NIWA is looking at the long-term effects of motorways and wood smoke on air quality. Scientists are assessing the impacts of Auckland’s southern motorway on air quality in a surrounding neighbourhood. They are doing this to understand more about the health effects of air pollution.

New Zealand science is taking a global lead in assessing techniques for the mitigation of pastoral greenhouse gas emissions.

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 HIAPER jet recently flew very low over NIWA’s atmospheric climate research station at Lauder. The international mission is taking a slice of the atmosphere, so scientists can learn more about greenhouse gases globally.

New research by NIWA into the risks and health benefits of UV radiation has given scientists a better understanding of the health risks and possible benefits of sun beds.

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.

Pole-to-pole flights provide a global picture of greenhouse gases: this month a team of international scientists will fly from the Arctic to the Antarctic aboard an exceptional jet.

NZ scientists endured the dark polar winter to find what drives the dramatic growth of sea ice

NIWA and IBM today announced a multi-million dollar partnership where NIWA will purchase one of the world’s most powerful supercomputers for use in environmental forecasting.

The "Carbon Workshop 2008: Global Cycle to Regional Budget" will be held at the National Library Auditorium, Wellington on 14 and 15 April 2008.

A high-powered scientific panel will be meeting in Alexandra next week to consider the environmental effects of ozone depletion.

It may be a massive new car carrier, but the TransFuture 5 is also a platform for scientific research into atmospheric pollution across the Pacific.

A paper to be published in the prestigious science journal, Nature, this week offers a rare piece of good news on climate change but signals that the atmosphere may be more variable than previously suspected.

The ozone hole over Antarctica appears to be about 20% smaller than last year’s record-breaking ozone hole.

The number of scientists in New Zealand gets a temporary boost this week with the arrival of almost 400 experts in atmospheric chemistry.

That is just one of many issues scientists, industry, and government representatives will discuss at a workshop on climate change and greenhouse gases in Wellington on Thursday and Friday this week.

Recent analysis of satellite-based measurements by NIWA scientists shows that record amounts of ozone were destroyed over Antarctica in September this year.

Measurements by NIWA staff at Scott Base, Antarctica, confirm reports of a large ozone hole this year.

Christchurch has a severe air pollution problem, especially during winter. This winter, scientists from NIWA will be using a $150,000 spectrometer to examine how this local air pollution reduces the amount of UV radiation that reaches the earth’s surface.
