CARVE Atmospheric Gas Concentrations from Alaska Flux Tower

CARVE L2 Atmospheric Gas Concentrations provide mole fractions of carbon dioxide, methane, carbon monoxide, molecular hydrogen, nitrous oxide, and sulfur hexafluoride from a tower in Fox, Alaska. Data were derived from laboratory analysis of whole air flask samples collected multiple times per month from January 2012, as part of the Carbon in Arctic Reservoirs Vulnerability Experiment. The measurements are produced by the NOAA Earth System Research Laboratory Global Monitoring Division.

Use Cases

• Analyzing seasonal and interannual trends in Arctic greenhouse gas concentrations (CO2, CH4).
• Investigating correlations between different trace gas species (e.g., CO, H2, N2O, SF6) in a permafrost region.
• Validating and improving atmospheric transport models for high-latitude carbon cycle studies.
• Assessing the impact of permafrost thaw on atmospheric chemistry by establishing a multi-year baseline.

Strengths

• Provides multi-species atmospheric trace gas data crucial for understanding Arctic carbon cycling.
• Samples are analyzed by the authoritative NOAA/ESRL Global Monitoring Division using their reference network protocols.
• Offers a multi-year time series with regular sampling (multiple times per month) since January 2012.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date, reporting both 2015-12-05 and 2026-03-13.
• The license is noted as 'other-license-specified', requiring users to investigate specific terms.
