Warm-air entrainment and advection during alpine blowing snow events

Description: This dataset includes 50 Hz sonic anemometry data, 3-Dimensional wind vectors and sonic temperature, used in the publication “Warm-air entrainment and advection during alpine blowing snow events.” doi.org/10.5194/tc-14-2795-2020. The observations were conducted at the Fortress Mountain Snow Laboratory as part of the PhD work of Nikolas Aksamit. Each file begins at midnight at the beginning of the recording day and runs until the end of the experiment, typically close to midnight. The two anemometers were located on the same steel mast above a constant snow cover. The data spans five days from Nov 20 2015 to Mar 3 2016. The depth of snow fluctuated between the days of observation causing the anemometer height above the snow to vary between 20 and 50 cm for the lower anemometer and 120 and 150 cm. The purpose of the study was to connect turbulent structures as identified in these time series with blowing snow transport measured immediately below the mast. No preprocessing of the data has been performed and caution should be taken to avoid measurements that were contaminated by blowing snow particles.
