The Wunderground.com website offers several creative interfaces to current and historic weather information. One of the more interesting features is the URL-based interface to personal weather stations. As far as I can tell, the Wunderground website only returns hourly data for a single day from personal weather stations… I wanted an entire year’s worth of data, so it made sense to abstract the process of fetching a single day’s worth of data from a named station into an R function. In this way, it is possible to quickly query the Wunderground website for arbitrary chunks of data. A semi-tested function, along with some examples are posted below. Enjoy!
