Spatiotemporal Fusion of DEM-Corrected GNSS-PWV and Radar Reflectivity for Extreme Precipitation Nowcasting in Complex Terrain
Short-term extreme precipitation nowcasting remains challenging because convective rainfall evolves through coupled moisture, dynamical, and microphysical processes that are only partially observed by any single sensor. Radar composite reflectivity (CR) directly describes hydrometeor structures, whereas global navigati...
