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-day Rossby wave with zonal wavenumber 1, their temporal
evolutions a...

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 critical role in the solar energy absorption. We present
a quantitative s...

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 unknown UV absorber distributions respectively,
over the period De...
