cities worldwide and over 7 million points of interest" and can be used for many different applications. Senior meteorologist and Media Logic Group, LLC founder Paul Douglas says that "Today, adding personalized weather to a website or mobile app is a no-brainer."
HAMweather was founded in 1996 by Lee Huffman and merged with Media Logic Group, LLC, in 2009. The company intends on continuing to focus on the weather API and data enhancement.
"Growth for a business is always the goal, but HAMweather could never forget where we come from," Said Lee Huffman, "The goal will remain what it always has been; to provide reliable and accurate weather information, for any platform, at any time."
