An attempt has been made to compute the thickness of morning fog-layers which formed over Calcutta Airport on different occasions during the period 1973-77. According to their thermal and moisture structure, the fog-layers have been grouped into four types and their characteristic features have been presented. The fog-layers could be as shallow as 20 m and as deep as 1000 m. It appears that varying degrees of turbulence in the fog-layers have a bearing to their vertical extent.
