Mass Median Aerodynamic Diameter

Term · Environment · MLC-T-ENV-016621

Median of the distribution of airborne particle mass with respect to the aerodynamic diameter. MMADs are usually accompanied by the geometric standard deviation (g or sigma g) which characterizes the variability of the particle size distribution.
