Short summary

A time-varying global gridded T_s–T_m model with 0.75 × 0.75 degree spatial resolution is developed in our study to precisely estimate water-vapor-weighted mean temperature T_m from surface air temperature T_s. Using multiple statistical tests, we assessed the T_m of our model and its impact on the GPS–PWV retrievals. Comparisons with other models demonstrate that our model has prominent advantages. Matlab codes and arrays used to realize our model are provided in the supplement of this study.
