The 2nd International Symposium on the Whole Atmosphere (ISWA2)

7-9 June 2027
The University of Tokyo, Tokyo, Japan & Online

Recent advances in observational techniques and the expansion of observational networks have enabled the simultaneous capture of atmospheric phenomena across a broad range of temporal and spatial scales. In parallel, global numerical models — including coupled climate models, chemistry-climate models, and models that incorporate data assimilation — are being extended to higher altitudes with enhanced horizontal and vertical resolutions. These developments now make it possible to examine phenomena in the real atmosphere and their interactions across multiple scales, including inter- and intrahemispheric couplings.

The resulting increase in the volume and complexity of observational and model data highlights the growing importance of data analysis methods, prompting a shift toward more data-centric science. At the same time, new theoretical frameworks have been developed to treat diverse atmospheric phenomena seamlessly and in three dimensions, with an emphasis on inductively derived structures.

The International Symposium on the Whole Atmosphere (ISWA) was held at the University of Tokyo in September 2016, showcasting state-of-the-art research at the time on the whole atmosphere, with particular focus on the dynamics of the middle and upper atmosphere. Following the success of the first symposium and in light of the significant developments in the field over the past decade, we are pleased to announce the second symposium, ISWA2, to be held from 7 to 9 June 2027 at the University of Tokyo.

In 2027, the PANSY radar at Syowa Station in Antarctica will complete its originally-planned 12 years of operation with its full system, providing a unique opportunity to analyze long-term data from the polar atmosphere. Marking this milestone, we hope to make ISWA2 an opportunity to review recent research outcomes and to discuss future directions for research on the whole atmosphere.
