The package was attached to a balloon filled with hydrogen or helium and released to measure an atmospheric profile on the ascent and, if fitted with a parachute, the descent. The radio retransmitted LORAN-C signals allowing the balloon to be tracked giving measurements of winds."@en ; skos:notation "SDN:L22::TOOL0619" ; skos:note "accepted"@en ; skos:prefLabel "VIZ 1223 Radiosonde"@en .
