CARVE Airborne Infrared Radiance for Arctic Permafrost Study

Forward Looking Infrared camera radiance counts were collected from a CARVE aircraft over Alaska between April 2013 and November 2015. This data captures surface temperature imagery alongside concurrent atmospheric measurements of carbon dioxide, methane, and ozone. It was produced for the Carbon in Arctic Reservoirs Vulnerability Experiment, with management attributed to ORNL_CLOUD.

Use Cases

• Characterizing land surface temperature over permafrost regions using thermal imagery.
• Correlating surface radiance with in-flight atmospheric gas concentrations (CO2, CH4, O3).
• Analyzing seasonal changes in the Arctic landscape across a multi-year observation period.
• Supporting models of carbon reservoir vulnerability linked to permafrost thaw.

Strengths

• Data collection spans a 2.5-year time range from April 2013 to November 2015, capturing seasonal cycles.
• Provides co-located surface temperature imagery and atmospheric gas measurements from a single aircraft platform.
• 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.
• Conflicting last updated dates exist: one source reports 2026-03-13, another reports 2015-11 -13.
