我们描述了一种实时测量光吸收气溶胶颗粒浓度的仪器。这种吸收通常是由于黑碳，这是一个很好的燃烧排放示踪剂。最小解析时间从城市环境的几秒钟到偏远地区的几分钟不等。我们介绍了在飞机上运行时所获得的结果。由于时间分辨能力，我们可以确定吸收气溶胶的空间分布。从希腊语“αιϑλoυν”，“用煤烟熏黑”，我们将这种仪器命名为“气压计”。
We describe an instrument that measures the concentration of optically absorbing aerosol particles in real time. This absorption is normally due to black carbon, which is a good tracer for combustion emission. The minimum resolving times range from seconds in urban environments to minutes in remote locations. We present results obtained during operation on an aircraft. Due to the time resolution capability, we can determine the spatial distributions of absorbing aerosol. From the Greek word “αιϑλoυν,”“to blacken with soot,” we have named this instrument the aethalometer.
