The prediction of cloud attenuation relying on the concept of reducing liquid water content to a fixed temperature ( w R ) is investigated. Based on an extensive dataset of radiosonde observations collected in Europe, the focus is on the quantification of the prediction error due to the approximation introduced with w R . The obtained cloud attenuation results indicate that the approximation error δ is markedly sensitive to the reduction temperature T R and that, specifically, T R = − 5°C turns out to minimise δ in European sites, whatever the frequency of interest in the 20–100 GHz range.
