Abstract: Abstract Photothermal spectroscopy, and photothermal interferometry (PTI) in particular, has the potential to provide reference measurements of aerosol absorption coefficients βabn. Such βabn measurements represent a fundamental property of aerosols such as black carbon and… read more here.
