Statistical results on the variability of the 0°C isotherm in all conditions and in rainy conditions are presented in this paper for ten years of radiosonde data. Concurrent with these data, nine years of rainfall measurements performed with a vertical Doppler radar (MRR-2) have allowed comparing the height of the 0°C isotherm with the height of the bottom of the bright band considering simultaneous events. The variability of both heights and of their difference has been investigated as well.enRadiosondeMeteorologyEnvironmental scienceAttenuationRadarDoppler radarRemote sensingAtmospheric sciencesClimatologyarticle
