Data Access
This data set includes 1-minute averages of the electric and magnetic wave spectra obtained during the period that the Galileo plasma wave receiver was operated during the Jupiter orbital mission (prime, GEM and GMM). The parameter provided for the electric field spectrum is the electric field spectral density in units of V2/m2/Hz. The magnetic field spectrum is provided in units of magnetic field spectral density, nT**2/Hz. The spectral information is averaged and binned into 49 logarithmically-spaced channels from about 6 Hz to 5.6 MHz for the electric measurements and 34 channels from about 6 Hz to 75 kHz for the magnetic. Note that these 'channels' do not generally correspond to the 158 specific channels described in the instrument description document. The reduction in spectral resolution for this data set was performed in order to make the set more conducive to use as a browse data set. The sources of this browse data set are the High Frequency Receiver, Sweep Frequency Receiver, and Spectrum Analyzer which make up the Low Rate Science portion of the PWS.

Galileo Orbiter Plasma Wave Receiver 60s Summary Dataset
Start time of a 1-minute averaging interval, starting at Seconds = 0. The time string is of the form yyyy-mm-ddThh:mm:ss.sssZ. The representation of Jan 01, 2000, 00:00:00.000 would be 2000-01-01T00:00:00.000Z.
SA channel 1. Center Frequency 5.62 Hz. The center frequencies for all densities are spaced at 8 frequency bins per decade. In order to conform to this scheme, alternate columns in the SA instrument frequency range were produced by interpolating in frequency. Also, each column is the time average of all available data in a 1-minute interval.
