Research Themes

RECCA promotes R&D to provide scientific knowledge obtained by the climate change projection for the regional (prefectures or cities) adaptation. For this purpose, RECCA implements 3 research themes as follows.


Though the 12 research topics chosen from the public are categorized into 3 themes, some of them cover more than a single theme.


Theme 1: Advanced Data Downscaling Methods

It is to develop multiple downscaling methods including dynamic and statistical ones, and new forward-thinking techniques. The goal is to take advantage of the global climate change projection model for a local-scale one and for impact assessments.

Theme 2: Data Assimilation Technology

It is to develop an assimilation technology for observation data to reduce uncertainty of the simulation model. The model supplies scientific knowledge to review regional climate change impact assessment and the adaptation.
