Black Carbon, or Soot, is the second-leading cause of global warming, may account for half of Arctic warming, and makes people sick - it is a leading cause of respiratory illness and premature death.

The microAeth is a self-contained, pocket-sized instrument with flow control, data storage, and battery and makes its analysis by collecting particulates on a replaceable filter strip and utilizes the Aethalometer optical absorption technique to determine the mass concentration of Black Carbon in real time. The data can then be downloaded to a computer or uploaded to a server for subsequent processing and visualization.
