The paper have built the local correction models for dry delay and atmospheric weighted temperature and have made a comparison between two models for calculating actual water vapor on the basis of actual upper - air detecting data . ah results show that the conclusion is satisfied 本研究利用实际探空资料建立了大气干延迟和大气加权平均温度的局地订正模型，并对实际水汽计算模型进行了比较，得到了满意的结果。
