In this letter, we show how an operational microwave link network can be used to reconstruct 2-D fields of accumulated rainfall over a limited area at ground level. To this purpose, we use a tomographic technique that exploits the relation between rainfall rate and the attenuation experienced by the microwave links of the network. The links located in Italy operate at K-band and are managed by an Internet service provider. The results are validated by comparing the reconstructed rainfall maps with those derived from a network of conventional rain gauges. Finally, we assess by simulation the impact of the network's density and topology on the accuracy of the reconstruction algorithm.

Abstract
In this letter, we show how an operational microwave link network can be used to reconstruct 2-D fields of accumulated rainfall over a limited area at ground level. To this purpose, we use a tomographic technique that exploits the relation between rainfall rate and the attenuation experienced by the microwave links of the network. The links located in Italy operate at K-band and are managed by an Internet service provider. The results are validated by comparing the reconstructed rainfall maps with those derived from a network of conventional rain gauges. Finally, we assess by simulation the impact of the network's density and topology on the accuracy of the reconstruction algorithm.| File | Dimensione | Formato | |
