| description | In this work was tested the use of output data from Regional Atmospheric Modeling System (RAMS) as input toan Eulerian Dispersion Model (EDM). Specifically was compared the ground level cross-wind integrated concentrationsimulated by EDM, using an eddy diffusivity valid to the Convective Boundary Layer (CBL) and two wind profiles: thefirst obtained by the Operationelle Meteorologiske Luftkvalitetsmodeller model (OML) and the second generated byRAMS mesoscale model. To accomplish the simulations with EDM were used data collected on the 07/06/1979 duringCopenhagen tracer experiment (emission rate, source height, convective velocity scale, CBL height, friction velocity,Monin-Obukhov length in the surface layer and roughness length). The performance of the two simulations was testedconfronting the ground level cross-wind integrated concentration generated with those observed in referred experiment. Forsimple topography area, such as the study area, the results showed that the use of a diagnosis model (OML) or a prognosticmodel (RAMS) to simulate the wind profile didn’t generate great differences between ground level cross-wind integratedconcentration simulated by EDM. |
