AOS: 3 wavelength Continous Light Absorption Photometer - aosclap3w

The continuous light absorption photometer (CLAP) operates on the same principle as the particle soot absorption photometer (PSAP), i.e., continuously measuring transmission through a filter substrate as sample air is drawn through it. The absorbing aerosol particles are collected in the filter. \n \nThe CLAP is part of the aerosol observing system (AOS).

连续光吸收光度计（continuous light absorption photometer，CLAP）的工作原理与颗粒炭黑吸收光度计（particle soot absorption photometer，PSAP）一致，即当采样空气抽滤通过滤膜基底时，持续监测其光透过率。吸收性气溶胶颗粒会被收集于该滤膜之上。

该CLAP属于气溶胶观测系统（aerosol observing system，AOS）的组成部分。
