Smartphone Barometers Create Weather Sta

February 23 [Sat], 2013, 20:58

For a few years a handful of Android smartphones and tabletsmostly from Samsunghave come equipped with digital barometers. The idea was to help measure altitude and improve GPS accuracy. Now researchers have found a way to use these barometers for their traditional purposeweather forecasting.

An app calleddeveloped by(with help from University of Washington atmospheric scientists) creates an interface between the device and researchers. Since PressureNets most recent release in January, the researchers have been collecting about 4,000 readings per hour from the apps users. They plan to make this information available to the National Weather Service and other meteorologists worldwide.

An influx of crowd-sourced air pressure data would better pinpoint storms as they form, allowing longer response timesespecially important when dealing with relatively small but intense thunderstorms that develop quickly in areas with few official weather stations.

Thats assuming Apple and the rest of the Android community start feeling a different kind of pressure, and install barometers in their devices too.
