Description: Atmospheric turbulent diffusion, Mesoscale wind flow, Lagrangian puff/plume dispersion. Abstract: The LINCOM/RIMPUFF plume dispersion model is used to simulate eight plume releases from the Mt. Iron study at Vandenberg AFB. LINCOM wind fields and RIMPUFF plume releases from the Mt. Iron study at Vandenberg AFB. LINCOM wind fields and RIMPUFF plume widths agree well with Mt. Iron but RIMPUFF plumes are longer, probably because the zinc sulfide tracer was not inert as previously assumed and was absorbed by the surface canopy. Bi-modal dose isopleths resulting from passage over Honda Canyon are not well simulated. Tower anchoring improves wind field simulation if tower measurements are accurate over the time scale of dispersion. Centerline dose scatter plots, fractional bias, normalized root mean square error, and dose isopleth correlation areas (DICA) performance measures are compared. Fractional bias and DICA appear to be most robust. LINCOM/RIMPUFF modeling theory is presented in detail.
