Daily raw images from time-lapse cameras monitoring the Crater Lake CALM site on Deception Island, Antarctica, since 2008. The data is part of the PERMATHERMAL network, which tracks frozen ground conditions and is led by Dr. Miguel Ángel de Pablo of Universidad de Alcalá. The network itself began in 2000 and includes multiple monitoring stations across two Antarctic islands.
Use Cases
- Analyze seasonal snow cover duration and melt patterns from daily image sequences.
- Correlate visual ground surface conditions from imagery with active layer thickness measurements from the 100x100m CALM grid.
- Track long-term landscape changes and periglacial feature activity at the Crater Lake site over the 15+ year record.
- Validate and calibrate thermal models using visual surface data alongside temperature and snow depth sensor readings.
Strengths
- Daily acquisition frequency provides high temporal resolution for seasonal processes.
- Imagery record spans over 15 years, starting in 2008, enabling long-term trend analysis.
- Data is integrated within a wider monitoring network with complementary ground temperature and active layer measurements.
Limitations
- The raw, unprocessed image format requires significant preprocessing for quantitative analysis.
- Specific sample size (row count) and image resolution are unknown.
- Geographic coverage is limited to specific sites on Deception and Livingston Islands.
