GM calculator
for a geometric mean size of a given particle size distribution
This software can calculate a geometric mean and a geometric standard deviation of aerodynamic diameters of a given particle size distribution. Users are requested to enter particle concentrations (ug/m3, N/m3, etc) of each size bin. We will be able to modify particle size bins used in the software. If you need modifications, please let us know through the support page. For more detail, please see and cite our following paper:
