Active layer thickness and soil temperature data collected in Quttinirpaaq National Park near Tanquary Fiord. The dataset includes annual active layer thickness measurements from a 100-point grid installed in 1999 and 2-hourly temperature readings from sensors installed in 2015. The data is provided by Parks Canada as part of the Circumpolar Active Layer Monitoring program to track climate change effects on permafrost.
Use Cases
- Modeling active layer thickness trends based on annual grid measurements
- Analyzing soil thermal regime based on 2-hourly temperature sensor data
- Studying the impact of climate change on near-surface permafrost based on long-term monitoring
- Correlating ground temperature with active layer thaw depth based on co-located sensor and probe data
Strengths
- Long-term monitoring program with grid measurements starting in 1999
- High temporal resolution with temperature data recorded every 2 hours
- Standardized international monitoring protocol (CALM) for active layer thickness
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
