27 August 2020 – Niigata, Japan

The Twenty-First Senior Technical Managers’ Meeting (STM21) on the Acid Deposition Monitoring Network in East Asia (EANET) was held online on 7 August 2020. The Meeting was organized by the Network Center (NC) for the EANET in collaboration with the Secretariat for the EANET. About 40 senior technical officials involved in the EANET monitoring activities from Cambodia, China, Indonesia, Japan, Lao PDR, Malaysia, Mongolia, Myanmar, Philippines, Republic of Korea, Russia, Thailand, and Viet Nam participated in the meeting.

Acid Deposition Monitoring Activities in 2019

The objectives of this annual meeting were to exchange information on the current status of the EANET monitoring activities, including the consideration of the draft Data Report 2019 and the draft Inter-laboratory Comparison Project Report 2019, as well as to discuss the EANET’s National Monitoring Plans for 2020.

During the meeting, the NC presented the preliminary draft Data Report 2019 which contains wet deposition, dry deposition (air concentration), soil and vegetation, inland aquatic environment, and catchment-scale monitoring data, as well as a summary of the monitoring data of 2019 and related information submitted by the 13 EANET Participating Countries in 2019.

The representatives of the EANET Participating Countries, later on, presented their National Monitoring Plans and current EANET activities, including monitoring capacities, technical limitations, future plans, etc. Throughout the meeting, the senior technical officials discussed implementation challenges and shared their experiences and knowledge to foster solutions in favor of future innovation.

Expanded Monitoring Sites in 2020

In 2020, the number of the EANET monitoring sites has significantly increased, with a total number of 60 wet deposition monitoring sites, 47 dry deposition monitoring sites, 21 soil and vegetation monitoring sites, 19 inland aquatic environment monitoring sites, and 2 catchment-scale monitoring sites, located in 13 countries of Asia.

Most recently, China started monitoring wet and dry deposition in two newly registered EANET monitoring sites: in Wuzhishan, Hainan Province, and Lijiang, Yunnan Province. Indonesia also introduced two new EANET monitoring sites: in Jembrana, in the province of Bali, and Lombok Barat, in West Nusa Tenggara Province.
