Estimated range of black carbon dry deposition and the related snow albedo reduction over Himalayan glaciers during dry pre-monsoon periods

► Black carbon emission is significant over Indo-Gangetic Plain. ► We estimated possible wider range of black carbon dry deposition over the southern Himalayas. ► Its impact on snow albedo reductions over Himalayan glaciers was also estimated. ► Surface wind and roughness affect the deposition amount and snow albedo reduction. ► Surface parameterization in transport model is important for their accurate estimate.
