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 ...

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 ...

A decision support system for air quality management combining GIS and optimisation techniques
This paper describes a multi-tiered approach to the design of plans and policies for urban environmental management, in particular air quality, as related to the energy and transportation sectors. The approach is based on the iterative combination of sectoral and global optimisation models, including a discrete multi-criteria approach, and spatially distributed air quality models. The approach ...

Development of air quality indices for Mumbai, India
This paper proposes a simple approach for developing air quality indices for different sites in an urban region of India. The database used for calculating these indices included various physical and chemical characteristics of suspended particulate matter, such as particle size distribution, chemical (elemental) properties and parameters governing the acidity of precipitation. The indices were ...

Particle reduction plans in Europe - Implementation of the first daughter directive on ambient air quality in Europe
This publication analyses the quality of national implementation of the first Air Quality Daughter Directive (1999/30/EC). The report is based on information from 15 NGOs (members of the EEB’s Clean Air Working Group), who provided data for PM10 concentrations in ambient air as well as information about air quality management plans from 30 cities in Europe. The air pollution challenge ...

Using Rn-222 to manage the air quality of air conditioned buildings in Hong Kong
This paper proposes a pragmatic methodology to manage the air quality of an air conditioned building as well as optimizing energy consumption during venting. Radon-222 (Rn-222) is used as a tracer to quantify the specific production rates and resultant losses of pollutants for which the information is important in indoor air quality management. A term, indoor pollutant inventory, is introduced ...

Review of the requirements for models and model applications
Requirements for models and model applications are reviewed on basis of the Dobris Assessment report and the practice in EU legislation and international organisations, and from the responses of a questionnaire sent to 38 European countries. Model applications are frequently used for regulatory and general assessment purposes by various users (scientists, air quality managers, policy-makers). ...

Particle reduction plans in Europe - Implementation of the first Daughter Directive on Ambient Air Quality in Europe
Untitled Document IMPLEMENTATION OF THE FIRST DAUGHTER DIRECTIVE ON AMBIENT AIR QUALITY IN EUROPE INTRODUCTION AND EXECUTIVE SUMMARY This publication analyses the quality of national implementation of the first Air Quality Daughter Directive (1999/30/EC). The report is based on information from 15 NGOs (members of the EEB’s Clean Air Working Group), who provided ...

Air Quality Monitoring
Why monitor air quality? Well, to monitor is to know. Everything else is just more or less qualified guesses. International, national and local air quality targets and limits are also tied to monitoring results. What is Air Quality? How is air quality characterised? It is quite common to find air quality indexes, where the ranges are divided in sections indicating “good”, ...
