This book was released on 1984 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part of this report addresses the status of the AVAP (Airport Vicinity Air Pollution) model and AQAM (Air Quality Assessment Model) from the perspective of the modeling requirements of users concerned with air-quality problems in civilian and military aviation. Brief descriptions of the types of problems likely to be encountered is followed by a detailed discussion of those characteristics of the problems that determine the technical requirements for the applicable computation procedures or models. This is followed by a discussion of the operational or user requirements of the models. Then a review and evaluation of the AVAP model and AQAM is given that includes a discussion of their intended uses, strengths, and weaknesses. The methods used by the two models to treat various aspects of the emission and dispersion are compared, and the best methods are selected, or alternatives are recommended where appropriate. The latter portion of the report addresses the future needs. Because of the number of interrelated problems and decisions required to meet these needs, a systematic approach to the problem in the form of a 'decision tree' is presented. The final section contains an outline of a proposed new computational system that should alleviate at least some of the problems identified in earlier sections. Two objections were paramount in the new design: to make the model easier to use and to be able to implement the model on modern, small computers.

Download or read book Airport Vicinity Air Pollution Model written by I. T. Wang and published by . This book was released on 1976 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes in detail the computer code of the Airport Vicinity Air Pollution (AVAP) model and the variables required to exercise the model. The AVAP model is a computerizing comprehensive airport simulation model which can serve as a tool in evaluating the total air quality impact of all airport operations on the airport vicinity. The report focusses on the operational procedures and descriptions of the structure and function of the computer code. The structure, chain of command that links the subroutines, and the more important computational subroutines are illustrated in detailed flow diagrams. The basic formulas used in the calculations are presented. One section provides guidelines for preparation of the input data and can serve as a 'mini' instruction manual by itself. Procedures are described by which the airport and environ data can be collected and cast into the proper forms. The data deck formating, variable limits and omissions permitted, and the computer configuration required to run the code are discussed. Samples of input and output are included.

This book was released on 1980 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the results of the Federal Aviation Administration (FAA)/Environmental Protection Agency (EPA) air quality study which has been conducted to assess the impact of aircraft emissions of carbon monoxide (CO), hydrocarbons (HC), and oxides of nitrogen (NOx) in the vicinity of airports. This assessment includes the results of recent modeling and monitoring efforts at Washington National (DCA), Los Angeles International (LAX), Dulles International (IAD), and Lakeland, Florida airports and an updated modeling of aircraft generated pollution at LAX, John F. Kennedy (JFK) and Chicago O'Hare (ORD) airports. The Airport Vicinity Air Pollution (AVAP) model which was designed for use at civil airports was used in this assessment. In addition the results of the application of the military version of the AVAP model the Air Quality Assessment Model (AQAM), are summarized.

This book was released on 2012 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a guide for airport operators on effective procedures for using air quality models in combination with on-site measurement equipment to prepare a comprehensive assessment of air pollutant concentrations in the vicinity of airports. It is designed to help practitioners generate information desired by local communities as they seek to develop more detailed local air quality assessments as well as respond to regulatory needs, including those of the National Environmental Policy Act (NEPA). The guide provides in-depth information on the capabilities and limitations of modeling and measurement tools, adding to an increasing knowledge base concerning preparation of air quality assessments near airports. Starting with the Federal Aviation Administration's (FAA) regulatory EDMS/AEDT, it describes how best to use available models, in combination with potential on-site monitoring programs, to conduct air quality assessments. Detailed information on the monitoring campaigns and modeling assessments is included in a set of appendices that accompany the guide. The appendices (available in CRP-CD-115) describe the models tested and the various equipment used to collect data, the rationale behind the selection of Washington Dulles International Airport as a case study application, and the components and steps involved in the measurement campaigns, and include an assessment of the various model outputs--

This book was released on 1984 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the results of three related studies conducted to assess the impact of aircraft emissions of nitrogen oxides (NOx) and hydrocarbons (Hc) on air quality. The first study consisted of a field program carried out at O'Hare International Airport and an associated model development program, the purposes of which were to assess the effect of aircraft NOx emissions on ambient 1-hour concentrations of nitrogen dioxide (NO2) and to provide a dispersion model suitable for the prediction of such concentrations. The second study involved the collection and laboratory analysis of samples of hydrocarbons in ambient air contaminated by jet aircraft exhaust, together with a determination of the type and relative amounts of the various hydrocarbons detected. The third study consisted of an analysis, based on available data in the literature, of the potential role of aircraft hydrocarbon emissions in the production of photochemical smog. The available literature dealing with the issue of aircraft contributions to photochemical smog has been reviewed and is discussed. At present, the available information is insufficient to evaluate the effect quantitatively. The requirements for further work that would enable a quantitative evaluation to be made are discussed.
