西藏拉萨、林芝地区大气污染物浓度数据集（2021年5-6月、9-10月）

数据集包含西藏自治区拉萨市和林芝市大气污染物在线监测数据。样品采集时间为2021年5-6月、9-10月。 数据采样点位于西藏拉萨市西藏大学纳金校区和西藏林芝市西藏农牧学院。搭建临时环境污染监测站点，使用Thermo气体分析仪、GRIMM 11-D便携式气溶胶粒径谱仪、FMPS粒径谱仪、AE-33黑碳检测仪等仪器，在线监测臭氧（O3）、二氧化氮（NO2）、颗粒物（PM）、超细颗粒物（UFP）、黑碳（BC）等大气污染物浓度，使用Vantage Vue无线自动气象站在线监测温度、湿度、气压等气象数据。已删除仪器运行过程中的异常值，并进行标定。清洗后的数据时间分辨率为1小时。 本数据为综合评估大气污染对西藏地区人群健康效应提供了基础数据。This dataset contains online monitoring data of atmospheric pollutants collected in Lhasa and Nyingchi, Tibet Autonomous Region. The sampling period was May–June and September–October 2021. The sampling sites are located at the Najin Campus of Tibet University in Lhasa, and Tibet Agricultural and Animal Husbandry University in Nyingchi, Tibet. Temporary environmental pollution monitoring stations were set up, equipped with instruments including Thermo gas analyzers, GRIMM 11-D portable aerosol size spectrometers, FMPS size spectrometers, AE-33 black carbon detectors and other related devices. Concentrations of atmospheric pollutants such as ozone (O3), nitrogen dioxide (NO2), particulate matter (PM), ultrafine particles (UFP) and black carbon (BC) were monitored online, while meteorological data including temperature, humidity, atmospheric pressure and other relevant parameters were collected via a Vantage Vue wireless automatic weather station. Outliers during instrument operation were removed, and calibration procedures were implemented. The cleaned data has a temporal resolution of 1 hour. This dataset provides foundational data for comprehensively evaluating the health effects of air pollution on the local population in the Tibet Autonomous Region.
