A 2-meter-long cell has been devised in which aerosol extinction and scattering coefficients can be measured simultaneously. Extinction is obtained by measuring the change in the intensity of a HeNe laser beam which is stepped through the cell for a total path length of 20 meters. A reciprocal nephe...
