Japanese Venus climate orbiter named Akatsuki was launched in 2010. It orbited the Sun for five years and was inserted into the Venus orbit in December 2015. Akatsuki has five cameras and one ultra-stable oscillator: the cameras and the oscillator enable us to investigate horizontal and vertical structures of the Venus atmosphere, respectively. In addition to Akatsuki, we have also investigated the Venus atmosphere by the ground-based telescopes. In this presentation, we are going to show the observational results obtained by the Akatsuki and the ground-based telescope measurements and discuss the present situation of the Venus atmospheric science.

Short bio: Dr. Hiroki Ando was born in Chiba, Japan, in 1986. He received BS in mathematics from Waseda University, Japan, in 2008. After that, he received MS and PhD in earth and planetary science from The University of Tokyo, Japan, in 2010 and 2013, respectively. In 2013-2016, he belonged to Japan Aerospace Exploration Agency (JAXA) as a project researcher of Akatsuki. In 2016, he moved to Kyoto Sangyo University, and now he is an associated professor of Faculty of Science in it. He is also a core member of the Akatsuki radio occultation team. His work focuses specifically on the Venusian and Martian atmospheric structures by radio occultation technique and numerical modeling.
