Current climate models misrepresent cloud formation over the Southern Ocean causing mismatches between models and satellite observations. These errors are important because too much sunlight reaches the ocean surface in simulations, leading to overestimates of ocean...
The degree to which road traffic pollutes urban air varies hugely, depending how much traffic is nearby. We’ve been mapping traffic pollution in detail across all New Zealand’s towns and cities over the last decade. In doing so we’ve been refining the methods to...

The COVID-19 pandemic has challenged the status quo in a number of ways. From helping the world realize that you can run scientific conferences that are accessible for people who cannot (or will not) travel, to rising the very thorny question of "should kids be...
Chasing the dream of accurate and reliable low cost sensors in air qualityFor quite a few years now, there are a number of projects around consumer level (as opposed to research grade) air quality sensors. (Air Quality Egg, Speck, Dustduino, Air Beam and our own...
Using solid fuel Use of solid fuel, mostly wood but also coal, particularly in some South Island towns, is a major source of night-time airborne pollution in many places in New Zealand. On cold, still winter nights dispersion is poor and emissions from domestic...
So what is air pollution? Pollution is bad. The word ‘pollution’ conjures up images of something dark, something menacing, something nasty that turns up where it shouldn’t. The notion of something clean and pure being invaded by something repulsive or distasteful that...
Many teachers know that period 3 brain fog, when the children in front of them slump their shoulders and everything seems harder. It could be stale air. Without good ventilation contaminants can build up, including other people’s breath. And that breath could contain...
WestConnex: Using monitoring data to understand the impact of new road tunnels on local air quality Major road tunnels are designed to meet consent conditions that minimize their impact on local air quality. But how can communities be assured they are meeting these...
Community Air Action: Air quality solutions for homes and communities, and the means to evaluate them Putting another log on the fire keeps many New Zealanders warm on winter nights. But the smoke it creates pollutes many of our towns, causing regular breaches of...
