Dust particles in the mesopause are negatively charged despite photoelectric emission. They tend to deplete ionization by more or less sequential capture of electrons and positive ions. For a given particle radius, the charge of a dust particle may be assumed to be a unique number or, more rigorously, it may be specified as a distribution function characterized by a mean charge. The latter refinement amounts, however, to only a 15% improvement of the value of the depletion coefficients. The depletion coefficients are smaller by approximately 50% if allowance is made for the photoelectric emission from the dust particles. The depletion coefficient increases almost linearly with the square of the dust particle radius. The role of dust particles in governing the ionization density in the mesopause is important but not dominant. It becomes dominant only when the number density of charged particles exceeds a cb cm and the particle radius exceeds 10 to the -5th power.
