Polar HYDRA 14-sec Moments

Metadata Updated: July 11, 2025

This data set from the POLAR Hot Plasma Analyzer (HYDRA) contains survey electron and proton moments for density, bulk velocity (GSM), and temperature in parallel and perpendicular directions at 13.8-second resolution as determined for s/c potential at 0-20keV. Higher quality data products may be available from the P.I. The direction designations "parallel,""perpendicular," and "antiparallel" refer to the magnetic field and indicate sample averaging over pitch-angle ranges of 0-30, 75-105, and 150-180 degrees.
