Abstract

These data were obtained in an ice-wedge polygonal site in the Canadian high Arctic, in Qarlikturvik valley on Bylot Island at 73.15°N. The site is on herb tundra with no erect vegetation. One important intended use for these data is to drive and test snow physics models and land surface models under high Arctic conditions. Driving data are comprised of air temperature and relative and specific humidity, wind speed, short wave and long wave downwelling radiation, atmospheric pressure and precipitation. Validation data include time series of snow depth, shortwave upwelling radiation, surface temperature, snow temperature profiles, soil temperature and water content profiles, snow thermal conductivity at three heights and soil thermal conductivity at 10 cm depth. Field campaigns in mid-May provided vertical profiles of snow density and specific surface area in the polygon of interest and at other spots in the valley, named Wet0, TUNDRA, Pit3, PLaine 1&2 and Bombe, with coordinates in the associated ESSD paper. These data sets were first uploaded in February 2021 and included monitoring data from 11 July 2013 to 25 June 2019, i.e. 6 years of data. Field data were obtained in 2014, 2015, 2017, 2018 and 2019. Data files will be updated as more years of data become available.
