ABoVE: Soil Temperature Profiles from USArray Stations in Alaska and Canada, 2016-2019

Alaska, USA, and Yukon, Canada, are the geographic scope for this dataset of soil temperature profile measurements from 16 monitoring sites. The National Aeronautics and Space Administration collected measurements from 2016 to 2019 at varying depths up to 1.5 meters, with hourly or 6-hourly frequency. These data complement existing networks to characterize ground temperatures and permafrost conditions.

Use Cases

• Model permafrost thaw and stability based on multi-depth soil temperature time series.
• Analyze seasonal and interannual ground temperature variability across different Alaskan sites.
• Validate and calibrate remote sensing or land surface models using in-situ temperature profile data.
• Study the relationship between seismic station locations and subsurface thermal conditions.

Strengths

• Measurements span up to 1.5 meters depth, providing a vertical soil temperature profile.
• Data collected from 16 distinct sites across Alaska and Canada over multiple years (2016-2019).
• Six sites are collocated with USArray seismic stations, enabling potential multi-sensor analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Measurement frequency and date ranges vary per site, complicating uniform temporal analysis.
