Wet Antenna Attenuation (WAA)

This module groups the methods related to wet antenna attenuation.

Constant wet antenna attenuation

The simplest wet antenna attenuation model involves subtracting a constant value from the measured attenuation. This method was originally proposed by Overeem et al. (2013), who obtained a value of 2.3 dB by calibrating the model using 12 days of data from the Netherlands. We use this value as a reasonable default; however, it should be calibrated for each specific region and deployment.
