<br /><strong>Updated with new data on 14 Oct 2017</strong><br />
<p>Ozone is a gas that forms a naturally occurring layer in the upper atmosphere (stratosphere), protecting Earth from the sun’s ultraviolet (UV) light. The ozone hole is an area of reduced stratospheric ozone. It forms in spring over Antarctica because of ozone-depleting substances (ODSs) produced from human activities. The ozone hole has started to shrink due to the phase-out of ODSs, and it is possible that it will cease to form by the middle of this century.<br>
The ozone hole does not have a large effect on the concentration of ozone over New Zealand. However, when the ozone hole breaks up in spring, it can send ‘plumes’ of ozone-depleted air over New Zealand. Reporting on the state of the ozone hole helps us understand the state of ozone concentrations globally.<br>

<p>NIWA supplied ozone data in two forms, with different starting dates:<br>
- measurements made using a Dobson spectrophotometer (number 72), from 1987<br>
- data assimilated from satellite measurements recalibrated against the global Dobson network, from 1978.<br>
NIWA takes measurements using the Dobson spectrophotometer 72 under clear-sky, direct sunlight conditions at Lauder in Otago. There are gaps in the time series due to days with cloud, rain, or too much wind. However, over the whole period, each individual calendar day of the year was measured. This allows us to calculate statistics based on the day of the year.<br>
The trend was assessed using the Theil-Sen estimator and the Two One-Sided Test (TOST) for equivalence at the 95% confidence level.<br>

<p>Ozone (O3) is a gas that is of interest in two regions of Earth’s atmosphere – at ground level and in the upper atmosphere (stratosphere). Stratospheric ozone absorbs ultraviolet (UV) rays from the sun and protects Earth from harmful levels of UV. Exposure to these UV rays has been linked to skin cancer. Monitoring variations in stratospheric ozone concentrations is important in New Zealand as we have high rates of skin cancers.<br>
Ozone data for Lauder have been supplied in two forms: Measurements taken with Dobson spectrophotometer (number 72) and data assimilated from satellite measurements recalibrated against the global Dobson network. The Dobson spectrophotometer has been in operation at Lauder since January 1987. The timeseries for interpolated satellite data is available from 1978. Both timeseries are provided until 2013.<br>
This dataset is the assimilated dataset which is available from 1978 to 2013. Measurements are in Dobson units (DU). One DU represents the amount of ozone molecules needed to produce a 0.01mm layer of pure ozone.<br>
