An Android app that measures atmospheric pressure is now feeding that distributed data to scientists working on better ways to predict the weather.  The app, called Pressure Net, highlights the potential of distributed sensing using mobile devices and shows how the sophisticated sensors found in modern smartphones could be harnessed for research. It was launched in late 2011 By Jacob Sheehy, a software developer for, and Phil Jones, an independent Web designer, who became friends while studying at Concordia University in Montreal.  CoEnv Atmospheric Sciences Professor Cliff Mass is helping figure out how to incorporate the data into climate models.  Read more about how this all works.
