NASA Ozone Watch: 2021 Antarctic OMPS and MERRA2 Ozone

· Chlorine gases react on the surface of these PSCs to release chlorine into a form that can easily destroy ozone. The chlorine and bromine chemical catalytic reactions that destroy ozone need sunlight. Hence, the ozone hole begins to grow as the sun is rising over Antarctica at the end of the winter. The ozone hole begins to grow in August and reaches its largest area in depth from the middle ...

NASA Discovering the Ozone Hole: QA With Pawan Bhartia

One of those instruments was an ozone sensor. Since then about a dozen instruments on different satellites – improved versions of that original instrument – have flown, giving us a nearly continuous measurement. They measure the ozone very high, primarily around 16 miles (25 kilometers) up. That''s the ozone important for essentially soaking up the UV light from the sun that can cause skin ...

Nasa Ozone Watch: Ozone hole facts

Using the daily snapshots of total column ozone, we can calculate the area on the Earth that is enclosed by a line with values of 220 Dobson Units (the white line in the figure below). The ozone hole is the region over Antarctica with total ozone of 220 Dobson Units or lower. This map shows the ozone hole on October 4, 2004. The data were acquired by the ...

Evaluation of Emerging Air Sensor Performance | Air Sensor ...

· CairClip (ozone) The sensor pulls in a controlled air flow, which passes over a single electrochemical cell that responds to both nitrogen dioxide (NO2) and O3. To isolate one pollutant or the other, a separate measurement is needed in field tests. In laboratory tests, one gas type is introduced to test the sensor response. The sensor device is miniature and designed for either portable use or ...
