Comparisons of precipitable water vapor and zenith total delay derived from GNSS measurements, radiosondes, and ERA5 reanalysis data in the contiguous United States
Puntos clave
Precipitable water vapor measurements show significant variation across different data sources.
Zenith total delay averaged 20 millimeters across analyzed regions, indicating regional differences.
Assessment using GNSS measurements, radiosondes, and ERA5 reanalysis data provides a comprehensive evaluation.
Findings suggest that integrating multiple data sources may enhance weather modeling accuracy.
