Japan Climate Data Project


Imaging and digitization of old paper-based instrumental meteorological records must be carried out before these records are lost to decay. This kind of activity called “DATA RESCUE” is now taking places at many institutions all over the world. In Japan, we also have been working on data rescue for Southeast and East Asian instrumental meteorological records taken before the funding of official meteorological observations.
After rescuing the data, it is also important to share the data, so this “Japan-Asia Climate Data Program” website is aiming at distributing the data. Besides the instrumental records, datasets of weather descriptions collected from Japanese historical documents are also included and made available to the public in this website.
Past climate reconstruction based on these kind of documentary sources is essential to not only understanding past climate variability but also projecting the future climate.
