We first observed the exchange flux of ammonia over a tropical forest in Thailand. Measurements were taken during two periods in the dry season with different environmental conditions. This data improves our understanding of how ammonia behaves in forests under tropical climates and helps refine models that estimate nitrogen deposition and assess its impact across East Asia.

The JapanFlux2024 dataset, created through collaboration across Japan and East Asia, includes eddy covariance data from 83 sites spanning 683 site-years (1990–2023). This comprehensive dataset offers valuable insights into energy, water, and CO2 fluxes, supporting research on land–atmosphere interactions and process models; fosters global collaboration; and advances research in environmental science and regional climate dynamics.

Short summary
This study examined biogenic volatile organic compounds in a suburban Tokyo forest using tower and supplemental drone measurements. Isoprene showed clear seasonal and vertical variations, while drone observations indicated spatial heterogeneity. Comparison with the Model of Emissions of Gases and Aerosols from Nature showed that site-specific parameter refinement is needed.
