SESAME FPI: Antarctic Atmospheric Horizontal Velocities, April–September

April to September data in 30-minute resolution from the SESAME Fabry-Perot Interferometer. The dataset contains horizontal velocity components derived from line-of-sight measurements at 30-degree elevation, with an indicator for emission wavelength (558 or 630 nm). It was produced by the National Aeronautics and Space Administration and is referenced in peer-reviewed publications from 1985 and 1995.

Use Cases

• Modeling thermospheric wind patterns based on horizontal velocity data.
• Analyzing seasonal ionospheric variations based on the April to September time range.
• Correlating atmospheric emissions based on the 558 nm or 630 nm wavelength indicator.
• Validating satellite data with ground-based Antarctic measurements.

Strengths

• Data has a defined 30-minute temporal resolution.
• Covers a specific seasonal period from April to September.
• Includes a clear emission wavelength indicator (558 or 630 nm).

Limitations

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