Atmosphere research projects

The current method for calculating wind speed-up is inadequate, and can grossly under-predict correct design wind speeds in NZ's complex terrain.
Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.
NIWA is conducting a range of projects aimed at understanding how different emission sources and atmospheric processes lead to variations in the composition of air across our urban areas.
NIWA is exploring the potential of new technologies for monitoring and sharing air quality data.
NIWA is conducting a range of projects aimed at determining the impact that road traffic has on the quality of urban air.

How do marine micro-organisms influence the earth's atmosphere and climate?

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.
In 2004, scientists added iron salts to surface Sub-Antarctic waters east of New Zealand's South Island to determine whether this stimulated phytoplankton growth, and to examine the exchange of carbon dioxide (CO2) and trace gases between the atmosphere and ocean.
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.
The Antarctic ozone hole has a major effect on the local climate, and the future of Antarctica will influence global climate and sea level changes.

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.
