Alaskan Soil Temperature and Moisture at Burned and Unburned Sites

ABoVE provides soil temperature and volumetric water content measurements at 15 cm depth from 12 boreal and tundra sites across Alaska. The dataset contains hourly data from HOBO sensors for the period August 2016 to September 2023, collected by ORNL_CLOUD. Measurements were taken at sites with associated CO2 efflux and thaw depth data.

Use Cases

• Modeling soil temperature dynamics at 15 cm depth across 12 Alaskan sites from 2016-2023.
• Analyzing volumetric water content (VWC) variations between burned and unburned boreal and tundra locations.
• Correlating soil moisture sensor data with site-specific laboratory calibration curves for seven sites.
• Integrating soil temperature and VWC time-series with co-located CO2 efflux and thaw depth measurements.

Strengths

• Data spans over 7 years, from August 2016 to September 2023.
• Measurements collected from 12 distinct sites across Alaska.
• Hourly temporal resolution for soil temperature and VWC.

Limitations

• Data coverage varies by site and is not uniformly complete across the time range.
• Site-specific sensor calibration curves are only available for 7 of the 12 sites.
• Unknown total row count and dataset size.
