Arctic Treeline Spruce Growth and Environmental Measurements, 2016-2019

Arctic treeline sites in Alaska and Canada provide in situ measurements of radial growth for 60 white and black spruce trees, alongside environmental variables. Data collection spanned from June 2016 to September 2019, with high-frequency sampling intervals of 5 to 20 minutes. This dataset was produced by ORNL_CLOUD to study environmental influences on tree growth dynamics.

Use Cases

• Analyzing correlations between radial tree growth and concurrent air temperature or soil temperature.
• Modeling the impact of soil volumetric water content and solar irradiance on spruce growth rates.
• Comparing seasonal growth patterns of Picea glauca and Picea mariana across two Arctic sites.
• Investigating the relationship between atmospheric pressure, relative humidity, and short-term tree stem fluctuations.

Strengths

• Includes simultaneous measurements from 60 individual trees (36 in AK, 24 in NWT) over multiple years.
• Environmental variables (air temp, soil temp, VWC, etc.) are recorded at a consistent 5-minute sampling interval.
• Data covers a multi-year time range from 2016 to 2019 at two distinct geographic locations.

Limitations

• Dendrometer (radial growth) data is incomplete for the full period, covering only 2016-2017 within this specific dataset.
• Sources conflict on the last updated date (2019-09-13 vs. 2026-03 13), suggesting potential metadata inconsistency.
• Complete column names and exact row counts are not provided by any source platform.
