Polar Magnetic Field Experiment (MFE) Data
The MFE measures the vector magnetic field in the frequency range from DC to 25 Hz [Russell et al., 1995]. The data products include the magnetic field vectors in several coordinate systems and three time resolutions: 1-minute, 6-sec, and 8 Hz/25 Hz. MFE data also help to organize and interpret the data measured by other experiments on the Polar spacecraft, especially the energetic particles, plasmas, and electric field experiments. The instrument continues to operate normally, and the size of the data to archive exceeds 1 TBytes.
The MFE data are ubiquitous in the studies based on Polar observations. In addition to the studies mentioned earlier, over a hundred refereed publications were published and they cover a wide range of subjects in magnetospheric physics. Examples such as the dynamics of the cusp at high and low altitudes [e.g., Russell et al., 2000], ring current monitoring [Le and Russell, 1998], and the unique magnetospheric response to solar wind dynamic pressure in dayside polar field lines [Fowler and Russell, 2001], constitute a small fraction of the studies using the MFE data.
The MFE data include:
- Observed B vector (GSM, GSE, SM, FAC, SC; 1-min, 6-sec, full-res.3)
- IGRF model B vector (GSM, GSE, SM, FAC, SC; 1-min, 6-sec)
- Tsyganenko model B vector (GSM, GSE, SM, FAC, SC; 1-min, 6-sec, full-res.3)
- Residual B vector with IGRF removed (GSM, GSE, SM, FAC, SC; 1-min, 6-sec)
- Residual B vector with Tsyganenko removed (GSM, GSE, SM, FAC, SC; 1-min, 6-sec, full-res.3)
