The value of accurate air quality forecasts

The value of accurate air quality forecasts critically depends upon how the information will be used. This paper proposes a simple model of private firm decision-making under uncertainty to consider potential economic applications and benefits from accurate air quality forecasts. It uses the findings of a survey of employees from five large employers in southern New Hampshire and northeastern ...

Lisbon air quality forecast using statistical methods

Ozone and particulate matter levels in Southern European countries are particularly high, exceeding the established limit values, and the information and alert thresholds (in the case of ozone). Therefore, it is relevant to develop a good prediction methodology for the concentrations of these pollutants. Statistical models based on Multiple Regression (MR) analysis and classification and ...

Correlation of air pollution and meteorological data using neural networks

In order to develop an environmental forecasting tool, the Neural Network method of computational intelligence is investigated. For this purpose, hourly and daily time series of CO, NO2 and O3, as well as a variety of meteorological variables are employed in various multi-layer percepton (MLP) models, in order to provide reliable air quality forecasts, using as a test case the city of Athens, ...

Predicting air quality in Uberlandia, Brazil, using linear models and Neural Networks

Particulate air pollution causes a wide range of effects on human health, including disorders of the respiratory and cardiovascular systems, asthma and can cause mortality. Hence, the development of an efficient air quality forecasting and early warning system is an obvious and imperative need. The objective of this work was to investigate this forecasting possibility using linear models (such as ...

PRESAXIO regional air quality modelling system: validation and applications

Different operational air quality forecasts (ESSEM Cost Action 0602) are currently available in Europe. However, most of them are not suitable for regional application and, also, their coarse outputs do not fit well with air quality management needs. In this work, PRESAXIO regional air quality modelling system is validated and applied over Galicia (NW of Spain), including WRF and CHIMERE models. ...

Using ADMS models for Air Quality Assessment and Management in China

Many cities and regions are undertaking studies of air quality in cities to determine both the current state of the environment and the effect of future economic and environmental strategies in order to manage local air quality. Often these studies are driven by legislation such as the European Union requirement to model agglomerations or the Chinese requirements to study air quality capacity and ...

Air pollution forecast in Portugal: a demand from the new air quality framework directive

This work aims at developing and validating a numerical air quality operational forecasting system that will be applied over Portugal. The CHIMERE model was chosen for the chemistry-transport simulation using the meteorological parameters supplied by the MM5 mesoscale meteorological model, forced by the AVN/NCEP global forecasts. An experiment of 48-hour real-time forecast simulations was ...

An evaluation and comparison of the various statistical and deterministic techniques for forecasting the concentration of criteria air pollutants

A statistical approach is about working through the historical data in a general way and finding guides to future behaviour. In the present study, forecasting of the criteria pollutants has been done using simple statistical techniques and attempt has been made for an inter-comparison of these techniques with various advanced statistical and deterministic techniques. The inter-comparison analysis ...

Real time, high resolution regional weather and air quality forecasting system in West Macedonia, Greece

This paper presents an overview of the University of Western Macedonia's (UoWM) operational model for predicting the prevailing meteorological and air quality conditions on a high resolution (2 × 2 km²) scale. The MM5 – SMOKE – CMAQ has been suitably parameterised with respect to the particular geographical and climatic characteristics of the region of West Macedonia. The system is designed to ...

The application of Eulerian models for air quality prediction and the evaluation of emission control strategies in Canada

The Canadian Hemispheric and Regional Ozone and NOx System (CHRONOS) has been designed for the prediction of atmospheric oxidants on both regional and hemispheric scales. The model simulates dispersion and complex chemistry of nitrogen oxides and volatile organic compounds (VOCs) using inventories of actual anthropogenic emission. The meteorological input for the model is provided by the ...

Application of adjoint CMAQ chemical transport model in the Athens greater area: sensitivities study on ozone concentrations

The factors affecting ground level ozone concentrations in the Greater Athens Area (GAA) are examined through adjoint sensitivity analysis, using a meteorology and air quality forecasting system based on MM5, the in–house EMISLAB emissions processing system and the chemical transport model Community Multiscale Air Quality (CMAQ). Sensitivities of the ground level ozone concentrations ('response ...

A modelling system for air quality management

To develop effective air quality management strategies at regional and urban levels requires the preparation of several actions belonging to different scientific areas and analysis of their complex interactions. A well-structured management system must be based on efficient tools that integrate diverse sets of information - emissions, traffic, meteorological variables and air quality data. ...

Urban ozone modelling by using a prognostic Eulerian air quality system: Madrid case study

Air quality models are essential tools in the understanding of pollutant dynamics in the urban atmosphere. In this contribution we present an air quality system (ANA), which is composed of a meteorological module that uses a three-dimensional approach with terrain-following coordinates and the non-hydrostatic approach, and a detailed emission model (250 x 250 m) that includes the anthropogenic ...

SAGA: a decision support system for air pollution management around a coal-fired power plant

Air quality models are currently feasible approaches to prevent air pollution episodes. From one of the first source-oriented modelling approaches for air pollution forecasting (Souto et al., 1994, 1996, 1998), a new decision support system for air quality management, SAGA, was developed to provide support to As Pontes Power Plant (APPP) staff. SAGA can provide air pollution forecasts and manage ...
