The L-band Secondary Windfinding Radar-Radiosonde Upper-Level Atmospheric Sounding System is the new generation upper-level atmospheric sounding system in China. Its capability, operating approach, and operational procedures differ from those of the 59-701 Sounding System. Some use skills and experiences in troubleshooting for the new generation upper-level atmospheric sounding system are introduced, including various abnormal phenomena in radar check, radiosonde basic measurement, battery immersion, instrument assemblage, instant measurement, data input, balloon launching, balloon position identification by the side-lobe echoes, balloon losing in sounding, and problems in balloon-launching software.
