Air Quality Forecasting Articles

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 ...

Air quality model for Austria: development and evaluation of ozone forecasts

An overview of the main findings of recent sensitivity studies and evaluations of ozone forecasts of the Air Quality model for Austria (AQA) is presented. Before the operational forecasts were started at the ZAMG, studies with different model input were conducted to find the appropriate model set–up. The performance of the chemical mechanisms CB–IV and SAPRC99 is shown for a hot period with ...

Air quality indexing

In an attempt to meet the public's needs for information on air quality a variety of indexes have been developed and they continue to evolve. To show the complexity and the diversity of such indices, a variety of current air quality indices are described here and compared in regard to their performance and ability to deliver quality information. A number of characteristics seem desirable for an ...

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 ...

A Time Series Forecasting of Air Pollution in Indore

Abstract. Forecasting involves the generation of a number, set of numbers, or scenario that corresponds to a future occurrence. It is absolutely essential to short-range and long-range planning. By definition, a forecast is based on past data, as opposed to a prediction, which is more subjective and based on instinct, get feel, or guess. For example, the evening news gives the weather ...

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 ...

Forecasting air quality in the Greater Athens area for the year 2004: an intercomparison of the results of four different dispersion models

Forecasts for the NOx concentration levels in the Greater Athens area in 2004 are compared to the corresponding figures for 1990. Simulations are performed for two meteorological cases using four different dispersion models. Two different emission inventories are employed in the simulations. The first is based on the conditions for the year 1990, while the second is the reference scenario for the ...

The New England Air Quality Forecasting Pilot Program: Development of an Evaluation Protocol and Performance

The National Oceanic and Atmospheric Administration recently sponsored the New England Forecasting Pilot Program to serve as a “test bed” for chemical forecasting by providing all of the elements of a National Air Quality Forecasting System, including the development and implementation of an evaluation protocol. This Pilot Program enlisted three regional-scale air quality models, serving as ...

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. ...

Studies of air quality predictors based on neural networks

In recent years, urban air pollution has emerged as an acute problem because of its negative effect on health and living conditions. Regional air quality problems, in general, are linked to violations of specified air quality standards. The current study aims to find neural network based air quality predictors, which can work with a limited number of datasets and are robust enough to handle data ...

5 Habits that are bad for your indoor air quality

School is starting, but warm weather means we are still spending more time outside and keeping windows open as much as possible. However, it doesn’t mean we are safe from poor indoor air quality at home. In fact, indoor air may be more polluted in the summer months than in the wintertime. The reasons include high humidity, pollutant buildup, pesticides and VOCs. There are certain habits in ...

Every breath you take — air quality in Europe

The characters in this story are fictional. However the data are real. The story is set on 27 July 2008 when an air quality warning was issued in Brussels. Anna is 37 years old and lives in the centre of Brussels. She and her young son Johan are planning a trip outside the busy city. Anna suffers from asthma and her doctor has warned of the dangers of air pollution, especially on hot summer days. ...

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. ...
