TIMED GUVI: Global Ultraviolet Airglow Flux Movies in Mercator Projection

GUVI measures far ultraviolet airglow in five spectral bands, including the LBH1 band from 1400-1500 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 dataset from NASA provides calibrated, geolocated, and rectified intensities for the LBH1 band, formatted as movies of log intensities using a Transverse Mercator projection.

Use Cases

• Analyzing global patterns of far ultraviolet airglow based on calibrated LBH1 band intensities.
• Studying atmospheric composition and dynamics based on spectral band measurements across a 3000 km swath.
• Creating visualizations of orbital data for time-series analysis based on the 14-day movie format.
• Investigating spatial correlations in airglow phenomena using geolocated and rectified image data.

Strengths

• Data is calibrated, geolocated, and rectified, indicating a processed Level 1C product.
• Provides nearly contiguous global coverage from a 3000 km wide imaging swath.
• Includes data from five specific ultraviolet spectral bands, including the LBH1 band.

Limitations

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