Dust storms/aerosols and ozone
PRCM has coupled dust/aerosol modules (including source function, transport, deposition, and dispersion ) and chemistry modules to study the transport and distribution of aerosols, the direct and indirect effects of aerosols on climate, etc. The following figures show that the model is capable of reproducing the observed pattern of dust during the severe dust storm occurred in April of 1998.
