Abstract : A method and apparatus to calibrate the thermistors of radiosondes are described. The method is based on cooling alcohol and toluene to -95 to -100C and a method for checking the readings of test thermometers at these temperatures against reference points. The method utilizes the familiar relationship between the sublimation point of dry ice and the external pressure.
