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 ...

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 ...

Applied comprehensive NO2 and particulate matter dispersion modelling for Switzerland

This paper presents the NO2 and Particulate Matter (PM) dispersion modelling for the whole of Switzerland. Air quality maps are computed for the year 2000 and future years. Future developments like the EURO-4 legislation on motor vehicles are taken into account. For all major source groups (road traffic, off-road traffic, industry, households, etc.), separate countrywide emission inventories with ...

Synergetic use of TERRA/MODIS imagery and meteorological data for studying aerosol dust events in Cyprus

This paper presents the results from the analysis of TERRA/Moderate Resolution Imaging Spectrometer (MODIS) images for the detection and mapping of particulate air pollution in Cyprus. For this purpose, a set of selected air pollution events for the year 2002 was used, mainly associated with dust transported over the area from the surrounding deserts. The results depict the potential of the use ...

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 ...

Breathing Dirty Air is A Latent Danger

Air pollution from wildfire smoke and lots of other sources is, unfortunately, a developing trouble around the world. The World Health Organization lately stated that 9 out of 10 people breathe polluted air and that 7 million people die every year due to it. At the country level, India has some of the worst air worldwide. In fact, 11 of the 12 highest levels cities are in India. The ozone, ...

The Kansas City, Missouri, Ground-Level Ozone (GLO) Project: A Community-Based Air Pollution Field Experiment

Tropospheric ozone concentrations for Kansas City are well known on a regional scale. The Kansas City, Missouri, ground-level ozone (GLO) project measured outdoor ozone concentrations using passive sensing devices (PSDs) on a neighborhood scale. Highly resolved exposure maps were made based on the detailed air quality observations collected during the seven week sampling study during the summer ...

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 ...

Dispersion model input parameters from numerical weather prediction or synoptic observations

Regulatory dispersion modelling uses hourly synoptic observations (OBS) from a nearby station. Alternatively, hourly Numerical Weather Prediction (NWP) data are useable in air quality management. In parallel runs, OBS data and NWP (two grid scales, ∼60 km and ∼12 km) were input to the meteorological pre–processor of the Met Office NAME III dispersion model. Frequency distribution results for ...

Urban air quality sensors: More information, better quality of life in cities

The city of Donostia-San Sebastián seeks to make the most of all the advantages derived from ICT technologies. From an air quality perspective, the periods of high pollution are unusual, since its coastal location facilitates the dispersion of pollutants. This city holds a network of 6 monitoring stations which belong to the Basque Government Air Quality Network, which ...

Carbon Dioxide Measurement

What is Carbon Dioxide? Carbon Dioxide (CO2) is a chemical compound that is an odourless colourless gas at room temperature. The compound consists of one carbon atom and two oxygen atoms. Carbon dioxide enters the atmosphere through a number of ways; it is released by the exhaling of organisms and it is given off through the combustion of matter. Plants also take in Carbon Dioxide through the ...
