Domestic wood burners are a major source of air pollutants in many of New Zealand's urban areas during winter, with smoke levels influenced by the weather, topography, buildings and home-heating behaviour.
This research project focusses on modelling atmospheric chemistry and climate from the surface to the top of the stratosphere, using sophisticated chemistry-climate models.
NIWA participates in the Total Carbon Column Observing Network, a ground-based observing network dedicated to making precise and accurate measurements of greenhouse gas concentrations in different parts of the atmosphere.
This research aims to provide better predictions of changes in the ocean and climate system, particularly the way in which the ocean around New Zealand regulates greenhouse gases and clouds.
This project aims to estimate emissions of the greenhouse gases methane (CH4) and nitrous oxide (N2O) from New Zealand's pastoral farming systems, and to estimate the effectiveness of different approaches to reducing these emissions.
By analysing air trapped in ancient ice we can see how wetlands and permafrosts responded to warming periods in the past, and help predict what will happen in the future.
CFCs have damaged the ozone layer and led to higher UV levels and increased health risks. Our role is to understand the causes and effects of ozone depletion, to inform the public of the risk.
