Associate Prof. Xiaoping Wang and her colleagues succeeded in setting up multi-functional automatic samplers at ITPCAS’s field observation and research stations at Ngari, Mt Qomolangma, and Nyingchi, as well at Yulong Snow Mountain Observation Station for Glaciers and Environment of the CARRERI. Thanks to the joint support of the NSFC and CAS Key Laboratory of Tibetan Environmental Changes and Land Surface Processes (TEL), these widely distributed samplers would collect air samples and atmospheric aresols at large capacity, conducive to the acquisition of temporal series of pollutant’s density and spatial distribution of various pollutants.

With long-term observation using these samplers, scientists believed that they can obtain POPs records of high resolution, so as to monitor the major pollutants within carbonaceous aresols emitted from the South Asian sub-continent, and to help answer the question of the influence of atmosphere brown cloud on eco-environment on the Tibetan Plateau.
