Towards uncertainty mapping in air-quality modelling and assessment

The aim of this paper is to promote the use of uncertainty mapping when spatial assessments of air quality are made. A large number of air quality maps are produced for scientific and policy purposes but rarely are corresponding maps of their uncertainty included. The need for such maps and the methods to produce them are described. Several uncertainty parameters are discussed but it is ...

Mapping Quality Assurance Requirements for Continuous Mercury Monitoring Systems

The Clean Air Mercury Rule (CAMR) requires coal-fired electric power plants to install and operate mercury continuous monitoring systems by December 31, 2008 such that they will have 12 months of “submittable” data by 1 January 2010. For all practical purposes, “submittable data” are “quality-assured data” that meet the extensive quality control requirements cited in the various regulations that ...

Determination of compliance with UK and EU air quality objectives from high-resolution pollutant concentration maps calculated using ADMS-Urban

The main features and functionality of the urban air quality version of ADMS (ADMS-Urban) have been presented at previous Harmonisation Workshops. The system has now been set up and applied to air quality management, decision support and air quality forecasting in a number of major cities in Europe and beyond, including London. Key recent developments of the system include a regional chemistry ...

Cartography for air quality monitoring: the geostatistical approach

Being able to provide quick and accurate pollutant maps from readings at isolated measurement stations is becoming more important today in light of the European norms on air quality and the public’s demand to be informed. Commonly used algorithms for cartography are quick but their accuracy remains to be determined.Firstly, the choice of method is arbitrary and based on user’s subjective ...

Automatic Ozone Mapping in France with ISATIS

In France, air quality data are acquired by associations in charge of the air quality monitoring (Agences Agréées pour la Surveillance de la Qualité de l’Air - AASQA) These associations use the automatic procedures of ISATIS to daily update the pollution maps they publish on their websites. These automatic procedures make use of batch and allow to save time in the cartography because they enable ...

Rough set-based regionalisation in air quality monitoring

Regionalisation is to organise a large set of spatial objects into spatially contiguous regions despite optimising the homogeneity of the derived regions, while representing social and economic geography. To confront this problem, it is necessary to classify the regions to form groups that are homogeneous in air quality attributes. It is to develop a system that applies data mining techniques to ...

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 ...

The Google Earth tool for studying Air Quality

Any person involved in air quality studies knows that cartographic representation of data (input, output or measured) is very important, time consuming and, most often, difficult. One of the difficulties is to find a suitable cartographic base over which the information (sources, sensible receptors, buildings, isopleths, etc.) must be represented. Sometimes the cartographic base is available, but ...

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. ...

MapAtWork - an efficient tool for making contour maps for workplaces

General purpose interpolation software has an overkill of functionality for making a simple contour map based on measurements. MapAtWork and NolseAtWork software will significantly reduce the time you would normally spend on getting your maps done. The Bio plotter I started at DGMR in 1981 as acoustic consultant. At that time there was no software available for making nice ...

Biomonitoring of air quality employing in situ Ramalina celastri in Argentina

The lichen Ramalina celastri was employed as an in situ biomonitor for the study of air quality and heavy metal distribution in the central region of the Argentine Republic. The thallus content of copper, iron, manganese, cobalt, zinc, nickel and lead was determined by atomic absorption spectrophotometry. Pigments, hydroperoxy conjugated dienes, malondialdehyde and sulfur were also measured. Some ...

Combination of measured and modelling data in air quality assessment in Spain

This paper describes a methodology to combine measurements from air quality stations and estimates from the CHIMERE model for air quality assessment in Spain. The methodology consists of using linear regression and kriging interpolation to correct the model results, improving the fit to the observations. It was separately applied to rural and urban conditions, giving rise to maps for each case, ...

High resolution maps of nitrogen dioxide for the Province of Styria, Austria

Knowledge about the spatial distribution of NO 2 concentrations is beneficial for setting up air quality measurement plans, assessing exposure, or in licensing procedures, where background concentration levels are required. Styria (16.400 km², 1.2 million population) is the second largest province in Austria. In order to take topographical effects on the pollutant dispersion into account, wind ...

Air quality assessment in the European Mega City Ruhr Area and effects of low emission zones

The Ruhr area is the biggest German megalopolis, a conglomerate of several intertwining major cities, with more than 5.3 million inhabitants. In spite of many efforts in recent years to improve the air quality in the Ruhr area, especially residents in street canyons with a high traffic density are still exposed to poor air quality and meeting the limit values of European air quality guidelines ...
