Abstract. Seasonal snow covers Arctic lands 6 to 10 months of the year and is therefore an essential element geosphere biosphere. Yet, even most sophisticated physics models are not able simulate fundamental physical properties snowpacks such as density, thermal conductivity specific surface area. The development improved in progress, but testing requires detailed driving validation data for high herb tundra sites, which presently available. We present years ice-wedge polygonal site Canadian Arctic, Qarlikturvik valley on Bylot Island at 73.15∘ N. with no erect vegetation thick permafrost. Detailed soil provided. Driving comprised air temperature, relative humidity, wind speed, shortwave longwave downwelling radiation, atmospheric pressure, precipitation. Validation include time series depth, upwelling temperature profiles, water content profiles five depths, three heights, cm depth.
