%X The Reanalysis datasets are widely used in climate change research,but the reliability of the reanalysis datasets at different time-spatial scale can also impact the results of the study.An preliminary intercomparison of monthly mean surface 2 m temperature and precipitation are made between the ERA-40,NCEP-2 reanalysis and the observations to validate the reliability of the reanalysis over China.The results show that the temporal and spatial distribution of temperature and precipitation for the ERA-40 and NCEP-2 are similar with the observed counterparts,although some differences can be aware of in the west region of China,especially in Tibet Platean.In terms of reliability,the temperature is higher than the precipitation,the East than the West,and the ERA-40 than the NCEP-2.
