ozonszondák

An ozonszonda, or ozonesonde, is a device used to measure the vertical distribution of ozone in the Earth's atmosphere. It is typically launched via a weather balloon and transmits data back to ground stations. The primary purpose of ozonesondes is to gather information about the ozone layer, particularly its concentration at different altitudes. This data is crucial for understanding atmospheric chemistry, ozone depletion, and recovery processes.

Ozonesondes employ various sensing techniques. A common method involves an electrochemical cell that reacts with ozone. The resulting electrical current is proportional to the ozone concentration. Other technologies may utilize optical absorption or chemiluminescence. The balloon carries the sonde to altitudes typically reaching the stratosphere, where the majority of atmospheric ozone resides. As the balloon ascends, the sonde continuously records ozone concentrations, temperature, pressure, and humidity.

The collected data from ozonesonde launches is vital for climate modeling and atmospheric research. It helps scientists track changes in ozone levels over time, identify regional variations, and assess the impact of human activities, such as the emission of ozone-depleting substances. Regular ozonesonde campaigns contribute to international monitoring efforts and inform policy decisions related to atmospheric protection. The accuracy and reliability of these measurements are essential for long-term trend analysis and scientific validation.
