PressureNET 2.1 Released: the Distributed Barometer Network For Android

cryptoz Re:Does it really improve local forecasts? (82 comments)

You might be right, but I don't think so. If you look at the screenshot of the analysis tool in the blog post, you can see that even through all of the noise there is a *very* clear curve for Hurricane Sandy. Although, we do know that the data is very noisy and we are working with some professors who are researching this very topic (calibration of phone sensors for weather data collection). I think we will have useful data for short-term prediction. But if not, that's okay too. Science!

PressureNET 2.1 Released: the Distributed Barometer Network For Android

cryptoz Re:Needs isobar lines (82 comments)

I agree completely! We are adding those as soon as we can. In the early days of the project, there was not enough data to build isobars. But now, we have enough and we are determined to add that feature. The project is built by me and volunteers in our free time, so it'll probably be a couple weeks or months before we get isobars in. Of course, pressureNET is fully open source and so if anyone feels like writing the isobar code and getting that feature done faster, we will welcome that too! Code is on github: https://github.com/JacobSheehy/pressureNET, https://github.com/JacobSheehy/pressureNETServer and https://github.com/JacobSheehy/pressureNETAnalysis.

Barometers in iPhones: Crowdsourcing weather forecasts

cryptoz cryptoz writes  |  about a month ago

cryptoz (878581) writes "Apple is now adding barometers to its mobile devices: both new iPhones have valuable atmospheric pressure sensors being used for HealthKit (step counting). Since many Android devices have been carrying barometers for years, scientists like Cliff Mass have been using the sensor data to improve weather forecasts. Open source data collection projects like PressureNet on Android automatically collect and send the atmospheric sensor data to researchers."

The Galaxy S4 has a Barometer - and a Humidity Sensor!

cryptoz cryptoz writes  |  about a year and a half ago

cryptoz writes "Canadian software company Cumulonimbus is building pressureNET, a free and open source Android app that taps in to the environment sensors on new phones and is now a quickly growing weather network. They're collecting about 250,000 atmospheric pressure measurements per day which they are livestreaming to scientists who are working on new methods of thunderstorm forecasting. More data density is needed first, however. Luckily, the Samsung Galaxy S4 will join the existing fleet of barometer-carrying phones which will enable further growth and better science experiments. They provide a data visualization website where you can view live graphs of the collected data."

pressureNET 2.1 released: The Distributed Barometer Network for Android

cryptoz cryptoz writes  |  about 2 years ago

cryptoz writes "Cumulonimbus has released a new version of their open source, global barometer network. The network is built around an Android app called pressureNET which uses barometric sensors in new phones (such as the Nexus 4, Galaxy Nexus, Galaxy S3, Note, and others) in order to build the comprehensive network. They plan to use the data to improve short-term weather prediction, and the gives a teaser of the new data visualization tool they are building."
