便携式黑碳仪AE43

AE43是实时观测黑碳气溶胶的便携式仪器，可同时 在紫外、可见和近红外的7个波长上对大气黑碳气溶胶进行长期观测。

同时使用370, 470, 520, 590, 660, 880 和 950nm七波段的光源测量黑碳气溶胶的光吸收。

The Aethalometer® draws the sample air stream through a filter tape with a flow rate from 2 to 5 liters per minute. Aerosols are collected on two spots on the tape, and are illuminated by a multi-wavelength light source. Detectors measure the attenuation of light by the absorbing components of the aerosols, relative to a reference through an un-exposed portion of the tape. The filter tape advances on a time schedule, or when a pre-set loading limit is reached. The instrument operates completely automatically from power-up, and provides continuous real-time data with no operator attention.
