Updated EANET Monitoring Site Information Accessible Online

29 July 2021 – Niigata, Japan

To provide useful inputs for decision-making at the local, national, and regional levels, the Acid Deposition Monitoring Network in East Asia (EANET) has been monitoring acid deposition in East Asia for over 20 years. Recently, an updated version of the Site Information page has been released, displaying detailed information on each monitoring site.


Monitoring Acid Deposition across East Asia

With a coverage expanded through Cambodia, China, Indonesia, Japan, Lao PDR, Malaysia, Mongolia, Myanmar, Republic of Korea, Russia, Thailand, Philippines, and Viet Nam, EANET has assisted over the years in the deployment of monitoring stations in very diverse urban, rural and remote locations.

These monitoring sites gather high-quality data related to the deposition of major acidifying species and related chemical substances such as SO42-, NO3, H+ in precipitation, SO2, NO2 ozone, and particulate matter (PM) in ambient air.

Dry and Wet Deposition Monitoring

Among the EANET’s major activities, acid deposition monitoring consists mainly in the review and revision or establishment of national monitoring plans, as well as the deployment of monitoring equipment, using common methodologies, to measure wet deposition, dry deposition, analyze the impacts of these depositions on soil and vegetation as well as on the inland aquatic environment.


Comprehensive Monitoring Site Information Available Online

Recently updated in June 2021, the Site Information webpage displays detailed information about the current 66 EANET monitoring sites, including, among others, each site’s address and location, characteristics, the monitoring period and items, and monitoring instrument name.

To find out more about the results and data on each site, visitors can also access the sites’ data reports on the Monitoring System Data Report page.
