This data set includes the PM2.5 mass concentration of atmospheric aerosol particles at Southeast Tibet station, Ali station, mostag station, Everest station and Namuco station (unit: mm) μ g/m3）。 Aerosol PM2.5 fine particles refer to particles with aerodynamic equivalent diameter less than or equal to 2.5 microns in the ambient air. It can be suspended in the air for a long time, which has an important impact on air quality and visibility. The higher its concentration in the air, the more serious the air pollution. The concentration characteristic data of PM2.5 is output at the frequency of obtaining a set of data every 5 minutes, which can realize the analysis of aerosol mass concentration at different time scales such as hour, day and night, season and interannual, which provides the analysis of changes and influencing factors of aerosol mass concentration at different locations in the Qinghai Tibet plateau at different time scales, as well as the evaluation of local air quality, It provides important data support.

Due to the unique lifestyle of residents and single fuel source, the main fuel in the pastoral area of Qinghai Tibet Plateau is dried yak dung. Yak dung is collected in piles or moulded into dung cake, which is stored after air drying. When used for cooking and heating in residences, it is always burned in cast iron stove. The carbonaceous particles released by yak dung burning are almost the only black carbon aerosol emission source in the vast pastoral area besides motor vehicles. This data set was established by measuring the morphology, particle size and element composition of single particles emitted from yak dung combustion in typical pastoral areas of the Qinghai Tibet Plateau. The sampling sites included Dangxiong County in Naqu and Dazi County in Lhasa. The field sampling location were the chimney outlet of residential homes. The particles were collected on the polycarbonate filter membrane and analyzed in the laboratory by means of computer-controlled scanning electron microscope and X-ray energy spectrometer. The environmental single particles emitted from yak dung combustion in pastoral areas include soot aggregates, tar balls, heavy metals containing carbonaceous particles, mineral dust, and soluble salt particles. This data set includes the numer percentages, particle size and their shape factor (aspect ratio, roundness and form factor) of various types of particles with statistical significance, It is not only an effective supplement to the basic data of human activities affecting the atmospheric environment, but also has potential significance for evaluating their optical characteristics, radiation effects, health effects and environmental impact of local source carbonaceous aerosols on the plateau.
