The barometer data that comes from phones (both Android and iOS) is extremely resilient and there is a lot of value to be derived from it. Ongoing research by Cliff Mass and team (at UW) shows that machine learning can help bias-correct and error-correct barometric pressure data on the fly with very good results. That data can also be assimilated into WRF to make forecasts with higher accuracy. I work on a related app to do that barometer data on Android: https://play.google.com/store/apps/details?id=com.allclearweather.android https://play.google.com/store/apps/details?id=com.allclearwe... (US only for now).
