U6: Active-Layer Thickness Measurements Near Deadhorse, Alaska

U6 data represents active-layer thickness measurements collected near Deadhorse, Alaska as part of the CALM network. The CALM network is described as the only coordinated and standardized program using standard protocols to observe decadal changes in seasonal thawing and freezing in high-latitude soils. The dataset was last updated by organization SCIOPS on 2010-11-23.

Use Cases

• Modeling permafrost thaw dynamics based on active-layer thickness observations.
• Analyzing long-term trends in seasonal soil freezing and thawing based on standardized decadal observations.
• Calibrating remote sensing or climate models with ground-truth data on active-layer thickness.

Strengths

• Data is part of the only coordinated and standardized program (CALM) for observing these dynamics.
• Measurements follow standard protocols designed for detecting decadal changes.
• Last update timestamp is precisely recorded as 2010-11-23 23:59:59.999000.

Limitations

• Last updated 2010-11-23 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
