Abstract: Cavity-enhanced/ring-down spectroscopy is one of the most widely used spectroscopy technique for the high sensitivity, real time, in-situ measurement of the aerosol extinction coefficient. The nature suspended state of the aerosol is not changed during the measurement. After nearly 30 years development, the techniques were well developed. The instrument based on cavity-enhanced/ring-down method was served as a standard instrument for the intercomparisons with other optical measurement instruments. In this paper, the development and the application of cavity-enhanced/ring-down spectroscopy for aerosol extinction measurement were briefly reviewed.

Key words: spectroscopy, Aerosol Extinction, Cavity enhanced absorption spectroscopy, cavity ring-down spectroscopy
