    There has been a societal controversy in Japan for many years regarding the estimation of the area of the "Black Rain" that occurred soon after the atomic bombings of Hiroshima and Nagasaki in 1945. Estimates of the area have been constructed primarily on the basis of testimonies and experiences, but there is a scarcity of material evidence from which the area can be estimated. The "Black Rain" consists of a complex mixture of radioactive materials from the A-bomb, dust generated by the shock wave, and the smoke of the city fire, etc. Typically, the precipitation colored black, but some testimonies suggest that it was muddy rain, colorless, etc. We define the "Black Rain" here as a comprehensive term for fallout in the vicinity (close-in fallout), including dry deposition processes. Since January 2021, we have been conducting research focusing on the following two subjects in order to contribute to resolve the issue. In this special issue, we introduce (1) the reproduction of the "Black Rain" by using meteorological simulation models including explosion and urban fires, and (2) efforts to clarify the geographical distribution and characteristics of fallout by analyzing it, which will contribute to better understand of the affected area caused not directly by ionizing and heat radiations from nuclear explosion but by the "Black Rain". The presentation will also attempt to organize relating information on the "Black Rain".

    This special issue highlights the latest scientific findings in the issues and key words of “Earth, Isotopes and Organics.” The Earth harbors the diverse elements that make up organic molecules with Carbon (C), Hydrogen (H), Nitrogen (N), Oxygen (O), Sulfur (S), and Phosphorus (P). Major inorganic elements represented by magnesium (Mg) and iron (Fe) also have important roles for biosphere. Those diverse elements have also stable and radioactive isotopes in their natural compositions. Standardization through international standard references is underway to develop highly accurate and precise analytical methodology. These highly precise isotope measurements are robust chemical tools in deciphering the interaction between biotic and abiotic factors. Therefore, this special issue can be defined as the understanding of the life science and chemistry on the Earth (e.g., biosphere, hydrosphere, and geosphere) through the representation of essential elements associated with inorganic and organic molecules in nature. In this special issues, further perspectives for state-of-the-art developments in compound-specific isotope analysis will be overviewed for next decadal progresses.

    The western North Pacific is recognized as a large sink region for CO2, involving complex interactions across multiple spheres in the cycling process. Recent rapid climate changes have perturbed the biogeochemical and physical processes in the atmosphere and ocean of this region. To enhance our understanding of these processes in this region, integrated and cross-cutting studies are essential, encompassing the Atmosphere, Hydrosphere, Biosphere, and Humanosphere across various temporal and spatial scales.

    In this special issue SPEPS, we invite authors to contribute their latest studies and/or reviews focusing on Atmosphere, Ocean, and Atmosphere-Ocean Interaction in the western North Pacific region. We particularly welcome multidisciplinary studies that couple chemical, biological, and/or physical topics related to the atmosphere and ocean, obtained from ship-based observation, numerical model calculations, satellite data analysis, and laboratory experiments. Discussions centered on ground-based observation surrounding the western North Pacific are also welcomed.

    The Asian monsoon is an inter-hemispheric atmospheric system driven by thermal contrast between land and ocean, involving regions where more than half of the global population lives. Concerns grow that climate change will cause extreme events linked to the Asian monsoon, such as extraordinarily heavy rainfall, flooding, drought, or heat waves. Deciphering relationships between the past and present Asian monsoon and climate variability will provide valuable insights into the mechanisms behind these extreme events and Earth's climate system.

    Variation in the Asian monsoon is both influenced by the surrounding environment and itself influences the marine environment of the Indo-Pacific and marginal seas. For instance, ocean temperatures around these regions have played important roles on Asian monsoon variability by changing the land-ocean thermal contrast. On the other hand, variability in the Asian monsoon influences the surrounding regions through water vapor circulation, riverine discharge, physical and chemical weathering, transportation of detritus and nutrients, dust emission and transport, and other environmental impacts. Therefore, paleoenvironmental reconstructions of this region are necessary to understand the many links between the Asian monsoon and terrestrial and oceanic systems.

    This special issue focuses on past change of Asian monsoon and oceanographic conditions in the Indo-Pacific region, and their relationship with the global climate change over various timescales. It addresses paleoenvironmental reconstruction of terrestrial and marine regions and interplay between them with emphasis on the Asian monsoon, the Japan Sea, and the western North Pacific during the late Cenozoic.

    Global warming accelerates Arctic sea ice retreat, which feeds back to significant changes in atmospheric-terrestrial water cycle in the Arctic and subarctic regions. These large-scale environmental changes alter the condition of surface water and vegetation, affecting spatiotemporal variations in greenhouse gases budget. To better understand water–carbon cycles in these regions, integrated studies on atmospheric–terrestrial water–carbon cycles are required.

    In this special issue SPEPS, we thus invite authors to contribute latest researches or reviews focusing on atmospheric–terrestrial water and carbon cycles in the Arctic and subarctic regions. Studies aiming to reveal spatiotemporal variations in the atmospheric moisture transport, moisture flux convergence, precipitation, vegetation, permafrost degradation, greenhouse gas fluxes, and the Arctic river discharges and their impacts on peripheral seas are highly welcomed, including the future projections. Additionally, interdisciplinary and transdisciplinary researches in cross-cutting with sociological studies are also welcomed.
