arXiv:2607.01621v1 Announce Type: new Abstract: Fine-scale rainfall reconstruction is critical for urban flood modeling, but real rainfall sensing systems observe the field through incompatible spatial supports: gauges measure points, microwave links measure paths, and radar/satellite products measure gridded areas. These differences in measurement support impose geometrically distinct constraints on the rainfall field, yet existing heterogeneous graph approaches reconcile such sources in feature space, giving each its own embedding while discarding the geometry of its support. We propose a ge
The ongoing climate crisis and increased frequency of extreme weather events are accelerating the development of more accurate hydro-meteorological forecasting and monitoring technologies.
Improved fine-scale rainfall reconstruction is crucial for urban planning, disaster preparedness, and managing critical infrastructure, especially in areas prone to flash floods.
This research introduces a novel method that could significantly enhance the accuracy of rainfall predictions by integrating diverse sensor data more effectively, moving beyond current heterogeneous graph approaches.

More precise flood warnings and urban water management decisions become possible due to better rainfall data.
This could lead to reduced infrastructure damage and loss of life from metropolitan flooding events.
The methodology could be extended to other environmental sensing challenges, enhancing climate resilience across various sectors.
