Dr. Tsuyoshi Ohizumi and Dr. Hiroyuki Sase received the Academic Award of the Japan Society for Atmospheric Environment (JSAE) at the 62nd and 63rd Annual Meetings of the JSAE in 2021 and 2022 respectively. Dr. Ohizumi serves as the Head of Data Management Department of the Asia Center for Air Pollution Research (ACAP), Network Center (NC) for the EANET, and Dr. Sase as the Head of Ecological Impact Research Department of the ACAP, NC for the EANET. Prior to these two awards, Dr. Junichi Kurokawa, Principal Researcher of the Data Management Department of ACAP, received the Creative Work Award for Young Scientists of JSAE under the award-winning title of “A study on emission inventory in Asia” in 2013.

Award-Winning Studies on Effects of Acid Deposition in Japan and in the East Asian Region
Dr. Tsuyoshi Ohizumi

Dr. Ohizumi received the Academic Award of the Japan Society for Atmospheric Environment at the 62nd Annual Meeting of the JSAE in 2021 for his studies of the transboundary transportation of air pollutants by observation of sulfur isotopic composition.

Through his work, seasonal differences and major routes of inter-regional transport of pollutants were clarified by streamline analysis of air mass that causes acid precipitation and observation of fluoride and other substances in atmospheric deposition. In addition, the long-term interregional transport of sulfur oxides, the cause of acid rain, was also quantitatively evaluated by observing stable isotope ratios of sulfur in atmospheric deposition at sites along the Sea of Japan.

In 2022, Dr. Sase received the Academic Award of the Japan Society for Atmospheric Environment at the 63rd Annual Meeting of the JSAE for his various studies on the atmospheric environment and its effects on forest ecosystems in Japan and other East Asian countries.

Through EANET activities and joint research with the Participating Countries of the EANET, his work has significantly contributed to understanding the effects of acid deposition and air pollution on forest ecosystems in the East Asian region through field observation and data assessments over many years.

The Japan Society for Atmospheric Environment

The Japan Society for Atmospheric Environment (JSAE) is an interdisciplinary organization that brings together experts in a wide range of fields with the aim of contributing to atmospheric environment conservation.

JSAE has four awards for achievements in the field of the atmospheric environment: the Academic Award, the Meritorious Contribution Award, the Technical Development Award, and the Best Paper Award.

Dr. Ohizumi and Dr. Sase received the Academic Award, the highest honor for researchers. The purpose of the Academic Award of JSAE is to honor members for their academic achievements in the field of atmospheric environment research, their social contributions to the promotion of atmospheric quality administration, and for their contribution to the development of JSAE.

New Face of EANET Research Portal

Posted on by Aurélia Lemoine

29 September 2021 – Niigata, Japan

EANET researchers have been working collaboratively for 20 years to study mechanisms of acid deposition and its effects on ecosystems, resulting in various scientific publications. These aim at creating a common understanding of the state of acid deposition problems in East Asia, and to provide useful inputs for decision-making at the local, national, and regional levels. Recently, an updated version of the EANET Research Portal has been released, displaying detailed information on EANET research activities.

.

20 Years of Research Activities

Why is research a central component of EANET’s activities? Since the early 2000s, collaboration on data monitoring and research has significantly improved knowledge on environmental urgencies in the region. With monitoring sites deployed in 13 countries in East Asia, scientists and researchers have access to unique data on acid deposition and air pollution.

In the decision-making process, policymakers need scientific-based evidence to guide their choices. They often use scientific results to evaluate the benefits of environmental policies and to shape government programs.

Over the years, EANET’s ability to bring together diverse players such as scientists, researchers, students, young professionals, and policymakers has made it a unique knowledge-sharing platform.

.

Sharing Scientific Outputs and Fostering Collaboration Globally

The EANET Research Portal was created to promote research activities developed in the EANET community and to enhance the use of the EANET data by the scientific community globally.

The main objectives of this page are to introduce research activities conducted by the EANET community, share scientific outputs from the EANET research activities, demonstrate the importance of the EANET data for scientific research activities, and provide opportunities for joint research activities with the EANET community.

More specifically, users can access scientific articles produced by the EANET Community, Reports of the EANET Fellowships, EANET Science Bulletins, and a database of research articles using and/or mentioning EANET data.

.

How Can Researchers Contribute to the Portal?

To expand the reach of this portal, Participating Countries are invited to share this page with their scientific peers at a national level, to link this page to their websites, and help improve its content by informing the EANET Network Center on any important paper using EANET data that might be missing from the database.

Scientific & Technological Research Papers from Participating Countries – Airborne Ammonia Concentrations in the Baikal Region

1 April 2021 – Niigata, Japan

Scientific and Technological Research Papers from Participating Countries are research articles written by scientists from the EANET Participating Countries, in collaboration with the EANET Network Center, in Niigata, Japan. They are published in the EANET Science Bulletin and have required the use of EANET data.

Alisa Trifonova-Yakovleva and Sergey Gromov, from Russia, estimated airborne concentrations of ammonia (NH3) in the Baikal region by using measurements conducted at two EANET monitoring sites and compared with satellite data (Infrared Atmospheric Sounding Interferometer (IASI)).

.

Sources and Impacts of Ammonia

Ammonia (NH3) is an important air pollutant that may eventually fall back to earth by means of wet and dry acid deposition. It is emitted both naturally and from anthropogenic sources such as animal husbandry, the use of nitrogen fertilizers, and biomass burning.

Atmospheric deposition containing NH3, aside from acidification impacts through the oxidizing to nitric acids in rain waters or on wet surfaces, cause also other negative effects on ecosystems, such as eutrophication and loss of biodiversity. In addition, when NH3 reacts with other atmospheric constituents, it forms particulate matter (e.g. PM2.5) triggering harmful impacts on human health.

Airborne Ammonia Concentrations in the Baikal Region

For this research study, Alisa Trifonova-Yakovleva and Sergey Gromov used satellite data for better coverage and understanding of the air pollution at a wider regional level and ground-based measurements (filterpack method) at the Russian Litstvyanka and Mondy EANET stations from 2015 to 2017.

The goal of this study was to understand the constant levels of NH3 concentrations or their higher values of episodic nature in different locations within the Baikal Region, season-to-season.

More precise estimations of the regional airborne NH3 concentrations are indeed necessary to enhance the understanding of the scales and extension of detrimental impacts of air pollution and acid deposition on the environment and on human health.

This study was carried out in the framework of the Research Project AAAA-A20-120013190049-4 “Development of methods and technologies for monitoring of environmental pollution under the influence of transboundary pollutants transport (UNECE: EMEP, ICP IM) and acid deposition in East Asia (EANET)”.

Processing of satellite measurement data was performed as part of the research theme under the Plan of Basic Scientific Research of the State Academies of Sciences No. 0148-2019-0009, AAAA-A19-119022190173-2 “Climate changes and their consequences for the environment and the life of the population in Russia”.
