Description
The LANL 1989-046 MPA data set contains various parameters in a variety of coordinates systems including GEI, spacecraft, polar geographic, and polar magnetic coordinates at about 87 s resolution. These parameters include universal time, denisty, velocity, and temperature for both low and high energy ions and electrons as well as position information and instrument status flags.
