Workshop on atmospheric models of Venus and others


This workshop has been POSTPONED due to the new coronavirus.

An updated schedule will be announced later.


The scope of the workshop is to gather scientists working on modeling and observation of Venus atmosphere and to discuss recent results from Akatsuki ovserbations and simulations with Venus atmospheric GCMs in various groups. Recent modeling results of other planetary atmospheres (e.g., Mars and Saturn) will be also discussed.


March 20th - 21st, 2020
