FIELD: meteorology and can be used at creation of radiosondes measuring the weather quantity profile in the atmosphere. SUBSTANCE: aerological radiosonde uses measuring circuit 1 comprising weather quantity resistance transducer 2, standard resistors 3 through 5, two-position selector switch 6 and operational amplifier 7. The radiosonde uses also summing amplifier 8 based on operational amplifier 12 and resistors 9 through 11, time interval control channel unit 13, resistive adder 14, integrator 15, comparator 16, logic gates 17, 18 and radio transmitter 19. EFFECT: improved design. 2 dwg, 1 tbl
