TIMED GUVI: Ultraviolet Airglow Flux Movies for South Polar Region

14-day movies of ultraviolet airglow flux mapped in a south polar projection. The TIMED satellite's Global Ultraviolet Imager (GUVI) measures far ultraviolet airglow across five spectral bands, including the LBH1 band (1400-1500 Å). This Level 1C Disk Version 3 file provides calibrated, geolocated, and rectified intensities for the LBH1 wavelength band.

Use Cases

• Visualizing temporal changes in ultraviolet airglow based on mapped images by orbit.
• Analyzing spatial patterns of atmospheric emissions based on the south polar projection.
• Studying the intensity of molecular nitrogen Lyman-Birge-Hopfield bands based on the LBH1 wavelength band data.
• Correlating satellite orbit data with ultraviolet flux measurements based on the cross-track scanning spectrograph's 3000 km ground swath.

Strengths

• Data is calibrated, geolocated, and rectified, indicating a processed Level 1C product.
• The instrument provides nearly contiguous global coverage with 15 orbits per day.
• Movies are provided for a 14-day period, offering a temporal sequence.

Limitations

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