AOS: 3 wavelength Particle Soot Absorption Photometer - aospsap3w

The particle soot absorption photometer collects aerosol particles on a substrate and measures the change in light transmission relative to a reference filter. Bulk particle absorption is derived after correcting for scattering effects. \n \nThe PSAP is part of the aerosol observing system (AOS).

烟炱颗粒吸收光度计（particle soot absorption photometer，简称PSAP）将气溶胶颗粒采集至采样基底表面，并测定其相对于参比滤膜的光透射率变化量。在校正散射效应后，可推导得到整体颗粒吸光度。

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