| Summary: | <p>Precise continuous measurements of relative humidity (RH) vertical profiles in the troposphere have emerged as a considerable scientific issue. In recent years, a combination of diverse ground-based remote sensing devices has effectively facilitated RH vertical profiling. This work introduces a newly developed approach for obtaining continuous RH profiles by integrating data from a Raman lidar, a microwave radiometer (MWR), and satellite sources. RH profiles obtained using synergistic approaches are subsequently compared with radiosonde data throughout a 5-month observational study in China. Our suggested method for RH profiling demonstrates optimal concordance with the best correction coefficients <span class="inline-formula"><i>R</i></span> of 0.94 in Huhehaote (HHHT), 0.92 in Yibin (YB), and 0.93 in Qingyuan (QY). The mean value of RH decreased with height and presented seasonal characteristics in QY. Finally, the RH height–time evolution was used to distinguish hail and heavy precipitation. This study integrates satellite data into ground-based measurements to retrieve RH vertical profiles in China.</p> |
