BOREAS TF-04: Soil CO2 and CH4 Fluxes in Jack Pine Forests

Twenty-four chamber sites measured soil-atmosphere carbon exchange across four distinct forest ages, from mature stands to clear cuts. The BOREAS TF-04 team collected gross and net CO2 flux alongside CH4 flux data over 19 months in the Southern Study Area. This dataset provides a direct comparison of greenhouse gas emissions from soils under different stages of boreal forest development.

Use Cases

• Modeling soil respiration rates based on forest age and type.
• Comparing net ecosystem exchange between mature and regenerating stands.
• Quantifying methane source/sink dynamics in managed boreal landscapes.
• Calibrating remote sensing estimates of soil carbon flux with ground-truth chamber measurements.

Strengths

• Provides data from 24 distinct chamber sites across four forest conditions.
• Covers a 19-month time series from August 1993 to March 1995.
• Includes both gross and net CO2 flux measurements alongside CH4 flux.

Limitations

• Column names and specific data structure are not documented in the provided sources.
• Conflicting metadata: one source lists a last updated date in 2026, while another indicates data collection ended in 1995.
• Exact file sizes and row counts are unknown.
