Livingston Island in Antarctica provides raw, hourly soil moisture data at different depths from multiple PT monitoring stations. The PERMATHERMAL network, led by Dr. Miguel Ángel de Pablo of Universidad de Alcalá, has collected this data since 2023 as part of a broader permafrost monitoring effort started in 2000.
Use Cases
- Model active layer thickness dynamics using time-series soil moisture and temperature data from different sensor depths.
- Analyze seasonal freeze-thaw cycles by correlating hourly soil moisture readings with air and surface temperature measurements.
- Study spatial variability in ground thermal regimes by comparing data from stations at Collado Ramos, Sofía, and Limnopolar Lake.
- Investigate the impact of snow depth on soil moisture retention using concurrent snow depth sensor data from PT stations.
Strengths
- Hourly temporal resolution provides detailed diurnal and seasonal cycle data.
- Data collected from multiple stations (CR, SO, LL) allows for spatial comparison.
- Network follows GCOS principles, ensuring standardized monitoring practices.
- Part of a long-term monitoring effort with network roots dating to 2000.
Limitations
- The dataset is described as raw and unprocessed, which may require significant quality control.
- Specific sample size, row count, and data completeness metrics are unknown.
- Geographic scope is limited to two specific peninsulas on Livingston Island.
