<p>Ground-level (tropospheric) ozone (O3) exists at a natural background level but is also produced when nitrogen oxides (NOx) and volatile organic compounds from vehicle emissions, petrol fumes, industrial processes solvents, and other human-made sources react in the presence of heat and sunlight. It is the primary component of photochemical smog. Ozone also occurs naturally in the stratosphere, where it protects us from ultraviolet radiation – this ozone occasionally can mix downwards to ground level.</p>
<p>Ozone is a colourless, odourless gas. Exposure to high concentrations of ozone can cause respiratory health problems and is linked to cardiovascular health problems and increased mortality. Those most at risk include people with asthma, children, older adults, and people who are active outdoors, such as outdoor workers. People with certain genetic characteristics and nutrient deficiencies are also at greater risk from ozone exposure. Ozone can also affect sensitive vegetation and ecosystems and can cause damage during the growing season.</p>
<p>This dataset reports on the seasonal trends assessed for the period 2011-2020.</p>

<p>Ground-level (tropospheric) ozone (O3) exists at a natural background level but is also produced when nitrogen oxides (NOx) and volatile organic compounds from vehicle emissions, petrol fumes, industrial processes solvents, and other human-made sources react in the presence of sunlight. It is the primary component of photochemical smog.<br>
Ozone also occurs naturally in the stratosphere, where it protects us from ultraviolet radiation – this ozone occasionally can mix downwards to ground level.<br>
Because sunlight and warmth are required for the chemical reactions that form ground-level ozone, peak concentrations often occur in summer when daylight hours are longer and temperatures are higher. Since the precursors for ozone can travel downwind from their sources before they react with sunlight, ozone concentrations can be high many kilometres from the precursor emissions’ sources.<br>
Exposure to high concentrations of ozone can cause respiratory health problems and is linked to cardiovascular health problems and mortality. It can also damage vegetation.<br>

<p>Ozone occurs in two regions of Earth’s atmosphere – at ground level and in the upper atmosphere. Ground-level ozone is a gas formed by chemical reactions involving sunlight, volatile organic compounds, and nitrogen oxides (the main source being vehicle emissions). It is linked to increased health risks, such as respiratory and cardiovascular diseases. </p>
<p>Given the time required for the chemical reactions that form ozone to take place, high concentrations of it occur well away and downwind from where the pollutants are initially emitted. </p>
<p>Column headings:<br>
- Con_mcg_m3 = Concentration in micrograms per cubic metre (μg/m3) </p>
<p>This dataset relates to the "Ground-level ozone concentrations" measure on the Environmental Indicators, Te taiao Aotearoa website.</p>
