CARVE Airborne Greenhouse Gas Concentrations in the Arctic (2012-2015)

Atmospheric concentrations of carbon dioxide, methane, carbon monoxide, and water vapor were collected via airborne campaigns over Alaska and the Canadian Arctic. The data were gathered in situ using a cavity ring-down spectrometer at 2-second intervals during flights from 2012 to 2015, covering seasonal cycles from March to November. This dataset was produced by NASA for the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE).

Use Cases

• Analyzing seasonal and inter-annual variability of Arctic CO2 and CH4 concentrations using the 2-second time-series data.
• Mapping the spatial distribution of greenhouse gas plumes by correlating gas concentrations with aircraft latitude and longitude.
• Investigating sources of carbon monoxide as a tracer for combustion or oxidation processes in the Arctic atmosphere.
• Studying correlations between water vapor and other greenhouse gases to understand atmospheric transport and mixing.

Strengths

• High temporal resolution data provided at 2-second intervals throughout each flight.
• Covers multiple years (2012-2015) and seasons (March-November) for investigating variability.
• Measures four key atmospheric components (CO2, CH4, CO, H2O) simultaneously using a cavity ring-down spectrometer.

Limitations

• Exact row count, file size, and complete column names are not specified across any platform.
• Sources conflict on the last updated date, with one listing 2014 and another listing 2026.
• The license is specified only as 'other-license-specified', requiring further investigation for reuse.
