JMA JRA-55 Reanalysis Data

December 17, 2014

The Japanese Meteorological Agency’s (JMA) Japanese 55-year Reanalysis project (JRA-25) is a reanalysis using the JMA numerical assimilation and forecast system. It covers the period from 1958 to 2013, starting when regular global radiosonde observations first became available. CDS has published the JRA-55 data in the ESGF ana4MIPs project for the purpose of comparing Reanalysis data to other Reanalyses, Observational data, and the IPCC AR5 Climate Model data.
