Short summary
In this paper we have assessed the positive difference observed between radio-occultation-retrieved refractivity and that of weather analyses and reanalyses when heavy precipitation is present. The impact of the precipitation media on the refractivity observable has been evaluated, showing that precipitation itself cannot explain the magnitude of the observed difference. Instead, the difference is shown to be linked to high specific-humidity conditions, which in turn are linked to rain.
