西藏墨脱地区气溶胶综合观测数据集（2021年4月-5月）

数据集包含西藏墨脱地区墨脱国家气候观象台（29°18’N，95°19’E，海拔1305.0米）的大气气溶胶PM10， PM2.5 和PM1数据以及环境空气温湿度。观测仪器为GRIMM-180 环境颗粒物分析仪，观测时间为2021年4月8日至2021年5月22日，数据时间分辨率为10秒，仪器工作过程中产生的异常数据已经剔除。在观测期间，由于受南亚季风影响，空气湿度较大，观测场地周边受人为活动干扰较少。本数据集为研究藏东南地区大气粉尘气溶胶物理特性、时空变化特征和来源解析提供了基础数据。资助项目：第二次青藏高原综合科学考察研究任务六专题二（2019QZKK0602）。

This dataset contains atmospheric aerosol PM10, PM2.5 and PM1 data as well as ambient air temperature and humidity data from the Motuo National Climate Observatory in Motuo, Tibet (29°18’N, 95°19’E, elevation 1305.0 m). The observation instrument is the GRIMM-180 Environmental Particulate Matter Analyzer, and the observation period was from April 8, 2021 to May 22, 2021, with a temporal resolution of 10 seconds. Abnormal data generated during the instrument's operation have been removed. During the observation period, affected by the South Asian monsoon, the ambient air humidity was relatively high, and there was little interference from human activities around the observation site. This dataset provides basic data for studying the physical properties, spatiotemporal variation characteristics and source apportionment of atmospheric dust aerosols in the southeastern Tibetan Plateau.
