What Does GMAD Stand For?

GMAD stands for Geometric Mean Aerodynamic Diameter

GMAD, or Geometric Mean Aerodynamic Diameter, is a crucial parameter used in aerosol science and engineering to characterize the size distribution of particles in the air. It represents the diameter at which half of the total particle volume is made up of particles larger than this diameter and half from particles smaller. By providing a single value to describe a potentially complex distribution, GMAD aids in assessing the behavior, transport, and deposition of aerosol particles in various environments, impacting health, environmental studies, and industrial applications.
