Overview of the Preliminary Draft Data Report 2020 and Evaluation of the Results of the Inter-laboratory Comparison (ILC) Projects 2020

The NC presented the Preliminary Draft Data Report 2021. This report focuses on wet deposition, dry deposition (air concentration), soil and vegetation, inland aquatic environment, and catchment-scale monitoring. It includes a summary of the monitoring data in 2021 and related information submitted by the Participating Countries.

The NC also introduced the preliminary draft Report on the Inter-laboratory Comparison Projects in 2021 for wet deposition, dry deposition (filter pack method), soil, and inland aquatic environment.


Consideration of the National Monitoring Plans (NMPs), Current Monitoring Activities for the EANET and Overall Air Concentration Monitoring Status of the Participating Countries

In line with previous STM meetings’ process, representatives of the Participating Countries presented their National Monitoring Plans (NMPs) and current EANET activities, including monitoring capacities, technical challenges, and future plans, while focusing on the general improvement of the activities of the EANET.

Other important matters were also discussed, including the progress on the Revision of the Technical Manuals for Dry Deposition Flux Estimation and Air Concentration Monitoring.

Dr. Meng Fan, Deputy Director General, ACAP, delivered the Closing Remarks. He expressed his great appreciation for the improvement of the data quality due to the efforts of the Participating Countries and hoped that the EANET monitoring, research and capacity-building activities would continue to be strengthened through the expansion of the scope of the EANET.
