A Model of UV-Blue Absorbance in Bulk Liquid of Venusian Cloud Aerosols Is Consistent with Efficient Organic Absorbers at High Concentrations

Jan Spacek, Yeon J. Lee, Paul B. Rimmer +1

At visible wavelengths, Venus appears serene and pale-yellow, but since the 1920s, observers have noted high-contrast features in the ultraviolet. These features track the about 4-…

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…

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…

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…

New cloud morphologies discovered on the Venus's night during Akatsuki

J. Peralta, A. Sánchez-Lavega, T. Horinouchi +8

During the years 2016 to 2018, the instruments Akatsuki/IR2 (JAXA) and IRTF/SpeX (NASA) acquired a large set of images at 1.74, 2.26 and 2.32 μm to study the nightside mid-to-lower…

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…
