Improved Gridded Precipitation Data Derived from Microwave Link Attenuation

The motivation for improving gridded precipitation data lies in weather now-casting and flood forecasting. Therefore, over the past decade, Commercial Microwave Link (CML) attenuation have been used to determine rain rates between microwave antennas, produce more accurate countrywide grids. CML networks offer a unique advantage measurements due their high density. However, these experience uncertainty from several sources as reported earlier research. This current work determines reliability of rainfall each link by comparing CML-derived adjusted radar at location, three months. Dynamic Time Warping (DTW) is applied pair CML/radar time-series two study areas, Israel Netherlands. Based on DTW amplitude temporal distance, unreliable links are identified flagged, interpolated derived country after filtering out those links. Correlations grids observations an independent set gauges, tested events both higher reliable subset than full set. For certain storm events, Kendall rank correlation almost double that complete set, demonstrating improved can be obtained removing
