Short summary

The paper facilitates the construction of a satellite-derived 2 m air temperature (T_2m) product for Arctic snow/ice areas. The relationship between skin temperature (T_skin) and T_2m is analysed using weather stations. The main factors influencing the relationship are seasonal variations, wind speed and clouds. A clear-sky bias is estimated to assess the effect of cloud-limited satellite observations. The results are valuable when validating satellite T_skin or estimating T_2m from satellite T_skin.
