Description

Search Coil Magnetometer (SCM) AC Magnetic Field (32 samples/s), Level 2, Quick-Look Survey Data. The tri-axial Search-Coil Magnetometer with its associated preamplifier measures three-dimensional magnetic field fluctuations. The analog magnetic waveforms measured by the SCM are digitized and processed inside the Digital Signal Processor (DSP), collected and stored by the Central Instrument Data Processor (CIDP) via the Fields Central Electronics Box (CEB). Prior to launch, all SCM Flight models were calibrated by LPP team members at the National Magnetic Observatory, Chambon-la-Foret (Orleans). Once per orbit, each SCM transfer function is checked thanks to the onboard calibration signal provided by the DSP. The SCM is operated for the entire MMS orbit in survey mode. Within scientific Regions Of Interest (ROI), burst mode data are also acquired as well as high burst mode data. This SCM data set corresponds to the AC magnetic field waveforms in nanoTesla and in the GSE frame. The instrument paper for SCM can be found at http://link.springer.com/article/10.1007/s11214-014-0096-9.

Description

Search Coil AC magnetic vector components in GSE coordinates.

Caveats
These calibrated (nT) AC magnetic field waveform data are sampled at 32 samples/s. They are high-pass filtered above 0.5 Hz but not low-pass filtered. See global attributes for details. For more information, please have a look at the SCM Data Products Guide.
