TIMED GUVI: Ultraviolet Airglow Flux Movies in North Polar Projection

TIMED Global Ultraviolet Imager (GUVI) measures far ultraviolet airglow in five spectral bands. This Level 1C Disk Version 3 file provides calibrated, geolocated, and rectified intensities for the LBH1 wavelength band (1400-1500 Å). The dataset is a movie of mapped images of log intensities by orbit using a north polar projection.

Use Cases

• Visualizing atmospheric airglow patterns based on ultraviolet intensity movies
• Analyzing global coverage of ultraviolet emissions based on a 3000 km ground swath
• Studying molecular nitrogen LBH band emissions based on the LBH1 wavelength band data

Strengths

• Data is calibrated, geolocated, and rectified
• Provides nearly contiguous global coverage with 15 orbits per day
• Images a ground swath of 3000 km width

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
