Temperature measurements from 16 nodes of a 100x100 meter grid at the Crater Lake CALM site on Deception Island, Antarctica, recorded at about 50 cm depth. Data acquisition began in 2006, with readings taken from 1 to 4 hours. The PERMATHERMAL monitoring network is led by Dr. Miguel Ángel de Pablo of Universidad de Alcalá.
Use Cases
- Analyze seasonal temperature variations at 50 cm depth across the 16-node grid.
- Model permafrost thermal regime using time-series data collected at 1-4 hour intervals since 2006.
- Correlate ground temperature data from PT stations with active layer thickness measurements from the CALM grid.
- Study long-term permafrost temperature trends at the Deception Island monitoring site.
Strengths
- Time-series data collected at 1-4 hour intervals since 2006, providing high temporal resolution.
- Measurements from 16 spatially distributed nodes within a standardized 100x100 m CALM grid.
- Part of a long-term monitoring network (PERMATHERMAL) following GCOS principles.
Limitations
- Limited spatial coverage to a single 100x100 m grid at one Antarctic island site.
- Unknown sample size and data completeness for the time series.
- Depth of measurement is fixed at approximately 50 cm, lacking a vertical temperature profile.
