TIMED GUVI: Global Ultraviolet Airglow Flux Movies at 1356 Å

GUVI's cross-track scanning spectrograph images a 3000 km wide ground swath, 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 atomic oxygen OI band at 1356 Å. The data is presented as a movie of mapped images using a north polar projection.

Use Cases

• Analyze temporal patterns of atomic oxygen airglow based on the 14-day movie format
• Study global atmospheric phenomena based on the nearly contiguous global coverage from 15 orbits per day
• Map ultraviolet intensity distributions based on the calibrated and geolocated north polar projection images
• Correlate airglow flux with other atmospheric data based on the specific 1356 Å wavelength band

Strengths

• Data is calibrated, geolocated, and rectified, indicating a processed Level 1C product
• Provides nearly contiguous global coverage from a 3000 km wide ground swath
• Specific wavelength band (1356 Å) for atomic oxygen OI is targeted

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 north polar projection
