GUVI: Global Ultraviolet Airglow Flux Movies in South Polar Projection

TIMED Global Ultraviolet Imager (GUVI) measures far ultraviolet airglow in five spectral bands. This Level 1C Disk file provides calibrated, geolocated, and rectified intensities for the atomic oxygen OI band at 1356 Å wavelength. The data is presented as a movie of mapped images using a south polar projection.

Use Cases

• Analyze atomic oxygen emissions in the upper atmosphere based on the 1356 Å wavelength band
• Study global airglow patterns based on the cross-track scanning spectrograph's 3000 km ground swath
• Visualize atmospheric dynamics in the southern hemisphere based on the south polar projection
• Calibrate satellite sensor data based on the Level 1C calibrated and geolocated intensities

Strengths

• Provides calibrated and geolocated intensities for a specific ultraviolet wavelength band
• Offers nearly contiguous global coverage from 15 orbits per day
• Data is presented as a movie, facilitating temporal analysis of airglow flux

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 geographic bias inherent to the south polar projection
