  • Development of a Line Source Dispersion Model for Gaseous Pollutants by Incorporating Wind Shear Near the Ground Under Stable Atmospheric Conditions †
    Proceeding Paper Development of a Line Source Dispersion Model for Gaseous Pollutants by Incorporating Wind Shear near the Ground under Stable Atmospheric Conditions † Saisantosh Vamshi Harsha Madiraju and Ashok Kumar * The College of Engineering, The University of Toledo, Toledo, OH 43606, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-419-530-8136 † Presented at the 3rd International Electronic Conference on Atmospheric Sciences, 16–30 November 2020; Available online: https://ecas2020.sciforum.net/. Abstract: Transportation sources are a major contributor to air pollution in urban areas. The role of air quality modeling is vital in the formulation of air pollution control and management strategies. Many models have appeared in the literature to estimate near-field ground level concentrations from mobile sources moving on a highway. However, current models do not account explicitly for the effect of wind shear (magnitude) near the ground while computing the ground level concentra- tions near highways from mobile sources. This study presents an analytical model based on the solution of the convective-diffusion equation by incorporating the wind shear near the ground for gaseous pollutants. The model input includes emission rate, wind speed, wind direction, turbu- lence, and terrain features. The dispersion coefficients are based on the near field parameterization. The sensitivity of the model to compute ground level concentrations for different inputs is presented for three different downwind distances. In general, the model shows Type III sensitivity (i.e., the Citation: Madiraju, S.V.H.; Kumar, errors in the input will show a corresponding change in the computed ground level concentrations) A.

The annoyance The task to find out the best dependence of the equivalent produced by noise, in fact, can heavily influence the quality of human noise level from the vehicular flow and from other parameters life. Thus, a proper modeling of the source and of the propagation can has been pursued in many papers ([7-12] and references give important assistance to the noise prediction and thus to the urban planning and development design. In this paper, the authors approach therein). In this paper, the authors consider two experimental these issues by means of field measurements analysis, defining and sets of data taken contemporary in three different points, at evaluating a “degree of linearity” coefficient, related to the power four different distances from the road. Since the source during law of the source-receiver distance in the logarithmic propagation each measurement can be assumed to be the same for all the formula. This value is expected to be 10 in the linear scheme, i.e. the receivers, an interesting comparison between measured levels approach of several literature studies and regulation models, or 20 in can be performed. The distances difference can be used to test the point scheme. Plotting the results for this parameter in the two available sets of experimental data, the authors will corroborate the the dependence of the level from the source-receiver distance, linear hypothesis.

May 28, 2015 By Bill Adams — 6 Comments A nearby roadway may be putting your household’s health at risk. The same is true of workplaces, schools, and other places where people spend signifcant time. This health risk is from the elevated auto emissions near high trafc roadways. It’s a health risk separate and in addition to the regional air pollution from auto emissions. We have come to draw a false sense of security from our collective sharing of regional air pollution and, perhaps, the belief that regulatory agencies protect us. However, research continues to show that air pollution, particularly from auto emissions, has profound efects on health. Moreover, such impacts are unequally distributed among local populations, largely based on nearness to major roadways. Discussions about whether or not to build or expand roadways are dominated by the topics of trafc congestion relief, urban planning, and greenhouse gasses. The impact of roadways on Americans’ health and morbidity is often lost in the discussions. 53,000 U.S. deaths annually Additional Documentation Attachment to Comment Letter 2-F2 are attributable to automobile emission air pollution. (Calazzo, et al., 2013) Many more are ill or incapacitated from auto emissions. Ninety percent of the cancer risk from air pollution in Southern California is attributable to auto emissions.

The model is designed to simulate mobile source pollutant 34 dispersion to support the assessment of human exposures in near-roadway environments 35 where a significant portion of the population spends time. The model uses an efficient 36 numerical integration scheme to integrate the contributions of point sources used to represent 37 a line-source. Emphasis has been placed on estimates of concentrations very near to the 38 source line. The near-surface dispersion algorithms are based on new formulations of 39 horizontal and vertical dispersion within the atmospheric surface layer, details of which are 40 described in a companion paper (Venkatram et al. 2013), This paper describes the general 41 formulations of the RLINE model, the meteorological inputs for the model, the numerical 42 integration techniques, the handling of receptors close to the line source, and the performance 43 of the model against developmental data bases and near-road concentrations from 44 independent field studies conducted along actual highway segments.
