National Monitoring Plans and Future Directions
The meeting also focused on presentations related to National Monitoring Plans and current monitoring activities of the Participating Countries. Each country shared updates on air concentration monitoring and technical challenges, including equipment issues and the need for continued maintenance support.
Discussions covered future developments in EANET’s monitoring and analysis activities, with an emphasis on expanding the monitoring network and integrating cost-effective, hybrid air quality monitoring systems. Participants also addressed the potential for capacity-building efforts related to volatile organic compounds (VOCs) and nitrogen management.

Key Trends and Findings
The Data Report 2023 revealed decreasing levels of sulfate (SO4²⁻) and nitrate (NO3⁻) across many monitoring sites, signaling a positive recovery from acid deposition in the region. However, ongoing monitoring is essential to confirm these trends. The meeting emphasized the importance of data sharing, timely submissions, and continuous QA/QC of data.
The STM meeting concluded with a summary of National Monitoring Plans by the Network Center, highlighting the progress made and identifying areas for future development. Dr. Meng Fan, Deputy Director General of the Asia Center for Air Pollution Research (ACAP), praised the Participating Countries for their continuous efforts and contributions to improving the EANET data quality. He called for ongoing collaboration to strengthen EANET’s role in combating acid deposition and air pollution in East Asia.
