4 Stations StationGeog. Lat. [°S]Geog. Lon. [°E]Local Time [hr]L-Shell Macquarie Island UT Mawson UT Davis UT Casey UT + 7- Scott Base UT Search-coil induction magnetometers. Data are typically sampled at 2 Hz (up to 8Hz for campaigns). Noise of 0.5 nT peak-to-peak at 5 mHz. 6 dB/octave frequency response to 0.2Hz, then constant with frequency. Daily calibration between 16:30 – 16:40 UT. Timing linked to GPS. Accurate within 50 ms. Data recorded continuously from H and D components recorded. Data are currently available by request to: Summary dynamic spectra are available. Data must be calibrated if physical units [nT] are required.
