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 ...

How the New Zealand National Institute of Water and Atmospheric Research informs policy and public health with hyperlocal air quality mapping
NIWA has pioneered the use of dense air quality sensor networks to uncover block-by-block air pollution patterns within towns across New Zealand. 40 Clarity Node-S solar-powered air quality sensors deployed 3x Higher PM2.5 levels detected in air pollution hotspots compared to cleanest areas 6 km Maximum distance NIWA deployed Clarity sensors downwind to capture pollution plumes Across New ...

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 ...

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 ...

Airparif uses Isatis to process 11 million+ mesh grids and generate daily air quality maps - Case Study
Isatis has been part of Airparif data processing workflow for 10+ years. The software is used daily to gather data and map air pollution over Paris area. The facts Airparif is part of the French AASQA network (“Associations Agréées de Surveillance de la Qualité de l’Air”). The AASQA are a French non-profit association accredited by the French Ministry of ...

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 ...

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 ...

Location for Air Quality Monitoring System Plays a Critical Role in Sensor Accuracy
Air quality is a complex, multi-faceted topic with many nuances. Air is dynamic. That means it moves continuously. And it carries its pollutants wherever it goes. So, it becomes quite difficult when it comes to monitoring the air quality of a particular ...
