UV and ozone

NIWA's Atmospheric Research Station at Lauder in Central Otago specialises in measuring CFCs, ozone, UV levels and greenhouse gases and has a wide range of world-class instruments and research scientists.

This is the home for NIWA's UV and ozone research, including maps and graphs showing daily predictions and measurements for UV levels across New Zealand.

Plots of today's UV index are available in graphical form for Auckland, Wellington, Christchurch, Lauder and Invercargill.

The Antarctic ozone hole typically reaches its greatest extent in September or October and disappears in November or December.

New research suggests large-scale wildfires may be changing the chemical makeup of our atmosphere. Jessica Rowley explains.

Experts are warning Kiwis to be extra cautious this summer, with ultraviolet (UV) radiation levels averaging higher compared to 2021.

Smoke from the devastating Australian wildfires impacted the atmosphere in a way that’s never been seen before.

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 blob of smoke from the Australian bushfires is continuing to circle the globe almost four months after it formed.

On the eve of the 30th anniversary since the Montreal Protocol came into force, new research by NIWA scientists reinforces its reputation as the world’s most successful environmental treaty.
