  • Validation of atmospheric dispersion models using ETEX data

    Two models frequently used to simulate the dispersion of pollutants in the atmosphere have been compared. This is necessary because only a well-tested and well-calibrated simulation model can be a good representation of the reality of the dispersion of pollutants. The models evaluated (HYSPLIT_4 with its four variants and MEDIA) were run using as input parameters the same meteorological dataset ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • The Atmospheric Dispersion Modelling System (ADMS): comparisons with data from the Kincaid experiment

    In order to test the ability of a model its results must be compared with experimental data; hence validation work is an essential part of the development of any model. This paper presents the results of a validation study of the UK Atmospheric Dispersion Modelling System (UK-ADMS) version 1.06, a short-range dispersion model, against the results of the Kincaid field experiment. Predictions of ...

  • GAW Regional Station for Atmospheric Research

    The aim of the JRC-Ispra station is to monitor the concentration of pollutants in the gas phase, the particulate phase and precipitations, as well as aerosol optical parameters, which can be used for assessing the impact of European policies on air pollution and climate change. It is particularly well suited for the participation in international monitoring programs like the Co-operative program ...


  • Atmospheric impact of a municipal wastes incinerator

    This paper presents a case study of an air pollution dispersion model for the atmospheric impact assessment of a new municipal wastes incinerator (MWI). The capacity of the present MWI will increase more than ten times, and a new high-efficiency flue gas treatment system is projected. The environmental impact study has been focused on the long-term aspect of the air pollution (chronic pollution) ...

  • Emissions of Atmospheric Pollutants in Europe, 1990–99

    This report presents indicators and information on air emission trends in Europe 1990–99. Atmospheric pollution contributes to several prominent environmental issues that arise due to emissions to the atmosphere (air emissions) from a variety of mainly anthropogenic (man-made) activities. This report covers air emissions that contribute to the following issues: • acidification and ...


  • Evaluation of new generation atmospheric dispersion models

    The paper considers the regulatory view of evaluating dispersion models. There is no proscription for regulatory studies in the UK, so differences between dispersion calculations from different models and versions of models are then as important as their absolute veracity. An example shows variations in calculated concentration due to variations between two different versions of a model and two ...

  • A review of evaluation procedures for atmospheric dispersion models

    Evaluation of atmospheric dispersion models is vital to justify their use within the air quality component of environmental assessments. The Model Validation Kit, compiled and distributed by Helge Olesen of NERI, is often used for such evaluations. Whilst the Model Validation Kit has a wide range of functionality, its users often limit their evaluation to a few simplistic calculations. ...

  • GAW Regional Station for Atmospheric Research - 2005 Report

    The aim of the JRC-Ispra station is to monitor the concentration of pollutants in the gas phase, the particulate phase and precipitations, as well as aerosol optical parameters, which can be used for assessing the impact of European policies on air pollution and climate change. Measurements are performed in the framework of international monitoring programs like the Co-operative program for ...


  • Canarina DISPER software · atmospheric Chemistry · commands 24

    Here, only some data can be modified. The necessary data is:   Pollutant emission rate (g/m s): This is the pollutant emission rate.   Decay coefficient (1/s): This coefficient considers the half life of the pollutant if this ...

  • Modelling and measurements of the atmospheric boundary layer in Sofia, Bulgaria

    The evaluation of mesoscale model simulations against experimental data on the vertical profiles of mean meteorological parameters and surface turbulent momentum and heat fluxes for Sofia, Bulgaria, is presented. The simulation of the vertical profiles is currently a weak point in mesoscale modelling, and needs investigation in view of the numerous practical applications.Keywords: Bulgaria, ...

  • Evaluations of urban atmospheric transport and dispersion models using data from the Joint Urban 2003 field experiment

    We have evaluated the performance of several urban Atmospheric Transport and Dispersion (AT&D) models by comparing model predictions to tracer gas concentrations measured during the Joint Urban 2003 field experiment in Oklahoma City, USA. These models include the Urban Canopy, Urban Dispersion Model (UDM), and Micro–SWIFT/SPRAY (MSS) modes within the HPAC modelling suite, QUIC–URB/QUIC–PLUME ...

  • Simple model of the Urban Atmospheric Boundary Layer (UABL)

    The horizontally homogeneous atmospheric boundary layer over a rough surface with a large roughness length z0 has been investigated to model the simplest cases of the Urban Atmospheric Boundary Layer (UABL) over a flat plain. It has been demonstrated that the nondimensional profiles of the horizontal Reynolds stresses of eddy viscosity and of velocity defect components are universal and ...

  • Modelling of atmospheric pollutant dispersion in coastal areas

    Some characteristics of air pollution in Tarragona (Spain) were investigated. Tarragona has an important petrochemical industry in a coastal region with a complex terrain. The study was made numerically in sea breeze conditions with a three-dimensional mesoscale meteorological model. The temporal and spatial variations of the wind fields have been used in the Lagrangian equation for a ...

  • Assessment of particulates in the urban atmosphere of Sao Carlos, Brazil

    A survey on the concentration of particulate matter in the urban atmosphere was carried out in the city of Sao Carlos, Brazil. Five sites were selected for data collection one in the city centre (high concentration of people and automotive vehicles), three in industrial areas, and one at the interface with the countryside. The particle size distribution and mass concentration, temperature, ...
