SOL-1: Space Weather Auxiliary Data from Lagrange 1 Point

Archived daily auxiliary data from the Space Weather Follow On Lagrange 1 (SOL-1) satellite, which launched in April 2025. The collection is archived by the National Oceanic and Atmospheric Administration and includes daily files in NetCDF format. The data was last updated in the repository on April 11, 2026.

Use Cases

• Modeling solar radiation and particle flux based on solar observation data
• Analyzing spacecraft attitude and orbital parameters for mission operations
• Calibrating primary instrument data using auxiliary telemetry streams

Strengths

• Data originates from a dedicated space weather satellite (SOL-1) launched in 2025.
• Archival process includes one standardized daily file in NetCDF format.
• Dataset is maintained by the National Oceanic and Atmospheric Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
