Short summary
We highlight the development of a low-cost portable sensor array to study magnetic fields in urban areas. Recent advancements in urban science have demonstrated significant utility in characterizing a city based on physical measurements. Magnetic fields of cities are characterized by significant noise; in the case of the San Francisco Bay Area, this noise is dominated by the BART train system. We demonstrate an ability to identify and extract BART noise from the urban magnetic environment.
