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:

Data Products Guide
Each of the instruments of the FIELDS investigation have data product guides that describe the details of their products, including variable lists, caveats, and algorithms. In addition, the FIELDS investigation as a whole has provided an overview Data Products Guide that contains information necessary to the analysis of the data.
