SuperMAG In The RBSP Era
Past Present Near Future

2. What is SuperMAG?
SuperMAG is a global collaboration that provides ground magnetic field perturbations from a long list of stations in the same coordinate system, identical time resolution and with a common baseline removal approach.
The collected and processed high quality ground based magnetic field data provide a unique capability of addressing the global spatiotemporal behavior of the large-scale ionospheric electric current system and its coupling to the magnetosphere.
However, the inherent problems with ground magnetometer data can complicate or even prevent global studies. Data are provided in a variety of file formats, temporal resolutions, units, coordinate systems and are provided with or without some baseline subtracted.
SuperMAG is:
- Fully operational and online at
- Funded by both NSF and NASA
- SuperMAG is the logical way forward for the ground magnetometer community

5. SuperMAG And RBSP
While real-time data is not currently served by SuperMAG, the comprehensive data handling software package has no inherent problems dealing with real-time data. This includes:
- determine and rotate to local magnetic coordinate system
- determine and subtract baselines
The website can:
- ingest and display real-time data
Relevant science:
- Empirical magnetic field models (TS-like modelling)
- Global monitoring of Pc-1 to Pc-5 pulsations (RB mechanisms: EMIC/ULF waves)
- Global ionospheric currents and their coupling to the magnetosphere
SuperMAG is ready to serve the RBSP community.
