TIMED GUVI: Ultraviolet Airglow Flux Movies for South Polar Region

GUVI measures far ultraviolet airglow in five spectral bands, including the LBH2 band at 1650-1800 Å. The cross-track scanning spectrograph images a ground swath of 3000 km width, providing nearly contiguous global coverage with 15 orbits per day. This Level 1C Disk file from NASA provides calibrated, geolocated, and rectified intensities for the LBH2 wavelength band as a movie using a south polar projection.

Use Cases

• Visualizing temporal changes in ultraviolet airglow intensity based on mapped images by orbit
• Analyzing spatial patterns of atmospheric emissions in the southern polar region based on the south polar projection
• Studying global coverage of far ultraviolet phenomena based on the 3000 km swath width and 15 orbits per day

Strengths

• Data is calibrated, geolocated, and rectified, indicating processed Level 1C data
• Instrument provides a 3000 km wide ground swath for nearly contiguous global coverage
• Data is presented as a movie, likely facilitating temporal analysis

Limitations

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