Abstract: A new method of solution of the advection-diffusion equation is developed; the key feature of the method is the approximate conservation of the zeroth, first and second moments of pollutant mass, with the assumption of ...

Abstract: Radioactive fallout data suggest that the concentration of pollutants in rainfall, while highly variable, might be described on the average by about an inverse half-power dependence on the amount of precipitation. Recent ...

Abstract: The diurnal variation of the structure of pollutant transport and diffusion in the Ohio River Valley is examined by combining meteorological cross sections with vertical profiles of several air pollutants. An increased ...

Abstract: A field campaign was carried out near Boardman, Oregon, to study the effects of subgrid-scale variability of sensible-and latent-heat fluxes on surface boundary-layer properties. The experiment involved three U.S. Department ...

Abstract: A boundary layer field experiment in the Mexico City basin during the period 24 February?22 March 1997 is described. A total of six sites were instrumented. At four of the sites, 915-MHz radar wind profilers were deployed ...
