Search coil magnetometer data from BAS AGOs in Antarctica

Search coil magnetometer data are primarily used to study waves and transient variations in Earth's magnetic field in the ULF (Ultra-Low-Frequency) range, from ~0.001 Hz to 5 Hz. Naturally-observed ULF signals in Earth's magnetic field are almost exclusively produced by physical processes in Earth's ionosphere and magnetosphere as consequences of the interaction between the solar wind and Earth's space environment. The data in this set is recorded at a rate of 2 samples/sec. at the following British Antarctic Survey (BAS) Automatic Geophysical Observatories (AGO): AGO A80 (80.7 deg S, 20.4 deg W) AGO A81 (81.5 S, 3.0 E) AGO A84 (84.4 S, 23.9 W)
