“…The inner most domain has the coverage of 140km × 140km which includes the whole area of interest. The high resolution will help the meteorological model to resolve the unique weather phenomena occurring over a complex area such as El Paso [2], where mountainous topography produces regional circulation that results in wind in the mountains and valleys, which consequently affects the local pollutant transportation and dispersion. The vertical layers of WRF contain 35 sigma levels with 15 layers within the planetary boundary layer (PBL) (less than 1500 m), in which the lowest sigma level is at a height of 12 meters.…”

“…1) to study the relationships between ozone and its natural and anthropogenic precursors. Some studies have been conducted to investigate the 1996 Paso del Norte Ozone Campaign in order to develop an understanding of the chemical and physical processes which influence high ozone concentrations in the Paso del Norte study area [2, 9, 12, 13, 23, 31]. Most of these studies were diagnostic, and modeled the case by adapting an idealized profile [2].…”

Surface ozone pollution has been a persistent environmental problem in the US and Europe as well as the developing countries. A key prerequisite to find effective alternatives to meeting an ozone air quality standard is to understand the importance of local anthropogenic emissions, the significance of biogenic emissions, and the contribution of long-range transport. In this study, an air quality modeling system that includes chemistry and transport, CMAQ, an emission processing model, SMOKE, and a mesoscale numerical meteorological model, WRF, has been applied to investigate an ozone event occurring during the period of the 1996 Paso del Norte Ozone Campaign. The results show that the modeling system exhibits the capability to simulate this high ozone occurrence by providing a comparable temporal variation of surface ozone concentration at one station and to capture the spatial evolution of the event. Several sensitivity tests were also conducted to identify the contributions to high surface ozone concentration from eight VOC subspecies, biogenic VOCs, anthropogenic VOCs and long-range transportation of ozone and its precursors. It is found that the reductions of ETH, ISOP, PAR, OLE and FORM help to mitigate the surface ozone concentration, and like anthropogenic VOCs, biogenic VOC plays a nonnegligible role in ozone formation. But for this case, long-range transport of ozone and its precursors appears to produce an insignificant contribution.

“…Surface properties are defined for 14 land use classes and the model includes urban and forest canopy parameterisations ( Figure 2). Brown et al (2001) and Wang & Ostoja-Starzewski (2004b) applied this model for ozone study in the Paso del Norte area and obtained very good results. It was also the first time that this model was successfully applied with a resolution of 1 km.…”

“…Using field data collected from two casestudy periods during 1998 within Phoenix, the ability of a state-of-the-art mesoscale atmospheric circulation model, HOTMAC (Higher Order Turbulence Model for Atmospheric Circulation), with a hydrostatic approximation, to replicate the atmospheric flow within the Phoenix Valley ( Figure 1) was analysed spatially and temporally. Such a hydrostatic-based HOTMAC model capable of simulating circulation patterns over a relatively fine grid spacing in nested coordinate system (1 km) has already been successfully applied in the ozone study in the El Paso area by Brown et al (2001). This allows the role of topography in generating a convergent wind regime in the Phoenix area to be determined more accurately.…”

A three-dimensional time-dependent mesoscale meteorological model, called HOTMAC, is applied to study the complex terrain airshed of El Paso/Ciudad Juarez staring from November 29 and ending at December 2, 1998. The model numerically solves the equations for mass, momentum, heat and moisture in terrain following coordinates using the alternating direction implicit (ADI) finite difference scheme. The model accounts for solar and terrestrial radiation effects, whereby the lower boundary conditions are defined by a surface energy balance and surface layer similarity theory, and the soil heat flux is obtained by solving a 5-level heat condition equation in the soil. Surface properties are defined for 14 landuse classes and the model includes urban and forest canopy parameterizations. For the Paso del Norte region, four nested meshes (1, 2, 4 and 8 km resolution) horizontally and 22 vertical grid levels were used, with the top of the modeling domain being 6000 m. To account for synoptic-scale weather variations, a nudging scheme was employed. The numerical wind results are compared with observations made in the Paso del Norte area. Finally, using the wind and turbulence output from HOTMAC, the particle plume trajectory information was obtained using the 'puff dispersion' model, RAPTAD, to capture details of the pollutant motions.
