Climate change greatly affects human society. Learning about past climate helps to predict future changes more accurately. Before modern instrumental measurements became available, old diaries provide valuable information about historical weather. Especially in Japan, there are over 50 diaries recording daily weather information at more than 18 locations during the mid-Edo period to the early Meiji period. These descriptive records are valuable; for example, cloud cover information converted from old diaries can be combined with the latest high-technology of numerical weather prediction. However, there are still some challenges to this fusion approach. This presentation will introduce some disadvantages in an existing method and explain how he/she will improve it. He/She will present whether this new method improves the reconstruction results. In general, this presentation will introduce the potential of diary-based information for weather reconstruction in Japan.
