Autor: K. Kino, A. Cauquoin, A. Okazaki, T. Oki, K. Yoshimura

Publikováno v: Geophysical Research Letters, Vol 51, Iss 8, Pp n/a-n/a (2024)

Abstract Stable water isotopes in inland Antarctic ice cores are powerful paleoclimate proxies; however, their relationship with dynamical atmospheric circulations remains controversial. Using a water isotope climate model (MIROC5‐iso), we assessed

Nanostructure and Magnetic Field Ordering in Aqueous Fe3O4 Ferrofluids: A Small-Angle Neutron Scattering Study

Autor: A. Taufiq, S Sunaryono, N. Hidayat, E.G.R Putra, A. Okazawa, I. Watanabe, N. Kojima, S. Pratapa, D. Darminto

Publikováno v: Atom Indonesia, Vol 45, Iss 3, Pp 165-172 (2019)

Despite the importance of reducing production costs, investigating the hierarchical nanostructure and magnetic field ordering of Fe3O4 ferrofluids is also important to improve its application performance. Therefore, we proposed an inexpensive synthes

Autor: A. Okazaki, T. Honda, S. Kotsuki, M. Yamaji, T. Kubota, R. Oki, T. Iguchi, T. Miyoshi

Publikováno v: Atmospheric Measurement Techniques, Vol 12, Pp 3985-3996 (2019)

Spaceborne precipitation radars, such as the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) Core Observatory, have been important platforms to provide a direct measurement of three-dimensional precipitation

Development and evaluation of a system of proxy data assimilation for paleoclimate reconstruction

Autor: A. Okazaki, K. Yoshimura

Publikováno v: Climate of the Past, Vol 13, Iss 4, Pp 379-393 (2017)

Data assimilation (DA) has been successfully applied in the field of paleoclimatology to reconstruct past climate. However, data reconstructed from proxies have been assimilated, as opposed to the actual proxy values. This prevented full utilization

Interannual variability of isotopic composition in water vapor over western Africa and its relationship to ENSO

Autor: A. Okazaki, Y. Satoh, G. Tremoy, F. Vimeux, R. Scheepmaker, K. Yoshimura

Publikováno v: Atmospheric Chemistry and Physics, Vol 15, Iss 6, Pp 3193-3204 (2015)

This study was performed to examine the relationship between isotopic composition in near-surface vapor (δ18Ov) over western Africa during the monsoon season and El Niño–Southern Oscillation (ENSO) activity using the Isotope-incorporated Global S
