CARVE Airborne Arctic Greenhouse Gas Concentrations 2012-2015

Merged and gap-filled atmospheric concentrations of CO2, CH4, CO, O3, and H2O from airborne campaigns over Alaska and the Canadian Arctic. Data was collected at 5-second intervals during flights from 2012 to 2015, spanning March to November each year to capture seasonal cycles. The dataset is a product of the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) and is hosted by ORNL_CLOUD.

Use Cases

• Analyzing correlations between latitude, longitude, altitude and concentrations of key greenhouse gases like methane and carbon dioxide.
• Investigating seasonal and inter-annual variability in atmospheric gas content across the Arctic from March to November.
• Modeling the spatial distribution of carbon monoxide and ozone to understand atmospheric chemistry and pollution transport.
• Studying water vapor indicators alongside trace gases to assess atmospheric conditions and measurement quality.
• Validating satellite-derived estimates of Arctic carbon fluxes using precise, high-frequency airborne in-situ measurements.

Strengths

• Provides high-temporal-resolution measurements recorded at 5-second intervals throughout each flight.
• Covers multiple years (2012-2015) and seasons (March-November) to enable analysis of both seasonal and inter-annual variability.
• Data is merged and gap-filled from two cavity ring-down spectrometers, improving continuity.

Limitations

• Specific row counts, dataset size, and a complete column list are not provided by any source.
• Conflicting 'last updated' dates exist between platforms (2014-11-09 and 2026-03 13), creating uncertainty about metadata freshness.
