The researcher Xie Aihong etc. of Cold and Arid Regions Environmental and Engineering Research Institute recently undertaked  the following  experiment: the daily mean temperatures of National Centers for Environmental Prediction/National Center for Atmospheric Research (hereafter, NCEP/NCAR) reanalysis were compared with those independently observed by automatic meteorological stations (AMS) from Zhongshan Station, LGB69, Eagle and Dome A in eastern Antarctica from 2005 to 2006. It is found that the correlation coefficients were high, 0.624, 0.648, 0.744 and 0.705 (p＜0.001, n≥365) between the NCEP/NCAR reanalysis and the observations from Zhongshan Station, LGB69, Eagle and Dome A, respectively, which indicates that the NCEP/NCAR reanalysis is able to capture the annual and seasonal temperature change in the region. Compared with the observed temperatures at the above four stations, the NCEP/NCAR reanalysis has the characteristics of warm bias, decreasing annual temperature range and standard deviation, with an applicability better in spring and summer and worse in autumn and winter. Furthermore, there is a tendency that the error increases from the edge to the interior along the Route from Zhongshan Station to Dome A.
