- Magnetic field data from the phone's magnetic sensor
- Time of measurement
- Location of measurement
- Location accuracy
- The model of your phone (and thereby, we will know which type of sensor was used to collect the magnetic field data)
Your voluntarily shared data are stored in an internal, non-public database at the NOAA's National Centers for Environmental Information, Boulder, CO, U.S.A. Since we do not collect any personally identifiable data from your phone, it is not possible to uniquely identify data from a specific phone in the database. The data will be stored for an indefinite period of time to benefit the research community. Our magnetic field research team will use this data to assess the utility of incorporating crowdsourced magnetic field data for modeling Earth’s magnetic field. Using CrowdMag data, our team will periodically produce scientific products such as maps, graphs and/or mathematical models. In order to further geomagnetic field research, these products may be presented at meetings, be included in publications, or be made available to the public via the Internet. If you have concerns or questions on the use of these data, please contact us at email@example.com.
