Voyager PWS Data Sets

The following Voyager Plasma Wave data sets are available:

• PWS Spectrum Analyzer PDS 4 bundles: voyager-1-pws-sa and voyager-2-pws-sa .
  
  
• PWS Waveform PDS 4 bundles: voyager-1-pws-wf and voyager-2-pws-wf .
  
  
• VGPW_0101: A full mission Planetary Data System (PDS) archive volume of PWS Electric Spectrum Analyzer measurements for both Voyagers 1 & 2. Note the DATATIPS.TXT file on this volume contains a concise data processing description for these data, including calibration and example code.
  
  
• VGPW_1001: Release 7 of the Full mission PDS 3 archive volume of PWS Electric Field Waveforms for Voyager 1.
  Also available as a single compressed file VGPW_1001_R7.tar.gz (6.5 GB)
  
  
• VGPW_2001: A Full mission PDS 3 archive volume of PWS Electric Field Waveforms for Voyager 2.
  
  

Note that some of these data have not completed peer review and are subject to occasional corrections and updates. Archived data sets are also available through our Outer Planets Subnode of the Planetary Plasma Interactions node of NASA's Planetary Data System.

For access to data not listed here or not currently online, contact Dr. William S. Kurth via e-mail william-kurth @ uiowa . edu.

Interactive Plots via Autoplot

The following links lead to Autoplot settings files (also called vap files). These files do not contain data, but rather tell the Autoplot program how to load data from the web. Download any of the following files and open them in Autoplot to browse Voyager PWS data holdings.

• Calibrated PWS Spectrum Analyzer data streams from PDS3 files via das2 streams for:
  • Voyager 1 Low-rate multi-channel plots with Heliospheric coordinates
  • Voyager 2 Low-rate multi-channel plots with Heliospheric coordinates
  • Voyager 2 SA Channels 1.00 - 5.62 kHz with Heliospheric coordinates
  
  
• Filtered and calibrated hourly averages and peaks from the PWS Spectrum Analyzer via PDS files for:
  • Voyager 1 Hourly average multi-channel plots with Heliospheric coordinates
  • Voyager 2 Hourly average multi-channel plots with Heliospheric coordinates
  
  
• Relative intensity PWS high-resolution spectrogram streams computed from Waveform PDS files by the das2 server for Voyager 1 in:
  • Voyager 1 High-rate spectrograms with Heliospheric coordinates
  • Voyager 1 High-rate spectrograms with Jovian coordinates
  • Voyager 1 High-rate spectrograms with Saturn centered coordinates
  
  
• Relative intensity PWS high-resolution spectrogram streams computed from Waveform PDS files by the das2 server for Voyager 2 in:
  • Voyager 2 High-rate spectrograms with Heliospheric coordinates
  
  
• Calibrated PWS Spectrum Analyzer data from PDS4/CDF files for:
  • Voyager 1 voyager-1-pws-sa
  • Voyager 2 voyager-2-pws-sa
  
  
• Spectrograms from PWS Waveforms in PDS4/CDF files:
  • Voyager 1 voyager-1-pws-wf, default time zoomed to single frame near heliopause crossing
  • Voyager 2 Uranus voyager-2-pws-wf-uranus, default time range near Uranus closest approach
  • Voyager 2 Neptune voyager-2-pws-wf-neptune, default time range near Neptune closest approach

Interactive Plots via Custom PWS Apps

The following Java 1.8 programs provide access to Voyager Low-Rate 16-channel interactive plots and High-Rate wavefrom data. These versions are standalone applications that do not require Java Web-start to function. To use them, download one of the *.jar files below, figure out where you put it, and "double-click" to run:

• vgpws_lr-1.2.1-app.jar, a standalone Voyager 16-channel interactive plotter that reads local PDS files or from das2 streams.
  
  
• vgpws_hr.jar, a standalone Voyager Waveform interactive plotter that reads local PDS files or from das2 streams.
