Ozone layer monitoring

Ozone layer monitoring involves tracking the amount of ozone gas in the Earth's stratosphere, primarily over the Antarctic, using specialized instruments like satellite sensors, ground-based spectrometers, and balloon-borne instruments. These tools measure how much ozone is present and detect changes over time. Monitoring helps scientists understand how human-made chemicals, like CFCs, impact the ozone layer and assess the effectiveness of international agreements. Accurate data allows for early detection of depletion trends, guiding policies to protect this vital layer, which shields us from harmful ultraviolet radiation.
