MEC Datasets

Magnetic Ephemeris Coordinates (MEC)
The MEC Level-2 products are generated at the Los Alamos National Laboratory and are treated by MMS as an additional instrument team. The ephemeris products are created for each spacecraft at survey level resolution. The links below are shortcuts to where they are stored on the SDC filesystem.

For questions about the technical details of the MMS Ephemeris product, contact Dr. Michael Henderson, LANL.
