TIMED GUVI: Global Ultraviolet Airglow Flux Movies at 130.4 nm

Global coverage of far-ultraviolet airglow emissions is provided by the TIMED satellite's GUVI instrument. The dataset contains calibrated, geolocated, and rectified intensity images for the atomic oxygen 130.4 nm wavelength band, formatted as a 14-day movie in north polar projection. This Level 1C data product was created by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyzing temporal variations in upper atmospheric oxygen emissions based on the 14-day movie format
• Mapping global airglow patterns for atmospheric modeling based on the calibrated and geolocated intensity data
• Studying polar region phenomena using the north polar projection of the imagery
• Correlating solar activity with atmospheric response based on far-ultraviolet spectral band measurements

Strengths

• Provides nearly contiguous global coverage with a 3000 km wide ground swath per orbit
• Data is calibrated, geolocated, and rectified (Level 1C processing)
• Covers five specific far-ultraviolet spectral bands, with this file focusing on the 130.4 nm atomic oxygen band

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
