Seasonal Variation of Wet Deposition of Black Carbon at Ny-Ålesund, Svalbard
Mori, Tatsuhiro; Kondo, Yutaka; Ohata, Sho; Goto-Azuma, Kumiko; Fukuda, Kaori; Ogawa-Tsukagawa, Yoshimi; Moteki, Nobuhiro; Yoshida, Atsushi; Koike, Makoto; Sinha, P. R.; Oshima, Naga; Matsui, Hitoshi; Tobo, Yutaka; Yabuki, Masanori; Aas, Wenche (Peer reviewed; Journal article, 2021)Black carbon (BC) aerosol deposited in and onto Arctic snow increases the snow's absorption of solar radiation and accelerates snowmelt. Concentrations of BC in the Arctic atmosphere and snow are controlled by wet deposition; ... -
Surface warming in Svalbard may have led to increases in highly active ice-nucleating particles
Tobo, Yutaka; Adachi, Kouji; Kawai, Kei; Matsui, Hitoshi; Ohata, Sho; Oshima, Naga; Kondo, Yutaka; Hermansen, Ove; Uchida, Masaki; Inoue, Jun; Koike, Makoto (Peer reviewed; Journal article, 2024)The roles of Arctic aerosols as ice-nucleating particles remain poorly understood, even though their effects on cloud microphysics are crucial for assessing the climate sensitivity of Arctic mixed-phase clouds and predicting ...
