| 研究開始時の研究の概要 |
The Global-to-Regional Urban Climate Change Assessment and Modeling (GRUCCAM) project advances a subfield called "Global Urban Climatology" (GUC). GUC aims to acquire a universal understanding of city-climate interactions in multiple scales. Global-covering urban parameter datasets from publicly available sources (e.g. satellite imagery) are to be constructed. Present and future pathways of cities (i.e. urbanization), in line with climate change pathways, will then be inputted to global and regional climate models to elucidate the aforesaid interactions and its implications to society.

| 研究実績の概要 |
We have successfully published our work on simulating the present and future climate of 43 largest megacities on an international journal. Furthermore, two domestic papers were also published in the prestigious Japan Society of Civil Engineers journal. The first domestic paper focuses on a more recent climate-change scenario (CMIP6). The second paper is a deep-learning-based land cover generator from satellite images needed for the urban parameterization. We have presented 4 research works in the 11th International Conference on Urban Climate. Lastly, we are considering air-conditioning as an adaptive measure, coupling air quality.

理由
Although it seems that the project is progressing smoothly after successfully presenting our findings on modelling of both urbanization and climate-change effects in publications and international conferences, we have not finalized the model for the updated global urban morphological datasets needed for the project. We have also added another general circulation model (GCM) for investigation because of the lack of manpower/support for the original model. The GCM (NICAM model) is based in Japan. This shift strengthened collaboration and speed up our work. We are also currently experiencing slight delay due to the upgrade of Tokyo Tech's Supercomputer. However, thanks to the upgrade, we expect faster simulation times and, hence, lower simulation costs.

| 今後の研究の推進方策 |
This year, our model will be publicly available and merged with the official Weather Research & Forecasting model. A paper on our findings on the global climate model will be submitted to a prestigious applied meteorology journal. The results will be presented in the upcoming Japan Geophysical Union in May and the American Geophysical Union in December. Domestic papers are also being drafted together with the students that include improved models for the urban parameters (i.e. roughness parameters and anthropogenic heat) that is due on May. With the help of another collaboration with University of Tokyo and Waseda University, we are investigating the potential of air-conditioners as an adaptation strategy based on the current GRUCCAM project.
