The Tibetan Plateau(TP),widely known as the Third Pole,is the highest and largest plateau on *** TP not only plays an important role in influencing the atmospheric circulation,surface energy budget,ecology,weather,and climate but also acts as the Asian Water Tower by holding the largest ice mass outside the polar regions to supply fresh water to over 1.4 billion people downstream in Asia(Qin et al.,2006).The observed historical warming and projected future warming over the TP are much stronger than the corresponding global average(Wang et al.,2008).Glaciers on the TP have been retreating extensively in recent decades,driven by atmospheric warming and circulation changes associated with increasing concentrations of greenhouse gases and aerosols in the atmosphere,light-absorbing particles(e.g.,black carbon,dust)on snow,and other factors(Duan et al.,2012;Qian et al.,2011;zhao et al.,2020).In addition,due to the thermal and dynam-ical effects of the TP,as well as its proximity to the stratosphere,unique atmospheric boundary layer structures often develop over the TP and in the surrounding areas,which have important impacts on local weather,climate,and mixing and transport of atmospheric constituents(zhao et al.,2020).The TP is considered a natural laboratory to study multi-sphere inter-actions.A systematic mechanistic understanding of the atmospheric chemical and microphysical processes,climate change,cryospheric variability,and the subsequent environmental impacts is particularly important in the context of the unpreceden-ted warming over the TP(Yao et al.,2019).
