CARVE Airborne Spectral Radiances for Arctic Carbon Study

2012 to 2015 flight campaigns collected Level 1 spectral radiance data over the Alaskan and Canadian Arctic using a Fourier Transform Spectrometer (FTS). The data, produced for the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE), captures seasonal and inter-annual variability to study atmospheric gas content. This information is key for analyzing changes in Arctic carbon cycling and threats from thawing permafrost.

Use Cases

• Analyzing seasonal trends in atmospheric radiance to model carbon dioxide and methane concentrations.
• Mapping spatial variability of spectral signatures across Alaskan and Canadian Arctic landscapes.
• Investigating inter-annual changes linked to permafrost thaw and carbon reservoir vulnerability.
• Validating satellite-based atmospheric composition measurements with airborne FTS data.

Strengths

• Data covers a multi-year time range from 2012 to 2015, enabling analysis of inter-annual variability.
• Campaigns were conducted from March to November each year, capturing crucial seasonal cycles.
• The dataset is hosted on multiple authoritative platforms (NASA EarthData, Data.gov), indicating recognized importance.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date, reporting both 2015-11-13 and 2026-03 13.
• License is ambiguously listed as 'other-license-specified' or 'None', requiring further verification.
