Error components in rainfall retrieval from collocated commercial microwave links
Original language description
Commercial microwave links (CMLs) operating in telecommunication networks can serve as rainfall sensors. However, the diversity of such opportunistic sensors and their errors are difficult to handle. This analysis empirically evaluates errors of CML observations in a real network without reference to rainfall measurements. Independent collocated CMLs at twelve sites within a real telecommunication network in Prague enable us to assess the effect of hardware homogeneity and measurement consistency. The evaluation considers 33 rainfall events in the non-winter periods of the years 2014 to 2016, monitored at 1-min temporal resolution with signal uantization of 0.3 dB. The study evaluates eight sites of identical frequency band CMLs and six sites of different frequency band CMLs. Discrepancies between collocated CMLs of the same frequency are only due to hardware characteristics and enable us to evaluate the hardware homogeneity, whereas the discrepancies of CML pairs of different frequencies are due to hardware inhomogeneity and a different interaction of microwaves to the propagation medium.
