Session 1: Validation (Observation data) Chair: Kei Yoshimura (AORI) / Rapporteur: Rajan Bhattarai (Department of Irrigation, Government of Nepal)
Though we have a super-high resolution RCM, we could not drive it with a high accuracy without validating the model results with the observation data with the same resolution. And also, we introduce many kinds of the observation data which would be candidates for the validation data. For this purpose, we introduce isotope data, remote sensing data as TRMM, radar data, which have over 10 years long data. The potential of using any new kind of observation data would be discussed.

Session 2: Mechanism appeared in climate change condition (Projection across the scales) Chair: Hiroaki Kawase (MRI) / Rapporteur: Kenshi Hibino (University of Tsukuba)
The accuracy of the downscaling data is guaranteed by its research on the climatic mechanism. For example, Asian winter and summer monsoons mainly control the regional climate in East Asia, which are influenced by global-scale climate changes including SST changes. On the other hand, future changes in local-scale precipitation, temperature, snowfall, and snow depth results from the modulated Asian monsoon via the complex orographic effects, the land surface effects including urbanization, and so on. We need to clarify the relations between the global-, regional-, and local-scale phenomena for the interpretation of regional climate changes. To clarify the mechanism on changes of extreme phenomena, for example tropical depressions are also good examples of the topic.

Session 3: Sub-model processes appeared explicitly in very-high resolution models Chair: Mizuo Kajino (MRI) / Rapporteur: Masaya Kato (HyARC)
As the grid size of the RCM become finer than 5km, many physical processes should be handled more carefully than a coarser resolution model. For example, cloud micro-physics has become apparent, large eddy become apparent in the ABL model, many sub-grid scale structure of the land surface scheme has become apparent. Also, we have to consider the indirect effect of aerosols. The influence of considering these items should be discussed.

Session 4: Application (Agenda building with the end-users) Chair: Yingjiu Bai (Keio University) / Rapporteur: Faye Cruz (Manila Observatory)
As the horizontal resolution of DS becomes finer, the applicability of the DS data becomes large. Also, in the framework of Future Earth (http://www.iscu.org/future-earth), it is encouraged to co-work with the social scientists, sociologists, and end users of climate change information, to build agenda of how to use the climate change data. Here we focus on the potential and limitation of such application studies.
