An ERA5‐based model for estimating tropospheric delay and weighted mean temperature over China with improved spatiotemporal resolutions
Tropospheric delay is an important error source in Global Navigation Satellite System
(GNSS) positioning and can also be used in water vapor monitoring. Many models have
been built to correct tropospheric delays or to convert zenith wet delays to precipitable water
vapor. However, these models suffer from limited resolutions (spatial resolution lower than
1° and temporal resolution lower than 6 hr), which affects their performance. The release of
European Centre for Medium‐Range Weather Forecasts ReAnalysis 5 (ERA5) provides the …
