To obtain high-accuracy post and real-time precipitable water vapor (PWV) with simple process when the measured meteorological parameters are unavailable, a grid direct conversion model of zenith tropospheric delay (ZTD) and PWV in tropical regions (named CZP) is proposed with the consideration of the characteristics of spatiotemporal changes based on ERA5 reanalysis data from 2016 to 2019. The results show that the CZP model has good performance at each grid points compared with ERA5 PWV.The comparison results with the GNSS PWV of 61 IGS stations in tropical regions show that the mean bias and root mean square (RMS) of CZP GNSS PWW are no more than 1.1 mm and 1.4 mm, respectively.
