The Use of Real-Time Air Quality Data in Daily Forecasting and Decision-Making
The feature articles published in this month’s issue describe various near-realtime data resources and provide examples of how they are being used to facilitate air quality forecasting and daily decision-making. The articles reinforce the importance of making as much environmental data as possible available to the public in real time. The major national source of realtime air quality ...

Buying AQM Equipment or AQ Data? It’s Your Choice
In the traditional approach to air quality monitoring, those “who wants to know” have also owned and maintained the monitoring equipment generating the answers. This approach worked quite fine as long as the user had the budget to invest in the equipment and an organization large enough to maintain it. However, recent years’ slimmed organizations have opened up for an ...

Air Quality Data: How good is your validation?
Low-cost sensor technology is key to realising the many commercial applications of passive air quality monitoring. Why then has it not yet been adopted more widely? The biggest challenge for low-cost air quality products is to operate accurately in the field. However, there remains some mistrust of low-cost sensor systems amongst potential users. It's well known that they can track changes in ...

Interaction between air pollution and meteorological parameters in Erzurum, Turkey
In recent years, the rapid increase in population density has caused increases in the consumption of fuel, and the outdoor air quality has deteriorated in the crowded urban areas of Turkey. Erzurum, a city in the eastern part of Turkey, is influenced by air pollutants such as SO2 and suspended particles. It is known that, in general, the air pollution concentrations have a close relationship with ...

Receptor modelling of air quality data using neural networks
Introduction According to Hopke (1991) the management of ambient air quality is a difficult but important problem. In general, it involves the identification of the sources of materials emitted into the air, the estimation of the emission rates of the pollutants, the understanding of the transport-diffusion processes involved and the physical and chemical changes that can take place during the ...

Investigating weekend air quality observations with the aid of Fourier analysis in Athens, Greece
Weekend air quality is analysed with the aid of Fourier analysis, in order to reveal time-series structures for Athens, Greece. For this reason, an appropriate analysis of a 10 year record from 1990–1999 of air quality data from the monitoring network in Athens is carried out for two specific monitoring sites. The aim of the paper is to investigate the temporal pattern of observations in order to ...

Dispersion models and air quality data for population exposure assessment to air pollution
Evaluating the extent of exposure to chemicals in absence of continuous measurements of their concentration in air and direct measures of personal exposure is crucial for epidemiological studies. Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. However, they cannot easily be applied to short-term epidemiological ...

Ozone diurnal characteristics in areas with different urbanizations
The influences of the levels of urbanisation over the tropospheric ozone in the Hong Kong Special Administrative Region (HKSAR) have been analysed using its long–term air quality data from 1990 to 2005. Urbanisation was found to have considerable influence on ozone diurnal variations. Different ozone diurnal patterns would be formed under various land uses which are categorised as rural, ...

Why cities need higher resolution air quality data to plan for climate change
TL;DR - As global urbanization continues and cities account for a greater portion of the world’s population, so too do they become responsible for more climate and air pollutant emissions. Cities across the globe currently suffer from disproportionately poor air quality and face the consequences when it comes to public and environmental health. As climate change accelerates and leaves ...

Monitoring air quality in residential buildings and offices - Case Study
Air quality is one of the key challenges of smart buildings today. We spend 80% of our time indoors, which is why understanding your air quality is crucial not only for your health but also to enhance the value of your infrastructures. VINCI, a French leader in concessions and construction companies, decided to install IoT networks to continuously monitor the indoor comfort of their ...

Reporting and exchanging air quality information using e-Reporting
A number of EU legal instruments require EU Member States to monitor and report air quality data. This information is collated, analysed and disseminated by the European Environment Agency (EEA). At present much of the data is reported electronically by countries in data flows required under a specific legal instrument. As a result, reporting on air quality is not always integrated across all ...

USA Institute Monitors Air Quality for Cultural Artefact Storage
The Image Permanence Institute (IPI) at the Rochester Institute of Technology (RIT) is deploying 11 Praxis/Urban devices as part of a three-year research project on the impact of energy saving strategies on air quality (i.e. temperature, humidity and pollutant levels) in collection storage spaces. The Image Permanence Institute works to support the preservation of cultural heritage collections ...

Effects of meteorological parameters on RSPM concentration in urban Delhi
The adverse effect of Respirable Suspended Particulate Matter (RSPM) has become a well-recognised problem in environmental science. Dispersion and dilution of air pollutants are strongly influenced by meteorological parameters, namely wind, turbulence, and atmospheric stability. The analysis of Delhi's air quality data shows that winter is the most critical season with respect to the ...

Developments in ADMS-Airport to take account of near field dispersion and applications to Heathrow Airport
ADMS-Airport is based on the ADMS-Urban system for modelling urban air quality. In the near field it employs a quasi-Gaussian dispersion model and this is nested within a trajectory model. Aircraft sources are treated explicitly as accelerating jets. Application of the model to air quality calculations was conducted for the Model Inter-Comparison (MIC) Study of Project for the Sustainable ...
