23 August 2022 – Niigata, Japan
The Network Center for the EANET organized the Seminar on Expanding Monitoring Systems using Low-Cost Sensor (LCS) online on 21 July 2022. It gathered representatives, experts, and practitioners of air quality monitoring from the EANET Participating Countries, and other participants from international organizations, academia, and monitoring-related service providers. 127 participants joined the Seminar.
.
Opening Session
The Seminar started with the Opening and Welcome Remarks by Dr. Shiro Hatakeyama, Director General of the Asia Center for Air Pollution Research (ACAP) in charge of the NC for the EANET, and by Dr. Mushtaq Memon, Regional Coordinator for Chemicals and Pollution Action Subprogramme, UNEP Regional Office for Asia and the Pacific. Remarks were followed by an Introductory Presentation by Mr. Taku Ohmura from the Overseas Environmental Cooperation Center, Japan (OECC) on the Overview of issues and opportunities of using LCS for air quality administrations and surveys.

Understanding Challenges and Opportunities of LCS
Key presentations by Dr. Supat Wangwongwatana, a Senior Instructor of the Faculty of Public Health, at Thammasat University, Thailand, and by Dr. Alison Simcox from the United States Environmental Protection Agency (US-EPA), delved into the limitations and opportunities of Low-cost sensor technology (LCS) for measuring air quality in the contexts of Thailand and of the United States.
Dr. Keiichi SATO, Head of the Atmospheric Research Department at ACAP, in charge of the NC for the EANET, then introduced the results of a survey on a Hybrid Air Quality Monitoring Network (HAQMN) and related technical studies in five EANET countries, namely Japan, Indonesia, Myanmar, Thailand, and Viet Nam.
His presentation was followed by discussions and presentations by Ms. Karma Yangzom, a Principal Environment Specialist from the Sustainable Development and Climate Change Department, at the Asian Development Bank (ADB), on ADB’s experience with LCS as part of the Technical Assistance (TA) 9608 on “Strengthening Knowledge and Actions for Air Quality Improvement”, and by Ms. Maria-Katharina Patdu’s presentation, an Associate Programme Officer, from the Asia Pacific Clean Air Partnership (APCAP), at UNEP Regional Office for Asia and the Pacific, on air quality data challenges and opportunities in developing Asia.
While the lack of precision of LCS and the variety of qualities and standards of sensors, may lead to data misinterpretation and presentation issues, keynote speakers and panelists mentioned that the cost-efficiency of LCS and the wide use of these air quality sensors by “citizen-scientists” educate the public and inspire behavioral changes. In addition, the effective utilization of regular monitoring data for the quality control of LCS, the importance of consistent city, regional, and country-level monitoring, and the continued cooperation with other networks and international organizations, were also key points presented to mitigate the limitations of LCS.
