This review synthesizes the progress and achievements in developing Korea’s domestic greenhouse gas (GHG) concentration observation network, its data processing methods, and their applications. Since the establishment of monitoring stations in Tae-ahn Peninsula and Gosan in 1990, Korea has expanded its observation network, now ranking among the world’s densest ground-based GHG monitoring systems. Additionally, a three-dimensional monitoring framework incorporating aircraft, ships, and ground-based remote sensing has been implemented. Key findings indicate that background carbon dioxide concentrations over Korea are generally higher than the global average, with comparable annual increase rates but occasional discrepancies due to regional factors such as temperature and soil moisture. Methane concentrations in Korea are influenced by local and long-range emissions, as well as hydroxyl radical-induced decay, with substantial regional variability driven by agricultural and fossil fuel-related activities. Nitrous oxide levels slightly exceed the global average and exhibit notable seasonal variations. While chlorofluorocarbon (CFC) concentrations are declining worldwide, intermittent spikes in CFC-11 have been detected in Korea, prompting investigations into unexpected emissions. To analyze GHG concentration changes in Korea, tracer gas ratios and inverse modeling have been employed, enabling source attribution across diverse emission sectors, including agriculture, ocean, and fossil fuel combustion. Korea also plays an active role in global GHG monitoring by contributing to international observation networks and collaborative meas- urement campaigns. To further enhance the effectiveness of GHG monitoring in Korea, several key challenges must be addressed. First, ensuring standardized measurement protocols across monitoring sites is essential for maintaining data reliability. Second, future observation sites should be strategically selected to minimize local biases and improve repre- sentativeness. Third, enhancing trace gas and meteorological observations will be crucial for accurately identifying GHG sources and their contributions. Finally, strengthening collaboration between inventory and inversion modeling groups will improve the accuracy of national emission assessments.
