  • Profile: Wills Dobson - small town, huge horizons

    Feature story
    If it wasn't for a damaged shoulder, Wills Dobson wouldn't be launching weather balloons or fixing high-precision atmospheric measuring instruments.
  • Tiny air bubbles reveal new information about greenhouse gas emissions

    Media release
    Sitting at the surface of Taylor Glacier in Antarctica, are layers of ice more than 10,000 years old. And trapped inside those layers are bubbles of ancient air – like tiny time capsules - able to tell scientists a story about what the world used to be like and how humans have changed it.

    What are greenhouse gases?

    Greenhouse gases are atmospheric gases that intercept long-wave (mainly infrared) radiation emitted from the Earth's surface.
  • NOAA Satellite data

    Like the GMS satellite, the NOAA Series of polar orbiting satellites (operated by NOAA, the US National Oceanic and Atmospheric Administration) are a component of the World Weather Watch meteorological satellite network.

    Real-time UV Index displays

    NIWA has developed a real time UV display in consultation with the Cancer Society and Sunsmart. The first prototype is currently installed at the new Molyneux Aquatic centre in Alexandra.

    UV Index Information

    The UV Index is a measure of the intensity of UV radiation. The larger the number, the more intense the UV. In New Zealand, its maximum summer value is generally about 12, but it can exceed 13 in the far North. In winter it reaches peak values of 1 or 2. Values of 10 or more should be considered as "extreme". At high altitude tropical sites (eg Mauna Loa Observatory, Hawaii), the UV Index can exceed 20.The UV Index supersedes the idea of "Time to Burn" or "Burn Time", which has been used previously in New Zealand.
