Sino-Magnetic Array at Low Latitudes (SMALL) including initial results from the sister sites in the United States Original Research Article

The Sino-Magnetic Array at Low Latitudes (SMALL) is an ongoing project for the development of a two-dimensional (2-D) ground-based magnetometer array in China. The ultimate array will consist of 24 stations spanning over 3 hours in local time in the low-latitude (L < 2) region. We present some initial results from the Beijing station as well as several U.S. sister sites using the same instrumentation. It is shown that the coverage, high sensitivity, and accurate timing of the SMALL array will advance our understanding of low-latitude geomagnetic phenomena.
