11 Aims and Tasks Characterize the chemical composition and levels of atmospheric pollutants, depict their spatial and seasonal variation over the HTP. Identify the sources of atmospheric pollutants and reveal the transport pathway and mechanisms of trans-boundary atmospheric pollution to the HTP. Investigate the role of atmospheric pollutants (deposited as LAIs) in the melting of glacier and snow cover and further quantify the contribution of LAIs to the glacier and snowpack melting. Determine the fate of environment-relevant pollutants within glacier and snowpack and their scavenging process during snow/ice melting. Assess the impact of atmospheric pollution on the cryospheric changes over the HTP
