Air Grid: using grid monitoring to map air quality
Air quality is almost never consistent across NZ’s towns – polluted air can readily be transported on the breeze and accumulate in different locations.
Monitoring and mapping outdoor air with dense monitor gridsNIWA is a pioneer in using dense grids of new-generation air monitors to create detailed maps of air quality. We use monitors that measure particulate matter levels (PM10 and PM2.5) every 20 minutes or faster, sending data to the cloud via the mobile phone network.
These data can be converted into maps of air quality which are readily turned into maps and animations.
