TIMED GUVI: Global Ultraviolet Airglow Movies at 1356 Å

Global satellite imagery of Earth's ultraviolet airglow at the 1356 Å oxygen emission line. The data consists of calibrated, geolocated, and rectified intensity images from the TIMED satellite's GUVI instrument, presented as a 14-day movie in Mercator projection. This Level 1C dataset was produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyzing global patterns of atomic oxygen emissions based on the 1356 Å wavelength band
• Studying ionospheric dynamics and space weather effects based on the 14-day movie format of airglow intensity
• Developing geospatial models of atmospheric phenomena based on the Mercator-projected, calibrated imagery
• Validating atmospheric models using the cross-track scanning spectrograph's 3000 km swath width for near-contiguous global coverage

Strengths

• Data is calibrated, geolocated, and rectified, as stated in the description
• Provides near-contiguous global coverage with a 3000 km ground swath width from 15 orbits per day
• Focuses on a specific, scientifically relevant wavelength band (1356 Å atomic oxygen)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect temporal or instrumental bias inherent to the single satellite source
