| Summary: | <p>Recent observations of near-surface soil temperatures over the circumpolar
Arctic show accelerated warming of permafrost-affected soils. The
availability of a comprehensive near-surface permafrost and active layer
dataset is critical to better understanding climate impacts and to
constraining permafrost thermal conditions and its spatial distribution in
land system models. We compiled a soil temperature dataset from 72 monitoring
stations in Alaska using data collected by the U.S. Geological Survey, the
National Park Service, and the University of Alaska Fairbanks permafrost
monitoring networks. The array of monitoring stations spans a large range of
latitudes from 60.9 to 71.3° N and elevations from near sea level to
∼ 1300 m, comprising tundra and boreal forest regions. This dataset
consists of monthly ground temperatures at depths up to 1 m,
volumetric soil water content, snow depth, and air temperature during
1997–2016. These data have been quality controlled in collection and
processing. Meanwhile, we implemented data harmonization evaluation for the
processed dataset. The final product (PF-AK, v0.1) is available at the Arctic
Data Center (<a href="https://doi.org/10.18739/A2KG55" target="_blank">https://doi.org/10.18739/A2KG55</a>).</p> |
