Meteorological modeling system for the description of atmospheric states and motions. |
JPROC |
Photolysis rate processor. | SMOKE |
Emission models for man-made and natural emissions that are injected into the atmosphere. |
ICON |
Initial conditions processor. | CCTM
|
Chemistry-transport modeling system for simulation of the chemical transformation and fate. |

CCTM |
CMAQ Chemical-transport model processor. | ||
The Mesoscale Model Version 5, MM5, and the MCIP2 processor provide a complete set of meteorological data needed for CCTM, while ICON and BCON process initial and boundary conditions, respectively. The emissions-chemistry interface, Sparse Matrix Operator Kernel Emissions (SMOKE) system, combines area and point source emissions to generate three-dimensional gridded emission data for CCTM. A photolytic rate constant processor, JPROC, computes species-specific photolysis rates for a set of predefined zenith angles and altitudes. In addition, a Plume Dynamics Model (PDM) is used to provide major elevated point-source plume dispersion characteristics for driving the plume-in-grid processing within CMAQ.
