Where CrowdMag
Description

In CrowdMag project, NOAA explore whether digital magnetometers built in modern mobile smartphones can be used as scientific instruments. With CrowdMag mobile apps, phones all around the world send magnetometer data to NOAA. At NOAA, we check quality of the magnetic data and make data available to the public as aggregate maps and charts. We have two long-term goals: 1) Create near-real-time models of Earth's time changing magnetic field by combining crowdsourced magnetic data with real-time solar wind data. and 2) Map local magnetic noise sources (for e.g. power transformer and iron pipes) to improve accuracy of the magnetic navigation systems.

How to Join

To join, you will need to have iOS or Android smartphone/tablet. Go to Apple or Android app stores and search for CrowdMag. After installation, enable background magnetic recording in the app. That is it!
