Japanese 25-year ReAnalysis (JRA-25) and JMA Climate Data Assimilation System (JCDAS)

Last updated: February 2014


The Japan Meteorological Agency (JMA) and the Central Research Institute of Electric Power Industry (CRIEPI) conducted the Japanese 25-year Reanalysis (JRA-25) project to produce a climate dataset for the period from 1979 to 2004.

JMA also continued the production on a near real-time basis using the same data assimilation system as used for JRA-25, called the JMA Climate Data Assimilation System (JCDAS), to monitor the present state of climate.


The provision of these data was terminated in February 2014.
