Performance evaluation of portable dual-spot micro-aethalometers for source identification of Black Carbon aerosols: Application to wildfire smoke and traffic emissions in the Pacific Northwest

<p>This data has been collected and studied to understand the performance of the micro-aethalometer model MA300. Mirco-aethalometers are portable instruments for measuring Black Carbon (BC) mass concentrations. These instruments are facilitated to measure light absorption in multiple wavelengths, which can be utilized to perform source identification of BC. Through a long-term field deployment of three units of MA300s, we aimed to collect BC data at a traffic junction, covering sources from Traffic emissions. The data collection period overlapped with the Wildfire smoke-affected days in the Summer of 2020. All three MA300 units were operated inside Metro Vancouver's monitoring station at Clark Drive, Vancouver.</p>

本数据集旨在通过采集与分析数据，探究微型黑碳仪（micro-aethalometer）MA300型号的性能表现。微型黑碳仪是用于测量黑碳（Black Carbon, BC）质量浓度的便携式仪器，具备多波长光吸收测量能力，可用于开展黑碳的来源识别工作。本研究通过部署三台MA300设备开展长期野外监测，旨在于一处交通枢纽点位采集黑碳数据，覆盖交通排放相关污染源。数据采集时段与2020年夏季受野火烟雾影响的日期重合，三台MA300设备均运行于位于温哥华克拉克大道的大温哥华（Metro Vancouver）地区监测站内。
