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

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.本数据集经采集与研究，旨在探究微黑碳仪（micro-aethalometer）MA300型号的性能表现。微黑碳仪是用于测量黑碳（Black Carbon, BC）质量浓度的便携式仪器，可实现多波长光吸收测量，进而可用于开展黑碳的来源识别工作。本研究通过在一处交通路口布设三台MA300型微黑碳仪开展长期野外监测，旨在采集涵盖交通排放源的黑碳数据。本次数据采集时段与2020年夏季受野火烟霾影响的日期重合。三台MA300型微黑碳仪均部署于温哥华市克拉克大道的大都会温哥华（Metro Vancouver）监测站内。
