Influences of initial conditions and boundary conditions on regional and urban scale Eulerian air quality transport model simulations

摘要: Abstract Influences of initial and boundary conditions were quantified by analysis a simplified governing equation followed with tracer O 3 simulations using three-dimensional air quality transport model. The analytical solution derived from the indicated that impacts on given site decrease simulation time significantly affect species concentrations before arrival conditions. Boundary influences, which during downwind transport, are significant to selected when condition is short lifetime long. Non-reactive tracers then added SARMAP Air Quality Model (SAQM), model, results showed determine influences consistent obtained equation. Moreover, calculated ozone at proportional magnitude prescribed conditions, time, more obvious local nighttime. When 15 h, an average 64% will contribute concentrations. For times 23, 20, 7 ratios 26%, 34%, 79%, respectively. This study could be used modelers in estimating as long known.
