FIELDS Datasets

FIELDS
The FIELDS investigation includes a sensor suite consisting of two axial and four spin-plane double-probe electric-field sensors (ADP and SDP), two flux-gate magnetometers (AFG and DFG), a search-coil magnetometer (SCM), and two electron drift instrument (EDI) per MMS spacecraft. These instruments measure the DC magnetic field with a resolution of 10 ms, the DC electric field with a resolution of 1 ms, electric plasma waves to 100 kHz, and magnetic plasma waves to 6 kHz (Torbert et al., 2014).

For questions about the technical details of the FIELDS instrument suite, contact the FIELDS Lead Co-I: Dr. R. B. Torbert, UNH. As FIELDS consists of five subsystems, questions about particular packages may be addressed to the following as well:
