Japanese 25-year ReAnalysis, Monthly Climatology, Surface

Japanese 25-year ReAnalysis (JRA-25) is produced by the Japan Meteorological Agency (JMA) in collaboration with Central Research Institute of Electric Power Industry (CRIEPI. The global model resolution is T106L40 (model top: 0.4hPa). Reanalysis period is from Jananuary 1979.
