[a. G. radiosonde (P. Moltchanoff 1931, in Beiträge z. Geophysik XXXIV. 36), f. radio- radio- + sonde probe, sounding-line.]
A small package of meteorological instruments which is carried through the atmosphere by balloon or other means and automatically transmits measurements of conditions at various heights by radio. Freq. attrib. So radiosondage |-ˈsɒndɪdʒ|, sounding of the atmosphere by radiosonde.
