Reflectivity of Venus' dayside disk during the 2020 observation campaign: outcomes and future perspectives
Yeon Joo Lee, Antonio García Muñoz, Atsushi Yamazaki +28
We performed a unique Venus observation campaign to measure the disk brightness of Venus over a broad range of wavelengths in August and September 2020. The primary goal of the cam…
Investigation of UV absorbers on Venus using the 283 and 365 nm phase curves obtained from Akatsuki
Y. J. Lee, A. García Muñoz, A. Yamazaki +3
The so-called unknown absorber in the clouds of Venus is an important absorber of solar energy, but its vertical distribution remains poorly quantified. We analyze the 283 and 365-…
Planetary-scale variations in winds and UV brightness at the Venusian cloud top: Periodicity and temporal evolution
Masataka Imai, Toru Kouyama, Yukihiro Takahashi +9
Planetary-scale waves at the Venusian cloud-top cause periodic variations in both winds and ultraviolet (UV) brightness. While the wave candidates are the 4-day Kelvin wave and 5-d…
Long-term variations of Venus' 365-nm albedo observed by Venus Express, Akatsuki, MESSENGER, and Hubble Space Telescope
Yeon Joo Lee, Kandis-Lea Jessup, Santiago Perez-Hoyos +16
An unknown absorber near the cloud top level of Venus generates a broad absorption feature from the ultraviolet (UV) to visible, peaking around 360 nm, and therefore plays a critic…
Principal Components of Short-term Variability in Venus' UV Albedo
Pushkar Kopparla, Yeon Joo Lee, Takeshi Imamura +1
We explore the dominant modes of variability in the observed albedo at the cloud tops of Venus using the Akatsuki UVI 283-nm and 365-nm observations, which are sensitive to SO2 and…
Return to Venus of the Japanese Venus Climate Orbiter AKATSUKI
Masato Nakamura, Yasuhiro Kawakatsu, Chikako Hirose +19
Japanese Venus Climate Orbiter/AKATSUKI was proposed in 2001 with strong support by international Venus science community and approved as an ISAS (The Institute of Space and Astron…
Equatorial jet in the lower to middle cloud layer of Venus revealed by Akatsuki
T. Horinouchi, S. Murakami, T. Satoh +15
The Venusian atmosphere is in a state of superrotation where prevailing westward winds move much faster than the planet's rotation. Venus is covered with thick clouds that extend f…
