©2017. The Authors. We present the first comparison of Jupiter's auroral morphology with an extended, continuous, and complete set of near-Jupiter interplanetary data, revealing the response of Jupiter's auroras to the interplanetary conditions. W...

Image velocimetry for clouds with relaxation labeling based on deformation consistency

Takeshi Horinouchi Shin-ya Murakami Toru Kouyama Kazunori Ogohara Atsushi Yamazaki Manabu Yamada Shigeto Watanabe

MEASUREMENT SCIENCE AND TECHNOLOGY 28(8) 2017年8月 [査読有り]

Correlation-based cloud tracking has been extensively used to measure atmospheric winds, but still difficulty remains. In this study, aiming at developing a cloud tracking system for Akatsuki, an artificial satellite orbiting Venus, a formulation ...

Dawn-dusk difference of periodic oxygen EUV dayglow variations at Venus observed by Hisaki

© 2016 Elsevier Inc. We report a dawn-dusk difference of periodic variations of oxygen EUV dayglow (OII 83.4 nm, OI 130.4 nm and OI 135.6 nm) in the upper atmosphere of Venus observed by the Hisaki spacecraft in 2015. Observations show that the pe...

Scattering Properties of the Venusian Clouds Observed by the UV Imager on board Akatsuki

Y. J. Lee A. Yamazaki T. Imamura M. Yamada S. Watanabe T. M. Sato K. Ogohara G. L. Hashimoto S. Murakami

ASTRONOMICAL JOURNAL 154(1) 2017年7月 [査読有り]

We analyze the albedo of Venus obtained from the UV Imager on board Akatsuki. A relative global mean albedo over phase angle is used in this study, and we confirm the glory feature at 283 and 365. nm in the data acquired in 2016 May. We successful...

Global distribution of the He⁺ column density observed by Extreme Ultra Violet Imager on the International Space Station

Yuta Hozumi Akinori Saito Ichiro Yoshikawa Atsushi Yamazaki Go Murakami Kazuo Yoshioka Chia Hung Chen

Journal of Geophysical Research: Space Physics 122(7) 7670-7682 2017年7月

The global distribution of He+ in the topside ionosphere was investigated using data of the He+ resonant scattering emission at 30.4 nm obtained by the Extreme Ultra Violet Imager (EUVI) onboard the International Space Station. The optical observa...
