| Research Abstract |
This research aims at collecting and data-basing old meteorological instrumental data in early 19th century during which no official instrumental data were available in Japan, and the purpose of this research is to clarify the climatic variations in the final stage of Little Ice Age based on our database. Most of the previous studies which discuss the recent climatic variations use official meteorological records by Japan Meteorological Agency, which could get back to 1880's at the earliest.
However, in global scale, there have been many studies which pointed out the rapid warming occurred at around 1850's and 1860's based on the instrumental data in Europe and North America. In our research project, we also found evidences for cooling in the 1830's and warming in the 1850's. These results indicate good agreement with those previous studies in European countries.
