1) Data content: this data is the carbon and nitrogen isotope data generated from the study of human bone collagen in Jiangxi tomb site, Jiyi Town, Wuding County, Yunnan Province. It can be used to preliminarily analyze the human diet structure of Jiangxi tomb site, Wuding county and reveal the life and career patterns of local ancient people. 2) Data source and processing method: provided by the environmental archaeology team of Lanzhou University and obtained by acid alkali acid experimental process and gas stable isotope mass spectrometer (Finnigan Deltaplus isotope ratio mass spectrometer). 3) Data quality: 9.38kb. 4) Data application achievements and prospects: the data are used to explore the research potential of stable isotopes of human bones at sites in revealing the development process of prehistoric career model in Yunnan.
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. This data is an update of the published data set of PM2.5 concentration of aerosol particles at different stations on the Qinghai Tibet Plateau (2018 and 2019).
