Aerosol fine and coarse particle information extraction methods and system using more than two wavelength extinction

摘要

The present invention uses two wavelengths at the same time as the PM10 and PM2.5 measured values, or a dissipation factor of two or more wavelengths that can obtain both the total amount and size information of ultrafine dust and coarse particles by using a dissipation factor from four or more different wavelengths. It relates to a method and system for extracting the total amount and size of ultrafine dust and coarse particles using.
