NIWA scientists are predicting that this year’s ozone hole will stay around for longer than usual, potentially lasting into early summer.
NIWA’s Principal Scientist - Atmosphere and Climate, Dr Olaf Morgenstern, says this is largely due to a combination of climate change and the 2022 Tonga volcanic eruption.
MethaneSAT is New Zealand’s first official government-funded satellite mission. The core mission of this unique satellite is to support reductions in methane emissions around the world.
By day Penny Smale is a mum to two young boys, living on a rural property in the middle of a farming district in Central Otago. By night, she leaves home, walks the short distance to what is essentially a large outbuilding in a paddock, and fires lasers into the sky. Penny operates a Lidar (Light Detection and Ranging) instrument at the Lauder research station in Central Otago. Essentially, she fires lasers into the sky and uses a telescope to measure what comes back.

One of the best ways to reduce the likelihood of Covid-19 being transmitted in Aotearoa New Zealand classrooms is simply by opening doors and windows to create natural ventilation, say NIWA air quality experts.
Without the global CFC ban we’d already be facing the reality of a “scorched earth”, according to researchers measuring the impact of the Montreal Protocol.
For a small group of unassuming buildings nestled amongst the wide-open spaces of the Maniototo, the Lauder Atmospheric Research Station punches well above its weight.
A NIWA-led collaboration is seeing atmospheric measurements taken from Antarctica’s Ross Island added to a highly respected international climate data reference network.
A new international study using ancient swamp kauri from Northland shows a temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts leading to global environmental change and mass extinctions.
Some of the most striking images of lockdown around the world have been the blue skies of cities ordinarily choking in smog. From New Delhi to Los Angeles, Beijing to Paris, the changes were so remarkable they were visible from space.
NIWA scientists have set up air quality sensors every 100 metres across Arrowtown in what is believed to be the world’s densest air monitoring network.
In week 3 levels of oxides of nitrogen (or NOx, representing mainly vehicle exhaust pollutants) in our major cities fell even further, with reductions of 83 – 91 % relative to normal at most sites.
