A method for mapping the air pollution in cities with the combined use of measured and calculated concentrations
The aim of this paper is to develop the technique for mapping the air pollution in cities using measured and computed concentrations. It is based on the combined use of deterministic and stochastic modelling. Two different approaches are applied to extrapolate the measurements to the regular grid points covering the city. The first uses the method of the principal components, and the second is ...

Real-time pollution maps for Smart Cities
Massive-scale urbanization, industrialization, and population growth along with an increase in vehicular traffic and energy use have made urban air quality a global concern. The distribution of air pollution concentration over a large urban area predominantly depends on local emission sources and atmospheric flow conditions. Also, smart cities are the centres of various activities having ...

Spatial mapping of the city of Lisbon using biomonitors
Biomonitoring is used to study the performance of a single air sampler as representing air elemental concentrations in Lisbon. A database of chemical elements' concentrations was obtained by analysing exposed lichens and bark, hung on courtyard trees of 22 Lisbon basic schools from January to May 2008 and June to October 2008 (winter and summer campaigns). Electric conductivity was also measured ...

Festival music never sounded so good
Jochen Schaal, Managing Director at SoundPLAN GmbH – a market leader in sound and air pollution mapping software – looks at the developments in understanding and mitigating nuisance noise at open air events. Introduction Music festivals have been popular for decades, with millions of attendees across the globe at events such as Lollapalooza in Argentina and Chile, Glastonbury in ...

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 ...

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 ...

Monitoring with the use of passive samplers ? a useful source of information for the mapping and modelling of urban atmosphere pollution
Due to human activities, increasing numbers of harmful substances are emitted into the atmosphere; they are recognised as potentially dangerous to living organisms, mainly because of their toxicity. Among others, compounds from the BTEX group, e.g. benzene, toluene, ethylbenzene and xylenes, are considered as such toxic substances. They are present in the air above urbanised as well as rural ...

Noisy sites setting alarm bells ringing?
Industrial sites such as refineries and factories will always be noisy, but with millions of people across the world occupationally exposed to hazardous noise, and noise-related hearing loss listed as one of the most prevalent occupational health concerns, what can be done about it? Arne Berndt, owner / adviser at SoundPLAN GmbH and SoundPLAN International LLC – a market leader in sound and ...

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 ...

Assessment of regional air pollution distribution by point cumulative semivariogram method at Erzurum urban center, TURKEY
In the assessment of air quality, regional distribution and dispersion with distance are important, together with the variations of pollutants in time. On this occasion, the point cumulative semi-variogram (PCSV) method is used in order to find simply regional distribution of pollutants of Erzurum urban centre. This method is based simply on the summation of square differences in air pollutant ...

A holiday from noise pollution
A holiday from noise pollution Tourism is one of the fastest growing economic sectors in the world and offers significant benefits, but among the many challenges the industry faces is protecting the local population, environment, and the travellers themselves, from excessive noise. The modes of transport (especially planes and cars) and mass arrivals at airports, railway stations, and ports and ...

Effects of Wildfires on ambient air quality
A thick dark blanket of smoke covers the cities, as fires engulf the forests. Globally, wildfires have drastically increased in the last couple of years. Due to the changing climate with a warmer world, wildfires have become more and more frequent. Last year, the world witnessed major wildfires across the world. From Australian bushfires and California wildfire to the forest fire in Similipal, ...

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 ...

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 ...

How to improve air quality in a city: from measurement to action
Improving ambient air quality is core to the mission of local decision makers: it is both a public health and environmental issue. The challenge is quite a tall order: outdoor air pollution causes millions of premature death worldwide, and in 2021, 91% of the world population is living in places where the World Health Organization (WHO) air quality guidelines levels are not met1. Finding ways to ...

Model output data integration using a Web Map Server
Maps are one of the basic products that can be created from numerical model output data. Whether numerical weather prediction models, air quality photochemical models, air dispersion models, wave models or any other, it is useful to show in a map different fields like the air temperature, wind speed and direction, pollutants concentration, significant wave height or any other variable obtained ...
