TIMED GUVI: South Polar Ultraviolet Airglow Flux Movies at 130.4 nm

TIMED satellite GUVI instrument movies showing far ultraviolet airglow intensities at the 130.4 nm oxygen wavelength band. The data is calibrated, geolocated, and rectified, providing nearly contiguous global coverage with 15 orbits per day. This Level 1C Disk Version 3 file from NASA presents the log intensities in a south polar projection.

Use Cases

• Analyzing spatial and temporal variations in upper atmospheric oxygen emissions based on the calibrated airglow intensities.
• Studying global coverage patterns of far ultraviolet phenomena based on the 3000 km ground swath and 15 orbits per day.
• Creating visualizations of polar region atmospheric dynamics based on the south polar projection and mapped image sequences.

Strengths

• Data is calibrated, geolocated, and rectified, indicating a processed Level 1C product.
• Provides a wide 3000 km ground swath for nearly contiguous global coverage.
• Produced by NASA, an authoritative space science organization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data is provided in BIN and PDF formats, which may require specialized tools for analysis.
