Factors controlling pollutant plume length downwind of major roadways in nocturnal surface inversions

A fitting method using a semi-empirical Gaussian dispersion model solution was successfully applied to obtain both dispersion coefficients and a particle number emission factor (PNEF) directly from ultrafine particle (UFP; particles smaller than <0.1 μm in diameter) concentration profiles observe...
