The Japanese 55-year Reanalysis (JRA-55)

DIAS (Data Integration and Analysis System)
204:JRA55
Reanalysis of long-term records of past observations with a state-of-the-art numerical analysis and weather prediction (NWP) system aims at producing a high quality, honogeneous data set for climate variables such as temperature and precipitation.
The Japan Meteorological Agency has conducted the second reanalysis project named the Japanese 55-year Reanalysis (JRA-55) using a more sophisticated NWP system, which is based on the operational system as of December 2009, and newly prepared past observations. The reanalysis period has been extended covering the period from 1958 to 2012. JRA-55 is a data set that aims at reproducing the climate change over the past half century more accurately.

In the report released on 2 October 2018, JMA announced that a part of the Japanese 55-year Reanalysis (JRA-55) product was missing, of which values were set to zero.
Those missing data has been replaced with corrected data. (2018-10-15)
It was recently found that a part of the Japanese 55-year Reanalysis
(JRA-55) product was missing, of which values were set to zero. Those
missing data are as follows. Product : fcst_surf125 (1.25-degree two-dimensional instantaneous diagnostic fields)
Period : from 4 June 2018 onward
Parameters : pressure reduced to MSL, total cloud cover, high cloud cover, medium cloud cover, and low cloud cover
The above mentioned product will be replaced with corrected data shortly,
which will be announced separately on the JRA-55 website. In the meantime,
users are advised to refrain from using those data. (2018-10-02)
