  • AQMesh used to measure local air quality at Surrey school

    Cleves School in Weybridge, Surrey (UK) has used AQMesh to measure pollution at the primary school’s entrance. The project, led by Dr. Edward Salter over the school’s summer term, aimed to understand exposure of the children (aged 7-11) to dangerous pollutant gases, with particular interest in the levels of nitrogen dioxide (NO2) and ozone (O3). Initial findings showed that levels of ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Two AQMesh pods operating across Spain for over 6 years

    Whilst not the only AQMesh pods still in regular use since the product was commercially launched in 2013, two AQMesh pods are still in use in Spain and demonstrate the long life of this small sensor air quality monitoring system. Over the last six years, the two pods have been loaned by AQMesh distributor in Spain, Envirodata, to a number of customers for trials and demonstrations, as well as ...

  • Monitoring - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • Solo flight tracks global Black Carbon

    On 8th January 2012 a tiny ultra-light aircraft left Ljubljana in Slovenia on a mission to circumvent the globe using the smallest amount of fuel per distance flown whilst recording ambient levels of Black Carbon (BC) – one of the most important measures of air quality in terms of both human health and climate change. UK based particulate monitoring specialist Jim Mills from Air Monitors ...

  • Black Carbon – the elephant in the room!

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

  • The invisible fine dust

    Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous. According to a current study conducted by the Max Planck Society, ...

  • The New England Air Quality Forecasting Pilot Program: Development of an Evaluation Protocol and Performance

    The National Oceanic and Atmospheric Administration recently sponsored the New England Forecasting Pilot Program to serve as a “test bed” for chemical forecasting by providing all of the elements of a National Air Quality Forecasting System, including the development and implementation of an evaluation protocol. This Pilot Program enlisted three regional-scale air quality models, serving as ...

  • A nested application of four-dimensional variational assimilation of tropospheric chemical data

    The chemistry transport model system EURAD-IM and its variational data assimilation module are applied to assess air quality conditions during the measurement campaign VERTIKO. The inverse modelling system has been designed to run in a nested setup, assimilating in-situ observations and measurements by remote sensing. The benefits of joint initial value and emission rate optimisation are ...

  • Volvo dealer in Sweden compares air quality indoor and outdoor - Case Study

    Two AQMesh pods were used to measure NO, NO2, O3 and CO during May and June 2017 at the largest combined Volvo, Ford and Renault car dealer in Stockholm, Sweden, located on the highway between Stockholm city centre and Arlanda airport. The objective was to measure the air quality outside and inside the combined showroom and workshop, demonstrating the importance of measuring common ...

  • Methodology for developing an air quality index (AQI) for Tunisia

    Air quality index (AQI) is a quantitative tool through which air pollution data can be reported, providing information on how clean or polluted the air is. Several countries employ some type of air quality index to communicate the quality of their air. Some of these systems rely on relating measured (monitored) or predicted concentrations of air pollutants (results of modelling system). In this ...

  • Planning for a Gas Monitoring System

    Do you need a gas monitoring system? Then you already know which gases you want to monitor, you probably have an idea of measurement ranges and accuracy requirements, and perhaps you have a budget for the system. But which other aspects have to be considered, and how do you actually design the system? ...

  • Air quality management - from traffic management to environmental traffic management

    Traffic management systems are commonly used to optimize traffic flow in urban areas, e.g. to prevent traffic congestion. However, the regulation of traffic flows can also be used to control traffic induced emissions and therefore affects air quality. To use a traffic management system as an instrument for the benefit of air quality, the application requires reliable information about the current ...
