Short summary
We propose a new GPS tomographic parameterization approach based on inverse distance weighted (IDW) interpolation. This approach can reconstruct a humidity field. In the future, the fusion of GNSS and external measurements from other sensors in the GPS tomography system will be a potential means to enhance the stability and reliability of water vapor tomography and to decrease tomography intervals.
