The backhauling links of terrestrial wireless networks (Commercial Microwave Links, CMLs) and the downlink of satellite broadcasting/broadband services (Satellite Microwave Links, SML) operating in the Ku-band and above, say >10 GHz, proved effective opportunistic systems for rainfall sensing. CMLs and SMLs exhibit, indeed, features that make them suitable to complement conventional...
Rainfall has been monitored with microwave links opportunistically for nearly 20 years. So far, most studies have focused on retrieving rainfall rates using the mean received signal, based on the power-law relation between specific attenuation and rainfall rate. However, theories and measurements have indicated that the power spectral density (PSD) of received signal contains extra information...
On 29 October 2024 torrential rainfall exceeding locally 300 mm within less than 24 h, triggered devastating flash floods in the province of Valencia in Spain. Rainfall sums equivalent to more than half a year’s total precipitation occurred within just a few hours. In this region, more than 200 low-cost weather observation devices, referred to as personal weather stations (PWSs), are located....
Rainfall-runoff processes are highly dynamic in urban areas. For flood risk management an accurate estimation of spatial and temporal rainfall distribution are essential. In view of increasingly available data sources for rainfall observations we investigate the benefits that additional data sources can bring to the reconstruction of convective heavy rainfall. In this study we focus on the...
