Data sets of ground air exchange fluxes and vertical gradients of air pollutants at Namco station (2019) and Southeast Tibet station (2021)

This data is obtained through observation at Namucuo multi cycle comprehensive observation and research station of Chinese Academy of Sciences (2019) and Tibetan southeast alpine environment comprehensive observation and research station of Chinese Academy of Sciences (2021), including the earth atmosphere exchange flux or vertical gradient of species such as O3, NOx, HONO, H2O and HCHO. The time range is from April 28, 2019 to July 10, 2019 (Namuco station) and from May 2, 2021 to May 13, 2021 (Southeast Tibet station). The data consists of five documents. Documents 1-4 are the flux data and H2O vertical gradient, HONO vertical gradient and NO2 vertical gradient observed at Namuco station in 2019. Document 5 is the flux data observed at Southeast Tibet station in 2021. During the monitoring period, data was missing due to instrument status problems. This data has broad application prospects and can serve graduate students and scientists with backgrounds such as atmospheric science, climatology, and ecology.

Data set of atmospheric pollutant concentration in Lhasa and Nyingchi, Tibet (May-June, September-October, 2021)

The data set contains the on-line monitoring data of air pollutants in Lhasa and Nyingchi, Tibet Autonomous Region. The sample collection time is from May to June and from September to October 2021. The data sampling points were located in Nagin campus of Tibet University in Lhasa, Tibet and Tibet agriculture and Animal Husbandry College in Nyingchi, Tibet. We set up a temporary environmental pollution monitoring station. Thermo Gas Analyzer, GRIMM Portable Aerosol Spectrometer, FMPS, AE-33 were used to monitor the concentration of air pollutants such as ozone (O3), nitrogen dioxide (NO2), particulate matter (PM), ultra-fine particulate matter (UFP) and black carbon (BC) online, Vantage Vue weather station was used to monitor temperature, humidity, air pressure and other meteorological data online. The abnormal values during the operation of the instrument have been deleted, and the time resolution of the data after calibration and cleaning is 1 hour. This data provides basic data for the comprehensive evaluation of the effects of air pollution on population health in Tibet.

Atmospheric oxidizability data set of Namco station (2019)

1) Data content: the observation data of atmospheric oxidation related parameters in Namuco from April to July 2019, including O3, H2O, CO2, NO2, VOCs, wind direction and wind speed. The coordinates of the observation points are 90.96 ° e, 30.77 ° n, 4730m above sea level, and the underlying surface is alpine grassland. (2) Data source and processing method: the original observation data shall be processed and quality controlled by special personnel according to the observation records. (3) Data quality description: due to the problem of instrument status, the data is missing and discontinuous in some periods. (4) Application prospect of data: the data can be applied to plateau atmospheric chemical analysis and other fields.
