Autor: Kana Nagashima, Hajime Kawakami, Koji Sugie, Tetsuichi Fujiki, Jun Nishioka, Yoko Iwamoto, Toshihiko Takemura, Takuma Miyakawa, Fumikazu Taketani, Maki Noguchi Aita

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-10 (2023)

Abstract Iron availability limits marine ecosystem activities in large areas of the ocean. However, the sources and seasonal supply of iron, critically important for controlling surface ocean biogeochemistry and carbon cycling, are poorly understood.

Aerosol–Cloud Interaction at the Summit of Mt. Fuji, Japan: Factors Influencing Cloud Droplet Number Concentrations

Autor: Yoko Iwamoto, Ayami Watanabe, Ryota Kataoka, Mitsuo Uematsu, Kazuhiko Miura

Publikováno v: Applied Sciences, Vol 11, Iss 18, p 8439 (2021)

To investigate interactions between aerosols and clouds, the size and number concentrations of the cloud condensation nuclei (CCN) and the cloud droplets (CDs) were measured at the summit of Mt. Fuji (altitude 3776 m), Japan. The CCN number concentra

Detection of Aerosol Particles from Siberian Biomass Burning over the Western North Pacific

Autor: Momoka Yoshizue, Fumikazu Taketani, Kouji Adachi, Yoko Iwamoto, Yasunori Tohjima, Tatsuhiro Mori, Kazuhiko Miura

Publikováno v: Atmosphere, Vol 11, Iss 11, p 1175 (2020)

Carbonaceous aerosol particles emitted from biomass burning (BB) have a large impact on the global climate. In particular, tarball particles (TBs), which are spherical organic aerosol particles, account for a large proportion of aerosol particles fro

Marine nitrogen fixation as a possible source of atmospheric water-soluble organic nitrogen aerosols in the subtropical North Pacific

Autor: Tsukasa Dobashi, Yuzo Miyazaki, Eri Tachibana, Kazutaka Takahashi, Sachiko Horii, Fuminori Hashihama, Saori Yasui-Tamura, Yoko Iwamoto, Shu-Kuan Wong, Koji Hamasaki

Publikováno v: Biogeosciences. 20(2):439-449

Water-soluble organic nitrogen (WSON) in marine atmospheric aerosols affect the water solubility, acidity, and light-absorbing properties of aerosol particles, which are important parameters in assessing both the climate impact and the biogeochemical

Marine aerosol feedback on biogeochemical cycles and the climate in the Anthropocene: lessons learned from the Pacific Ocean

Autor: Akinori Ito, Yuzo Miyazaki, Fumikazu Taketani, Yoko Iwamoto, Yugo Kanaya

Publikováno v: Environmental Science: Atmospheres. 3:782-798

Marine aerosol feedback on biogeochemical cycles and the climate remains highly uncertain due to the complex interplay. This review highlights recent advances in our understanding of organic aerosols, nitrogen, and iron as well as cloud properties ov

Morphological features and water solubility of iron in aged fine aerosol particles over the Indian Ocean

Autor: Sayako Ueda, Yoko Iwamoto, Fumikazu Taketani, Mingxu Liu, Hitoshi Matsui

Atmospheric transport of iron (Fe) in fine anthropogenic aerosol particles is an important route of soluble Fe supply to remote oceans from continental areas. To investigate Fe properties of aerosol particles over remote oceans, we analyzed atmospher

Roles of marine biota in the formation of atmospheric bioaerosols, cloud condensation nuclei, and ice-nucleating particles over the North Pacific Ocean, Bering Sea, and Arctic Ocean

Autor: Kaori Kawana, Fumikazu Taketani, Kazuhiko Matsumoto, Takuma Miyakawa, Yutaka Tobo, Yoko Iwamoto, Akinori Ito, Yugo Kanaya

We investigated the association of marine biological indicators (polysaccharides and protein-like gel particles, Chl-a) with the formation of fluorescent aerosol particles, cloud condensation nuclei (CCN), and ice-nucleating particles (INPs) over the
