The Aethalometer collects and analyzes aerosol particles continuously. The aerosol-laden air stream is drawn through a spot on a filter tape at a measured flow rate. Simultaneously, the tape is illuminated by light: sensitive detectors measure the intensities of light transmitted through an un-exposed portion of the tape, acting as a reference; versus the collecting spot. As optically absorbing material accumulates on the spot, the intensity of light transmitted through it gradually decreases. The decrease in light intensity from one measurement to the next is interpreted as an increase in collected material. This increased amount is divided by the known air-flow volume to calculate the concentration.
The real-time analysis is performed at 7 optical wavelengths from the near-ultraviolet (370 nm) to the near-infrared (950 nm), which enables source apportionment – see below – to separate traffic or diesel exhaust from biomass burning (woodsmoke, forest fires, cook stoves…), and Brown Carbon calculations.
Receive accurate real-time data on Black Carbon, an important particulate matter component, that causes serious environmental and health-related risks. AE36 enables identification of Black Carbon sources and provides an assessment of air quality with the Black Carbon BC Index. Access AE36 and receive valid data remotely, without post-processing. AE36 with a new user interface is easy to use and can run unattended for almost a year. Built on four decades of scientific work and real-world experience for robust and reliable operation, ensuring data continuity for long-term trend analysis.
