拉萨河流域上游大气环境质量观测数据（2021-2023）

该数据是拉萨河流域地球系统多圈层变化观测研究的重要组成部分，数据为在流域上游廓琼岗日冰川区大气环境质量的实时监测数据。数据涉及的指标主要有：颗粒物（PM10、PM2.5、二氧化硫、氮氧化合物、一氧化碳、臭氧），该数据由第二次青藏科考办公室人员进行数据质量审核，数据分辨率是1小时。该数据是拉萨河流域上游自然过程主导区的实时、多参数监测数据，能够为研究全球变化和人类活动共同影响背景下，区域环境变化等提供高分辨率的数据支撑。通过对该自然过程主导区大气环境质量数据的分析，结合下游的大气环境质量研究数据，可以为判断区域大气环境质量风险状态提供科学依据。

This dataset is an important component of the observation and research on multi-sphere changes of the Earth system in the Lhasa River Basin. It comprises real-time monitoring data of atmospheric environmental quality collected in the Kuoqinggangri Glacier Area, the upper reaches of the basin. The main monitored indicators include particulate matter (PM10, PM2.5), sulfur dioxide, nitrogen oxides, carbon monoxide, and ozone. This dataset has undergone data quality verification by staff from the Second Tibetan Plateau Scientific Expedition and Research (STEP) Office, with a temporal resolution of 1 hour. As real-time, multi-parameter monitoring data from the natural process-dominated region in the upper reaches of the Lhasa River Basin, this dataset can provide high-resolution data support for studies on regional environmental changes under the combined impact of global change and human activities. By analyzing the atmospheric environmental quality data from this natural process-dominated region and combining it with relevant atmospheric environmental quality monitoring data from the downstream area, it can offer a scientific basis for evaluating the risk status of regional atmospheric environmental quality.
