PressureNET 2.1 Released: the Distributed Barometer Network For Android

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."

Re:Why do the phones have barometric sensors?

[Anonymous Coward]

I thought it was pretty interesting that phones would include barometric sensors which I had not heard of before - are they just there in a package with other more commonly used sensors? How do the phones that have them normally make use of or present that data?

Makes GPS system start up faster.

They were originally added to assist with navigation (they double as an altimeter, sensing pressure changes due to elevation) allowing the phone to acquire GPS lock quicker by using the data in conjunction with latitude and longitude calculations.

Re:Needs isobar lines

[cryptoz]

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 [github.com], https://github.com/JacobSheehy/pressureNETServer [github.com] and https://github.com/JacobSheehy/pressureNETAnalysis [github.com].
