EANET data continued to play an important role in international scientific research during 2024–2025, with over 135 peer-reviewed papers using the network’s long-term monitoring datasets to examine atmospheric chemistry, ecosystem impacts, and regional air-pollution trends. The number of research highlights the important scientific value of harmonized regional monitoring systems in addressing regional air-pollution challenges.

Advancing Understanding of Atmospheric Deposition and Air Pollution

A large share of recent publications used EANET observations to investigate wet and dry deposition of nitrogen, sulfur, and other atmospheric pollutants across East and Southeast Asia. Studies examined long-term deposition trends, spatial variability of precipitation chemistry, and seasonal patterns in pollutant concentrations (e.g., Temporal and seasonal variations in high-concentration precipitation samples at EANET sites in Japan: 20 years of wet-deposition data, 2025; Spatiotemporal distribution in chemical composition of wet atmospheric deposition in Bandung, Indonesia, 2024), contributing to improved understanding of how emission changes influence regional environmental conditions.

EANET datasets were also widely applied in atmospheric modelling research. Scientists incorporated the measurements to evaluate chemistry-climate models, refine emission inventories, and improve simulations of aerosol formation, transport, and deposition processes (e.g., Evaluation of atmospheric sulfur dioxide simulated with the EMAC chemistry-climate model using satellite and ground-based observations, 2025). Such work strengthens the reliability of regional and global air-quality projections used in policy and climate assessments.

Regional Data Supporting Global Science and linking Air Pollution, Ecosystems, and Climate

Beyond atmospheric science, researchers increasingly used EANET data to explore environmental impacts of deposition on ecosystems. Recent studies analysed nitrogen inputs to lakes and forested watersheds, relationships between acid deposition and vegetation changes, and long-term variations in stream and precipitation chemistry (e.g., Wet and dry deposition of atmospheric nitrogen to Lake Erhai Basin: Composition, spatiotemporal patterns and implications, 2025). These findings help clarify how atmospheric pollution interacts with climate variability and ecosystem health across the region.

In addition, several global-scale investigations incorporated EANET measurements to evaluate worldwide nitrogen-deposition trends and to assess future scenarios under changing socio-economic and climate conditions (e.g., Changing patterns of global nitrogen deposition driven by socio-economic development, 2025), demonstrating the EANET’s contribution to global environmental assessments.

Strengthening Evidence-Based Regional Cooperation

The increasing number of publications using EANET data reflects both the growing accessibility of standardized monitoring datasets and the importance of long-term observations for regional cooperation. By providing comparable measurements across multiple Participating Countries, EANET enables cross-country analyses that support scientific collaboration, policy evaluation, and improved understanding of regional air pollution.
