CARVE Tower Atmospheric Gas Concentrations in Alaska 2011-2015

Alaska's CARVE flux tower in Fox provides continuous in situ atmospheric measurements from October 2011 to May 2015. This dataset includes dry air mole fractions for methane, carbon dioxide, carbon monoxide, and water vapor, plus temperature, wind velocity, and pressure data collected from three sampling heights. It was generated for the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) using a Picarro cavity ring-down spectrometer.

Use Cases

• Analyzing vertical gradients of CH4, CO2, and CO concentrations from measurements at 4.9 m, 17.1 m, and 31.7 m heights.
• Investigating correlations between greenhouse gas mole fractions and concurrent meteorological variables like ambient temperature and wind velocity.
• Studying seasonal and interannual variability of Arctic atmospheric composition over a multi-year period (2011-2015).
• Validating remote sensing data or model outputs for carbon cycle processes in the Arctic region.

Strengths

• Provides continuous, in situ measurements from a fixed tower location, ensuring consistent temporal coverage.
• Includes data for three key greenhouse gases (CH4, CO2, CO) plus water vapor and meteorological variables, offering a multi-parameter view.
• Samples air from three distinct heights (4.9 m, 17.1 m, 31.7 m), enabling analysis of vertical atmospheric gradients.

Limitations

• Specific column names, row counts, and total dataset size are not provided by any source.
• Sources conflict on the last updated date, listing both 2014-12-31 and 2026-03-13.
