Air Quality

Using land-use and traffic assignment models to derive estimates of exposure to traffic emissions and ultrafine particles.

Urban areas face increasing challenges to manage their growth. The complexities inherent to the interrelations between urban planning, people's behaviour and the natural environment highlight the need to tackle sustainability issues in an integrated framework.

More than 30 international experts in climate science will meet in Queenstown this week to discuss implementing a new a state-of-the-art global network to improve the quality of measurements of upper air climate variables.

Over the past decade, predicting the weather, and understanding the changes in climate, has emerged as one of the most important and topical areas of scientific endeavour.

UPTECH is a world-leading observational study currently underway in SE Queensland - UPTECH-NZ is one of several related projects.

NIWA scientists say concentrations of ozone high in the atmosphere are projected to increase.

This is good news for the ozone hole over the South Pole.  However, modelling shows that, by the year 2100, ozone in the lower atmosphere could actually be a problem for New Zealand and for much of the Southern Hemisphere.

The statement made by NIWA Principal Scientist, Dr Keith Lassey in a TV3 news story about methane (22 Dec 2009) is correct.

The concentration of methane in the atmosphere is rising, according to measurements made by NIWA.

NIWA has today released measurements from its globally significant Baring Head station showing that southern hemisphere atmospheric methane increased by 0.7% over the two-year period 2007–08. While this increase may not sound like much, it is about 35 times more than all the methane produced by New Zealand livestock each year.

Presentations from NIWA’s air quality workshops are available on this page.
