Keflavik airport tunnel case study using 5 AQMesh air quality monitoring pods to measure gases produced by the nearby volcano
Key benefits of AQMesh
Featured case studies
Breathe London case study using 100 AQMesh air quality monitors across London as the world's first hyperlocal air quality monitoring network
Minnesota Pollution Control Agency case study using 50 AQMesh pods across the twin cities of Minneapolis - St. Paul to create a network of air quality monitoring stations across the region
Marseilles tunnel case study using 8 AQMesh air quality monitoring pods to trigger in-tunnel ventilation systems
Nicaragua volcano uses 6 AQMesh pods to measure emissions of SO2 around the local communities
Newcastle University case study using 55 AQMesh pods across Newcastle and Gateshead as part of the Urban Observatory project
Latest news
The two pods were used as part of a year-long study into the health risks taken by people using open spaces in the cities for physical activity, measuring NO, NO2, O3, CO, CO2, PM2.5, PM10, pressure, temperature and relative humidity.
Hyperlocal air quality monitoring promises to fill in the gaps between sparse reference stations – great, lots more measurements. And each of your lovely small sensor monitoring stations can measure a dozen or more pollutants and environmental conditions – even better. Or is it?
Central to the report is the position that “air quality monitoring is the first step for understanding a population’s exposure and taking action” and the report lays out clearly the monitoring methodologies available, from passive sampling to modelling.
The Behavioural Enhancement for Air Improvement and Resilience (BEAIR) concept integrates smart lighting, intelligent cameras and AQMesh air quality monitors at pedestrian crossings, as well as an app that offers real-time information on air quality and local traffic.
Generally, the limiting factor will be budget. The clue is in the name with hyperlocal air quality monitoring, and pollution levels can vary hugely over short distances. NO measurements around streets, for example, are often significantly different from one side of the road to the other, particularly if there isn’t much wind and/or a street canyon effect.
Monitoring H2S in air at levels of less than one part per billion – well below the level at which the human nose can detect this odorous and harmful gas – AQMesh can be used both to measure very dilute levels and where concentrations are significant.
Proven results
AQMesh is the only small sensor air quality monitoring system that can demonstrate its performance across extensive global co-location comparison trials now spanning more than 10 years. AQMesh pods have been operating out in the field since 2012 next to certified reference equipment, in real applications, in real conditions, across all environments, throughout all seasons, for months rather than weeks or days.
Six month co-location comparison trial of PM2.5 in London, UK shows R2 of 0.91
Two month co-location comparison trial of NO2 in Minnesota, USA shows R2 of 0.94
One month co-location comparison trial of O3 in Southern USA during summer shows R2 of 0.92
Two month co-location comparison trial of PM10 in Slovakia shows R2 of 0.92
