University of Washington atmospheric scientists are paddling in to the citizen science crowdsourcing wave.
They’ve released a free Android app called pressureNET for tablets and smartphones to collect and map barometric pressure data around the world. They hope to improve short-term, local weather forecasting with the flood of new readings.
PressureNET, now installed on more than 10,000 devices, makes use of pressure sensors built into a growing number of smartphones and tablets. The newest version of the app provides a lives stream of data to scientists and forecasters.
"With this approach we could potentially have tens or hundreds of thousands of additional surface pressure observations, which could significantly improve short-term weather forecasts," says Cliff Mass, a UW atmospheric sciences professor.
