Cairpol and Aeroqual air quality sensors measuring CO, CO, NO, and other species were tested in fresh biomass burning plumes in field and laboratory environments. We evaluated sensors by comparing 1-minute sensor measurements to collocated reference instrument measurements. Sensors were evaluated based on the coefficient of determination ( ) between the sensor and reference measurements, by the accuracy, collocated precision, root mean square error (RMSE), and other metrics. In general, CO and CO sensors performed well (in terms of accuracy and values) compared to NO sensors. Cairpol CO and NO sensors had better sensor-versus-sensor agreement (e.g., collocated precision) than Aeroqual CO and NO sensors of the same species. Tests of other sensors (e.g., NH, HS, VOC, NMHC) provided more inconsistent results and need further study. Aeroqual NO sensors had an apparent O interference that was not observed in the Cairpol NO sensors. Although the sensor accuracy lags that of reference-level monitors, with location-specific calibrations they have the potential to provide useful data about community air quality and personal exposure to smoke impacts.
在野外和实验室环境中，对用于测量一氧化碳（CO）、二氧化碳（CO₂）、氮氧化物（NO）及其他成分的凯尔宝（Cairpol）和艾罗夸尔（Aeroqual）空气质量传感器进行了测试，测试环境为新鲜生物质燃烧羽流。我们通过将传感器1分钟的测量结果与并置的参考仪器测量结果进行比较，来评估这些传感器。根据传感器测量值与参考测量值之间的决定系数（ ）、准确度、并置精度、均方根误差（RMSE）及其他指标对传感器进行评估。总体而言，与氮氧化物传感器相比，一氧化碳和二氧化碳传感器表现良好（在准确度和 值方面）。凯尔宝一氧化碳和氮氧化物传感器在传感器之间的一致性（例如，并置精度）方面，比同类型的艾罗夸尔一氧化碳和氮氧化物传感器更好。对其他传感器（如氨气（NH₃）、硫化氢（H₂S）、挥发性有机化合物（VOC）、非甲烷烃（NMHC））的测试结果更不一致，需要进一步研究。艾罗夸尔氮氧化物传感器存在明显的氧干扰，而在凯尔宝氮氧化物传感器中未观察到这种情况。尽管传感器的准确度落后于参考级监测器，但通过特定地点的校准，它们有潜力提供有关社区空气质量和个人烟雾暴露影响的有用数据。
