北京大气中PM2.5质量浓度站点观测数据集（2008年夏季）

本数据集包含了2008年夏季北京市区和郊区站点PM2.5的质量浓度。分别使用Thermo Andersen RAAS2.5-400和Mini Vol PM2.5采样器在环科院和黑山寨采集大气中PM2.5样品，并使用百万分之一天平（ME5，Sartorius）对滤膜采集PM2.5样品前后的重量进行称量。共获得140条数据，数据类型为属性数据。采集目的为研究2008年奥运会期间北京市区及郊区PM2.5的质量浓度，属于大气环境学范围。数据服务于从事大气环境研究的学生和科研人员。

This dataset contains mass concentration measurements of PM2.5 collected at urban and suburban sites in Beijing during the summer of 2008. PM2.5 samples were collected at the Chinese Research Academy of Environmental Sciences and Heishanzhai using Thermo Andersen RAAS2.5-400 and Mini Vol PM2.5 samplers, respectively. The weights of the filters before and after PM2.5 sampling were measured using a microbalance (ME5, Sartorius) with a readability of one microgram (one millionth of a gram). A total of 140 attribute-type data entries were obtained. The sampling campaign was conducted to investigate the mass concentration of PM2.5 in urban and suburban Beijing during the 2008 Olympic Games, which falls within the scope of atmospheric environmental science. This dataset serves students and researchers engaged in atmospheric environmental research.
