• Description:
  We present temperature inversion characteristics during fog and nonfog conditions at three east Greenland coastal weather stations during Arctic melt seasons 1980 –2016. For this purpose, we developed a novel automated method to extract fog-top height (FTH) from Integrated Global Radiosonde Archive data, which is applicable to any fog thermodynamic pro file and includes an improved interpolation of saturation between sounding levels. From the analysis of >22,000 melt-season soundings we conclude that inversions occur 85 –95% of the time, are predominantly elevated, and have median depths >200 m. Fog at high-Arctic locations often penetrates the inversion layer, especially in the late melt season, and is commonly several
