This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Idealized large-eddy simulations were performed to investigate the impact of different mountain geometries on daytime pollution transport by thermally driven winds. The main objective was to determine interactions bet...

nowadays, transportation sector consumes about 27 percent of the whole energy in iran. therefore, after domestic and business sectors which consume about 40 percent of the whole energy, transportation is placed in the second rank. however, the financial value of transportation is of the highest importance. moreover, having 55percent of gasoline product consumption transportation has been also r...

Atmospheric mercury can be considered a ‘hot topic’. The problem of global mercury pollution is a focus of several international conventions such as the UNEP mercury program and the UN-ECE Long-Range Transport of Atmospheric Pollution Convention Task Force on Hemispheric Transport of Air pollution (HTAP). Major scientific questions are the oxidization processes of elemental mercury, global and ...

Optimization of timetable is the need of the day for the rescheduling and routing of trains in real time. Trains are scheduled in parallel with the road transport vehicles to the same destination. As the number of trains is restricted due to single track, customers usually opt for road transport to use frequently. The air pollution increases as the density of vehicles on road transport is incre...

The objective of this paper is to describe governing numerical equation and solution algorithm of pollution transport mechanisms and factors essential to include in developing relatively simple and practical tools to quantify pollution loss, advection, diffusion and sorption in pollution transport into the groundwater at landfill sites. This paper presents the development of a numerical model t...

accurate prediction of pollution control and environmental protection need a good understanding of pollutant dynamics. numerical model techniques are important apparatus in this research area. so a 2500 line fortran 95 version code was conducted in which using approximate riemann solver, couples the shallow water and pollution transport agents in two dimensions by the aid of unstructured meshes...

We use aircraft observations of carbon monoxide (CO) from the NASA ARCTAS and NOAA ARCPAC campaigns in April 2008 together with multiyear (2003– 2008) CO satellite data from the AIRS instrument and a global chemical transport model (GEOS-Chem) to better understand the sources, transport, and interannual variability of pollution in the Arctic in spring. Model simulation of the aircraft data give...
