TIMED GUVI: Global Ultraviolet Airglow Flux Movies at 130.4 nm

Movies of calibrated, geolocated ultraviolet airglow intensity at 130.4 Ångströms, mapped using a Transverse Mercator projection. The data is produced by the TIMED satellite's GUVI instrument, which provides nearly contiguous global coverage with 15 orbits per day. This Level 1C Disk dataset is provided by the National Aeronautics and Space Administration (NASA).

Use Cases

• Analyzing global patterns of atomic oxygen emissions in the thermosphere based on the 130.4 nm wavelength band.
• Studying temporal variations in airglow intensity across orbits based on the 14-day movie format.
• Mapping geospatial distributions of far-ultraviolet radiation using the calibrated and rectified intensity images.
• Investigating the relationship between solar activity and atmospheric emissions based on the cross-track scanning spectrograph data.

Strengths

• Provides calibrated, geolocated, and rectified intensities for a specific ultraviolet wavelength band (130.4 Ångströms).
• Offers nearly contiguous global coverage from a cross-track scanning instrument with a 3000 km ground swath width.
• Data is presented as a time-series movie, allowing for analysis of orbital and multi-day variations.

Limitations

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