  Oct. 22, 2019

  For the whole of my professional career, I have been using electronic based gas analysers. I was shown how to use ‘Orsat type’ chemical instruments but found them unreliable and not that user-friendly. The first instruments I used regularly were to analyse oxygen and CO, which are the most important for safety and combustion efficiency. That is still the case today, however oxides of nitrogen and sulphur are now also important from an emissions perspective. The first gas analyser that I had with %O2,...

• AQMesh Measures Influence of Cruise Ship Emissions on Local Air Quality

  Nov. 22, 2018

  AQMesh has been used in a project at the Port of Kiel, Germany, to measure emissions of nitrous oxides (NOx) and fine particulate matter (PM) around its cruise ship terminal. This year the port attracted 166 visits by 33 different cruise ships, bringing a record breaking 600,000 visitors into the city. Emissions from the cruise ship terminal and its impact on the local air quality has been in discussion for some time, as the city’s references stations indicate that nitrogen dioxide (NO2) levels regularly...

• Detailed ADMS-Urban modelling for Greater Manchester`s Clean Air Plan

  Nov. 8, 2018

  Greater Manchester is developing a Clean Air Plan to tackle illegally high levels of roadside air pollution across the city-region. They have carried out detailed modelling with CERC`s ADMS-Urban software, which is widely used for developing and testing policy and action plans for air quality improvement. The modelling identified 152 stretches of road likely to have levels of NO2 in breach of legal limits beyond 2020 if no action is taken (i.e. annual average above 40 μg/m3). An interactive mapshows which...
