The chemical composition and pH of 30 fresh snow samples collected during December 1986 to May 1987 at Gulmarg (34° 03' N, 74° 24' E, 2655 m above mean sea level), a remote place in north India, were studied The snow samples were, by and large, alkaline in nature and were largely influenced by non-marine aerosols. The concentrations of cations (Ca2+, K+ and Mg2+) were more than the anions (SO42- and NO3-). Factor analysis indicated that most of the ionic components were transported into the region during the period of measurements. The transport of ionic components could be attributed to the passage of western disturbances over this region. The comparison of concentrations of anions and cations in the snow samples at Gulmarg with those reported from a few countries in the west revealed that the composition of Gulmarg snow largely differs in the concentrations of cations rather than anions. Among the cations, the concentration of Ca2+ was high at Gulmarg and this could be responsible for buffering the pH of snow in the alkaline range.
