摘要
The Arctic,the Antarctic as well as the Qinghai-Tibet Plateau(QTP)are cold regions on Earth where snow and ice dominate the local environment and impact the global climate via several strong feedback mechanisms.The observations and information service for those cold regions are vital for the societal benefits,and support from the science to policy making(Qiu et al.2016).Earth cold regions exhibit strong sensitivity to global climate change and are thus some of the most fragile regions in terms of global ecology(Pulliainen et al.2017).Due to these inherent similarities,the Qinghai-Tibet Plateau area has been termed as the‘Third Pole’,which is experiencing profound environmental changes.
