Himalayan snow chemistry: Chemical composition of fresh snow samples from Kashmir valley
نویسنده
چکیده
The present paper deals with variability in snow chemistry of various sites spread in six districts of the Kashmir Himalayan valley, experiencing frequent snow fall during winter ( Dec.Feb). Chemical composition of fresh snow samples shows wide changes in pH (5.8–7.3), dissolved oxygen content (22-26 mg L-1), and total alkalinity (2-3 mg L-1). The levels ( mg L-1) of calcium (13.3– 28 ), magnesium (8-12 ), chloride (15-30), sulphate (2-8), silicate (1-4) and nitrate (1.9-3.9) differed considerably. The study makes a strong plea for in-depth investigations of snow chemistry of littleexplored Himalayan region, useful for assessing the impact of environmental pollution.

Extended abstract Introduction The attention of forefront foreign researchers has focused on glacier circus. Glacial cirque is the most important pattern of glacial erosion. Deep depressions with steep walls, flat floor or low slope, half-bowl shaped (crescent shaped) are created at high altitudes in the mountains margin by the erosion of mountain glacier (Ahmadi, Feiznia, 2012). Th...
متن کاملRetrieval of snow albedo and grain size using reflectance measurements in Himalayan basin
In the present paper, spectral reflectance measurements of Himalayan seasonal snow were carried out and analysed to retrieve the snow albedo and effective grain size. The asymptotic radiative transfer (ART) theory was applied to retrieve the plane and spherical albedo. The retrieved plane albedo was compared with the measured spectral albedo and a good agreement was observed with ±10% differenc...
