Updated AccessURL. Update Format of the data. Updated Parameters. A biaxial, closed loop, fluxgate magnetometer was deployed on a boom about 0.61 m long. The magnetometer, which had one sensor aligned parallel to the spacecraft spin axis and the other perpendicular to this axis, measured the magnetic field at synchronous altitude. Each sensor had a selectable range (+50, 100, 200, or 400 nT), an offset field capability (plus or minus 1200 nT in 40 nT steps), and an inflight calibration capability.

The data are sorted by year. The file names indicates the data type, spacecraft number, year, month, and resolution. For example, M0137607.FIT indicates magnetometer data (M) for spacecraft 1 (01) at 3 s time resolution (3) from July 1976 (7607). Note that spacecraft IDs 91 and 92 refer to SMS satellites, not GOES.
