PressureNet is a network of crowdsourced weather sensors. We automatically collect atmospheric pressure measurements using barometers in new Android devices. We're sharing this live data with scientists and researchers to improve weather forecasting. Soon we'll provide you with a weather forecast based on everyone's live, shared data!
We're going to make new weather models using the data that PressureNet automatically collects - these models should produce forecasts that are significantly more accurate than any other method! Since the data is collected using smartphones, we can gather way more data about the atmosphere than ever before.
Until we make forecasts, PressureNet shows you the raw data. The pressure data is displayed in graphs so that you can see both your own data as well as other regions' graphed over time. We've just added animations as well, so you can watch storms moving across a region. Furthermore, you can now report what the weather is where you are! Current weather conditions automatically refresh every twenty minutes to keep it accurate.
PressureNet has been featured on BBC World Service, Wired Science, and MIT Technology Review.
