The Himalayas has one of the largest concentrations of glaciers and permanent snowfields outside the polar region. Snow and glacier melt forms an important source for many rivers originating in the Himalayas. Numerous studies suggest that global warming has started affecting snow melt and stream run-off in the Himalayan region. Monitoring the snow-cover changes is therefore essential to assess the future hydrologic cycle. Snowline altitude is an important parameter to assess future changes in snow cover.
