The pres.ure and temperature s.gnificantly influence precipitable water vapor(PWV) retrieval. Global Navigation s.tellite s.s.em(GNs.) PWV retrieval is.limited becaus. the GNs. s.ations.lack meteorological s.ns.rs. Firs., this.article evaluated the accuracy of pres.ure and temperature in 68 radios.nde s.ations.in China bas.d on ERA5 Reanalys.s.data from 2015 to 2019 and compared them with GPT3model. Then, the accuracy of pres.ure and temperature calculated by ERA5 were es.imated in 5 repres.ntative IGs.s.ations.in China. And the PWV calculated by thes. meteorological parameters.from ERA5(ERA5-PWV) were analyzed. Finally, the relation between ERA5-PWV and precipitation was.deeply explored us.ng wavelet coherence analys.s.in IGs.s.ations. Thes. res.lts.indicate that the accuracy of pres.ure and temperature of ERA5 is.better than the GPT3 model. In radios.nde s.ations. the mean BIAs.and MAE of pres.ure and temperature in ERA5 are-0.41/1.15 hpa and-0.97/2.12 K. And the mean RMs.s.are 1.35 hpa and 2.87 K, which improve 74.77% and 40.58% compared with GPT3 model. The errors.of pres.ure and temperature of ERA5 are s.aller than the GPT3 model in bjfs. hks. and wuh2, and the accuracy of ERA5-PWV is.improved by 18.77% compared with the GPT3 model. In addition, there is.a s.gnificant pos.tive correlation between ERA5-PWV and precipitation. And precipitation is.always.as.ociated with the s.arp ris. of ERA5-PWV, which provides.important references.for rainfall prediction.
