A Recharge Oscillator Model for Interannual Variability in Venus' Clouds
Pushkar Kopparla, Ashwin Seshadri, Takeshi Imamura +1
Sulfur dioxide is a radiatively and chemically important trace gas in the atmosphere of Venus and its abundance at the cloud-tops has been observed to vary on interannual to decada…
A Long-lived Sharp Disruption on the Lower Clouds of Venus
J. Peralta, T. Navarro, C. W. Vun +19
Planetary-scale waves are thought to play a role in powering the yet-unexplained atmospheric superrotation of Venus. Puzzlingly, while Kelvin, Rossby and stationary waves manifest…
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…
Global structure of thermal tides in the upper cloud layer of Venus revealed by LIR onboard Akatsuki
T. Kouyama, M. Taguchi, T. Fukuhara +11
Longwave Infrared Camera (LIR) onboard Akatsuki first revealed the global structure of the thermal tides in the upper cloud layer of Venus. The data were acquired over three Venusi…
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…
