JRA-55 assimilating Conventional observations only (JRA-55C)

Abstract:
As a subset of the Japanese 55-year Reanalysis (JRA-55) project, the Meteorological Research Institute of the Japan Meteorological Agency is conducting a global atmospheric reanalysis that assimilates only conventional surface and upper air observations, with no use of satellite observations, using the same data assimilation system as the JRA-55. The project, named the JRA-55 Conventional (JRA-55C), aims to produce a more homogeneous dataset over a long period, unaffected by changes in historical satellite observing systems. The dataset is intended to be suitable for studies of climate change or multi-decadal variability. The reanalysis period of the JRA-55C is from 1958 to 2012. Note, however, that the data for the period from 1958 to Oct 1972 are exactly the same of JRA-55. We recommend to use together with the JRA-55 data in the period. The dataset is provided in GRIB.
