In
the framework of a long-term joint co-operation between Japan and KNMI aimed at climate reconstruction
of Japan in its
pre-instrumental era, we now explored the availability of the mostly visual
weather data in the daily Diary of the Chief of the Dutch trading post on the
island Dejima near Nagasaki. A Pilot project extracted the Januaries of the
years 1700-1860; the Follow-up project extracted all months during the period
1817-1823, the term of office of the Chief Jan Cock Blomhoff. Together with the
subsequently extracted Von Siebold data 1825-1828 (a supplementary project),
the Cock Blomhoff series provides a detailed picture of the Kyushu
daily weather in the early 19th century. With this report all data are made
systematically accessible and available for further analysis.
The data files can be
accessed either directly by going to https://data.knmi.nl/datasets/decima/1?q=Japan,
or by first going to the KNMI database https://data.knmi.nl/datasets,
and then typing in the keyword field either ‘Japan’, or ‘Decima’.
