SPWV-H: A Spatially-enhanced Vertical Adjustment Model for Global Precipitable Water Vapor

This dataset contains the coefficients and parameters for the Spatially-enhanced Vertical Adjustment Model for Precipitable Water Vapor (SPWV-H). The model is designed to improve the accuracy of vertical interpolation of Precipitable Water Vapor (PWV) across different altitudes and geographic regions. The dataset includes:<br>Model coefficients for three spatial resolutions: 1°x1° (SPWV-H1), 2°x2° (SPWV-H2), and 3°x3° (SPWV-H3)Piecewise function parameters for different latitude zones and atmospheric layersFourier series coefficients for temporal variationsMatlab code for implementing the SPWV-H modelSample ERA5 reanalysis data used for model development and validationRadiosonde and GNSS validation datasetsScripts for data processing and model implementationThis dataset enables researchers to apply the SPWV-H model for accurate vertical adjustment of PWV, facilitating multi-source PWV data fusion and expanding applications for surface-based GNSS PWV monitoring.
