Hourly temperatures and clinometry data have been acquired since 2023 at selected sites of the Limnopolar Lake CALM grid on Livingston Island, Antarctica. The PERMATHERMAL monitoring network, started in 2000 and led by Dr. Miguel Ángel de Pablo of Universidad de Alcalá, aims to track seasonal and permanent frozen ground following GCOS principles. Data collection includes active layer thickness measurements and permafrost temperature from distributed stations.
Use Cases
- Model active layer thickness dynamics using hourly temperature time-series from different ground depths.
- Analyze ground subsidence and heave patterns from clinometry data correlated with seasonal temperature cycles.
- Validate permafrost thermal models with continuous temperature records from the PT station network.
- Study interannual variability in frozen ground conditions using data from the network operational since 2000.
Strengths
- Hourly temporal resolution for temperature and deformation measurements provides detailed diurnal cycle data.
- Network has been operational and expanding since 2000, offering potential for long-term trend analysis.
- Data collection follows GCOS (Global Climate Observing System) principles, ensuring standardized methodology.
Limitations
- Specific row count, column details, and sample data are unavailable, limiting immediate assessment of dataset scale.
- Geographic coverage is limited to specific sites on Livingston and Deception Islands, Antarctica.
