Vertical profiles of electric potential near surface were observed during blowing snow at the top of Mt. Teine, 1959, 60 and 61. By the use of the data, vertical distributions of layer charge or space charge were calculated. These charges are supposed to be carried on the blowing snow particles or ions. The vertical distribution showed that a layer of positive charge and another layer of negative charge existed just near the surface and around 1 m above the surface respectively. This result seems to be favourable to explain the confused discrepancy among the results obtained hitherto by Simpson, Yoshida and Ôta.
