On June 02–06, 2025, the ISSI-BJ Workshop “Variability and Stability of the Venus' Atmosphere in Various Spatiotemporal Scales Inferred from Space Missions and Numerical Simulations” was held successfully. About 50 leading scientists from a range of institutes took part in the event, which was convened by Profs. Takehiko Satoh (Institute of Space and Astronautical Science/Japan Aerospace Exploration Agency, Japan), Hiroki Ando (Kyoto Sangyo University, Japan), Takeshi Imamura (The University of Tokyo, Japan), Jun Yang (Peking University, China), Yeon Joo Lee (Institute for Basic Science, Republic of Korea), Silvia Tellmann (University of Cologne, Germany), Itziar Garate Lopez (University of the Basque Country, Spain), and Kevin McGouldrick (University of Colorado Boulder, USA).

The Workshop’s main topics encompassed the variability and stability of the Venus’ atmosphere based on the analysis of data from space missions, as well as the numerical simulations. Since the duration of Akatsuki after the orbit insertion is becoming comparable to the one of the Venus Express', the data from both missions can be analyzed individually or by combination. Participants have identified points in common and differences in these two missions and interpret them in terms of mechanisms.

As scientific output, a new volume of the Space Science Series of ISSI will be published covering the content of this Workshop, for distribution to both the science community and space science institutions.
