BOREAS TGB-01 SF6 Chamber Flux Data: NSA

Chamber flux measurements of sulfur hexafluoride (SF6) were collected at the Boreal Ecosystem Atmosphere Study (BOREAS) Northern Study Area during the summer of 1994. The data capture trace gas exchange between the atmosphere and boreal soils at Old Jack Pine and Young Jack Pine sites. Measurements were taken approximately weekly from dark chambers between 16-May and 13-Sep-1994 and analyzed at an on-site lab.

Use Cases

• Quantifying soil-atmosphere SF6 flux rates in boreal pine ecosystems.
• Modeling trace gas dynamics based on time-series measurements from dark chambers.
• Comparing gas exchange between mature (Old Jack Pine) and regenerating (Young Jack Pine) forest stands.
• Validating soil gas transport models for sulfur compounds in northern latitudes.

Strengths

• Data collection is temporally bounded and specific, covering the period from 16-May through 13-Sep-1994.
• Measurements are site-specific, taken at the well-documented BOREAS NSA Old Jack Pine and Young Jack Pine sites.
• The dataset is cross-platform, appearing on both Data.gov and NASA EarthData, indicating established provenance.

Limitations

• Critical metadata is missing, including column names, row counts, and file sizes.
• Conflicting 'last updated' dates exist between platforms (1994 vs. 2026), creating uncertainty about data currency.
• The license is ambiguously listed as 'other-license-specified' without further detail.
