South Korean Stations Join Global Ozone Observation Network

South Korea's atmospheric monitoring capabilities have been significantly enhanced with the inclusion of two key stations into a global ozone observation network. The National Meteorological Science Institute announced that the Anmyeondo and Jeju Gosan Global Atmosphere Watch Centers have officially joined the EUBREWNETEU, an international network dedicated to monitoring atmospheric ozone levels across the globe.

Ozone, a molecule composed of three oxygen atoms, plays a critical role in the Earth's ecosystem. While harmful as a pollutant near the surface, stratospheric ozone forms a vital layer that absorbs dangerous ultraviolet radiation from the sun, protecting life and regulating climate. Consequently, meteorological agencies meticulously track "total ozone column," the amount of ozone in a vertical column of the atmosphere from the ground to its upper reaches.

The EUBREWNETEU network, which utilizes Brewer spectrophotometers to measure the total ozone column, was established in Europe in 2013. It has since evolved into a program contributing to the World Meteorological Organization's (WMO) Global Atmosphere Watch (GAW) program. However, the network's coverage has historically been concentrated in Europe, North America, and Oceania, leaving a relative scarcity of observation points in East Asia.

The addition of the Anmyeondo and Jeju Gosan stations marks a significant step in addressing this observational gap in Northeast Asia. The Meteorological Administration highlighted that their integration not only fills this void but also improves the spatial representativeness of the global network through the operation of equipment adhering to standardized international guidelines. These two sites are considered prime background observation locations, capable of monitoring atmospheric flow influenced by the Korean Peninsula and broader East Asian air currents.

Prior to this integration, the Jeju Gosan station had been observing the total ozone column using Brewer spectrophotometers since 2009, and Anmyeondo since 2013. Other Asian countries participating in the international ozone observation network include Malaysia, Singapore, the United Arab Emirates, and India, each with a single station.

The fact that Anmyeondo and Jeju Gosan have joined the observation network for the first time in Northeast Asia is significant in that it complements the observation gap in East Asia and enhances the spatial representativeness of the global observation network through equipment operation according to standardized guidelines.
