In this paper, radiosonde observation data from Changsha, Huaihua, Chenzhou in Hunan province are used to establish aTmlocalizationmodelbasedonnumericalintegration and the least squares principle. The results show that the system deviation of Bevis model is 2.51 K compared with the Tm from radiosonde as a reference value. The inner precision of the Hunan Tm localization model is 1.41 K, the mean bias is 1.60 K, and the correlation coefficient is 0.942 5. Compared to the radiosonde PWV, the average bias and RMS of GPS PWV using localization Tm model are 0.52 mm and 245 mm. Experimental analyses demonstrate that the precision of the Hunan localization Tm model is better than the Bevis model. It can be applied to research on and applications of GPS meteorology in Hunan region."/>
