Abstract: The present invention relates to an apparatus for calibrating temperature and humidity of a radio-sonde to be adapted to the upper air environment using an upper air simulation chamber including: an isotemperature-isohumidity unit calibrating temperature and humidity measured via the radio-sonde; a sunlight generation unit coupled to the isotemperature-isohumidity unit and generating sunlight to be irradiated to the isotemperature-isohumidity unit; an air supply unit coupled to the isotemperature-isohumidity unit and controlling the pressure and temperature of atmospheric air, allowing supplying air to the isotemperature-isohumidity unit; a sonic nozzle coupled to the isotemperature-isohumidity unit and creating an air flow set at below a set pressure; and a vacuum pump coupled to the isotemperature-isohumidity unit and discharging air which penetrates the isotemperature-isohumidity unit.
