Figures
Figure 2. Boxplots describing the duration of precipitation events per month in 2015 with orange as median and green as mean duration. The box edges represent the first and third quartile, and the whiskers are the 10th and 90th percentile. The values are computed using disdrometers installed along the 2.2 km microwave link path. In these statistics, events shorter than 5 minutes are excluded. 
Figure 4. Comparison of received (solid) and baseline (dashed) power levels (a-d, i-l, q-t) and retrieved rain rates (e-h, m-p, u-x) during a low-intensity precipitation event on 24 November 2015 obtained with the Nokia (a-h), RAL 38 GHz (i-p) and RAL 26 GHz (q-x) microwave links for all sampled variables and the 1-second, 5-minute and 60-minute time intervals. Grey areas indicate dry periods based on disdrometer data. 
Figure 7. Statistical metrics as function of time interval for for a theoretical low intensity and high intensity rain event (Fig. 3) for all sampling methods (line style) for 38 GHz and 26 GHz horizontally polarized noiseless devices (line color). 
Figure 12. Comparison of rainfall intensities derived for min-max sampling at a 5-minute time interval (using an optimized weight) versus time-averaged rainfall intensities computed with the 20 Hz data for the RAL 26 GHz microwave link. The red dashed line is the 1:1 line and the black line represents the linear regression line through the origin of which the slope is reported in the statistics box. 
Figure 6. Statistical metrics as function of time interval for three theoretical rain events (Fig. 3) for all sampling methods (line style) and added noise levels that resemble the three devices (line color). 
Figure 1. Map of Wageningen with the path of the links in red. The receiving antennas are at the end labelled “Forum”; the transmitting antennas are positioned at the end labelled “Biotechnion”. The yellow stars indicate the position of disdrometers along the path. At each disdrometer location, one disdrometer is located, except at "Forum", which has two disdrometers placed next to eachother. Figure redrawn after van Leth et al. (2018a) (with © Google Maps).

TL;DR: In this paper, the empirical relation A = aR^{b} between the specific attenuation A and the rain rate R is used in the calculation of rain attenuation statistics.

Path- and Area-Integrated Rainfall Measurement by Microwave Attenuation in the 1–3 cm Band
David Atlas,Carlton W. Ulbrich +1 more
TL;DR: In this article, a compromise between maximum path-averaged rainfall rate sensitivity and minimum sensing errors may be achieved by the use of one-way methods between the transmitter and the receiver, with a wavelength of 1.5 to 2.0 cm.

TL;DR: Here it is demonstrated how measurements of the received signal level, which are made in a cellular network, provide reliable measurements for surface rainfall.
Radar for hydrology: unfulfilled promise or unrecognized potential?
Alexis Berne,Witold F. Krajewski +1 more
TL;DR: In this article, a review of the use of weather radars in hydrology is presented, focusing on the opportunities and challenges of using weather radar in hydrological applications, such as flash floods, urban hydrology, rainfall spatial extremes.

Country-wide rainfall maps from cellular communication networks
TL;DR: In this paper, the authors proposed a real-time approach to retrieve the space-time dynamics of rainfall for an entire country (The Netherlands, ∼35,500 km2), based on an unprecedented number of links (∼2,400) and a rainfall retrieval algorithm that can be applied in real time.
