Turbulent flux measurements of carbon dioxide and methane from the 10m tower at the MetCity ice camp site during the 2019-2020 MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition

These are the turbulent flux results for CO2 and CH4 measured from the 10m tower located at the MetCity ice camp site during the MOSAiC expedition, from October 2019 to October 2020. Instrumentation on the MetCity tower included: 3-D ultrasonic anemometers (Metek model uSonic-Cage MP) at 2, 6, and 10m heights; a Licor 7500DS open path water vapor sensor at the 2m level; bulk temperature and relative humidity at 2, 6, and 10m levels, and surface pressure, among other things. Results are hourly means, filtered for optimal conditions. A full description of the flux calculations, filtering and averaging procedures, and variable definitions is provided in an associated readme document.
