ISEE 1 Solar Wind Analyzer: 24-Second Plasma Parameters from 1977-1983

24-second and 48-second solar wind ion plasma parameters were collected by the ISEE 1 spacecraft during solar wind seasons from approximately July to January between 1977 and 1983. The data includes ion density, flow speed, flow angles, temperatures, and alpha-to-proton density ratio from LANL's Cross-Fan Solar Wind Ion Experiment. It is provided by the National Aeronautics and Space Administration and is accessible via CDAWeb and FTP.

Use Cases

• Modeling solar wind propagation based on ion density and flow speed parameters.
• Analyzing plasma temperature anisotropy based on perpendicular and parallel temperature measurements.
• Studying solar wind composition based on the alpha-to-proton density ratio.
• Investigating seasonal solar wind variations based on data collected during specific annual periods.

Strengths

• Data covers a specific 6-year time range from 1977 to 1983.
• Parameters include multiple plasma characteristics such as density, speed, angles, and temperatures.
• Data is from a recognized NASA mission and instrument suite.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
