Antarctic all-sky CCD image data from a Sino-Japan collaborative observation at Zhongshan Station, commencing March 1998. The system captures 512x512 pixel, 12-bit images at 557.7nm and 630.0nm auroral wavelengths with a 15-second exposure time. Principal investigators were Prof. Natsuo Sato and Dr. Huigen Yang.
Use Cases
- Analyze auroral intensity variations over time using the 15-second exposure time series.
- Compare spatial patterns of 557.7nm and 630.0nm emission lines across the 512x512 pixel images.
- Correlate auroral activity with other geophysical data using the timestamp metadata from each observation.
- Train image segmentation models to identify auroral structures from the 12-bit monochromatic CCD frames.
Strengths
- Images have a defined spatial resolution of 512x512 pixels.
- Data captures two specific auroral emission wavelengths (557.7nm and 630.0nm).
- Observation commenced in March 1998, providing a long-term baseline.
Limitations
- Specific row count, total image volume, and temporal end date are unknown.
- Data collection method involves manual filter changes, potentially introducing gaps.
- Original recording on DVD RAM disks may present data retrieval challenges.
