Hourly Solar Wind Data from Multiple Spacecraft

Hourly-averaged near-Earth and deep space solar wind magnetic field and plasma measurements from over 15 spacecraft missions, including ACE, Wind, Voyager, and Ulysses. The data is spacecraft-interspersed and provided by NASA's Space Physics Data Facility at Goddard Space Flight Center. It serves as a central archive for the Heliospheric Science Division.

Use Cases

• Analyze hourly-averaged solar wind plasma parameters across different spacecraft like ACE and Wind to study near-Earth space weather conditions.
• Compare magnetic field measurements from deep space missions like Voyager and Ulysses with near-Earth data from IMP-8 or Geotail to model heliospheric structure.
• Use the multi-source data interfaces to correlate solar wind events observed by different spacecraft such as SOHO and STEREO.

Strengths

• Data aggregated from over 15 distinct spacecraft missions, providing a multi-instrument perspective.
• Includes both near-Earth (e.g., ACE, Wind) and deep space (e.g., Voyager, Pioneer) solar wind measurements for broad spatial coverage.
• Archived and maintained by NASA's Space Physics Data Facility, an authoritative center for heliospheric data.

Limitations

• Specific data volume, row counts, and column definitions are not provided, complicating initial assessment of dataset scale and structure.
• Primary file format is HTML, which is not optimal for direct numerical analysis and may require parsing or conversion.
• The description lacks explicit temporal range, making it unclear over what period the hourly averages are available.
