Operational Multiscale Environment model with Grid Adaptivity (OMEGA)

The Operational Multiscale Environment mode with Grid Adaptivity (OMEGA) and its embedded Atmospheric Disperision Model (ADM) was designed to support critical studies and forecasts of hazardous atmospheric dispersal. OMEGA is a multiscale, non-hydrostatic atmospheric simulation model with an adaptive grid that permits a variable horizontal spatial resolution that ranges from 100 km to 1 km without wave-reflecting internal boundaries. The model contains a 2.5 level explicit boundary layer formulation , surface layer physics with multiple soil layers and 12 soil types, a sophisticated explicit microphysics package with five water species and a four dimensional data analysis scheme based on the optimum interpolation technique. ADM is an atmospheric dispersion model that computes the dispersion of aerosols and gases.
