  Real time Black Carbon (BC) concentrations are most commonly determined using filter-based measurements of aerosol optical absorption.Measurements at multiple wavelengths permit the separation of contributions of BC from different combustion sources.Filter-based methods can suffer from non-linearity due increasing sample deposit on the filter.
