TIMED GUVI: Global Ultraviolet Airglow Flux Movies at LBH2 Wavelength

A series of 14-day movies showing log intensities of far-ultraviolet airglow from the TIMED satellite's GUVI instrument. The data provides calibrated, geolocated, and rectified intensities for the LBH2 wavelength band (1650-1800 Å) in a transverse Mercator projection, offering nearly contiguous global coverage with 15 orbits per day. This Level 1C Disk Version 3 file was produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Visualizing global airglow patterns based on the mapped log intensity images
• Analyzing temporal variations in far-ultraviolet emissions based on the 14-day movie format
• Studying atmospheric composition and dynamics based on the LBH2 (1650-1800 Å) spectral band data
• Correlating satellite observations with ground-based measurements based on the geolocated and rectified intensities

Strengths

• Data is calibrated, geolocated, and rectified, indicating a processed Level 1C product
• Provides nearly contiguous global coverage from a cross-track scanning spectrograph with a 3000 km swath width
• Offers a temporal sequence via a 14-day movie format, allowing for pattern observation over time

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for quantitative analysis
• Data files are in BIN and PDF formats, which may require specialized tools for processing
