Description
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.
