Pat Shingleton: "Hello! What's the Temp.?"
Researchers recently used Android phones to "crowdsource" air temperature readings from eight selected cities across the globe. American Geophysical Union reports that the data retrieved from smart phones correlated with temperatures recorded at weather stations. These phones include internal temperature sensors that prevent them from overheating. Software developers and atmospheric scientists were able to track battery temperatures using an "app" that permitted the capture of statistics resulting in more than 800 daily temperature readings in each city. The experiment found that the phones' temperature readings were within an average of 1.5 degrees (C) of actual temperatures in each city. Future weather predictions will incorporate phones.
