中文摘要：
本文通过分析中国东部6个观测站1958—1960年连续3年的地表热量平衡观测资料与相同时段的NCEP／NCAR再分析地表热量平衡资料在逐日、候、旬、月、季节、年等不同时间尺度上的差异，检验了20世纪60年代以前NCEP／NCAR再分析地表热量平衡资料在我国东部地区的可信度，结果表明：各站的NCEP／NCAR再分析地表热量平衡资料基本上能够较好地反映实际地表热量平衡通量的季节变化特征．随着时间尺度从日增大到年，NCEP／NCAR再分析资料与观测资料的误差逐渐减小，再分析资料的可信度随时间尺度的增大而逐渐提高．低纬地区的NCEP／NCAR再分析地表热量平衡资料与观测资料之间的误差较小，再分析资料的可信度较高，对于同一测站而言，再分析的辐射平衡和潜热通量资料比感热通量资料的可信度大，精度较高．与冬季相比，夏季再分析地表热量平衡资料更接近观测．在目前我国地表热量平衡观测资料相当缺乏的情况下，NCEP／NCAR再分析地表热量平衡资料不失为一种较好的用于研究气候变化的补充代用资料．
英文摘要：
We analyzed the relative errors of surface sensible heat flux, latent heat flux and radiative balance data between NCEP/NCAR reanalysis and observations at 6 stations in eastern China during 1958--1960 on different timescales and validated the credibility of the NCEP/NCAR reanalysis surface energy balance data in this paper. The results show that the seasonal variations of the NCEP/NCAR reanalysis data are in good agreement with the observations, and the errors reduce with the increasing timescale from daily to annual, and the NCEP/NCAR reanalysis surface energy balance data become more reliable with the timescale increas~ There are less errors in low latitudes than those in high latitudes and the reliability of the reanalysis data is higher in low latitudes. At the same station, the radiative balance is the most reliable among the three components of the surface energy budget. The surface energy balance reanalysis data are closer to the observations in summer than in winter. Therefore, the NCEP/NCAR reanalysis surface energy budget data are important complementary resources for the climate change studies.
