Retrieving Precipitable Water Vapor Data Using GPS Zenith …

The number of geodetic GNSS stations set up in China has substantially increased over the last few decades. However, GPS PWV derivation requires surface pressure to calculate the precise zenith hydrostatic delay and weighted mean temperature to map the zenith wet delay to precipitable water vapor.

A deep learning-based model for tropospheric wet delay …

Existing machine learning zenith wet delay (ZWD) models have limitations in their feature extraction capabilities. To address these limitations, we propose a ZWD (CNN_ZWD) model which is built upon observation data collected from 88 radiosonde (RS) stations in China from 2015 to 2017, employing the one-dimensional convolutional …

New Models of Zenith Tropospheric Delay for Chinese …

Accurate models of zenith tropospheric delay (ZTD) is crucial in meteorology as well as in navigation and positioning. In this study, we employ Convolutional Neural Network (CNN) and Random Forest (RF) models to establish six direct or compensation models for estimating ZTD in Chinese mainland and surrounding areas. The modeling process …
