摘要

The design of an instrument based on a solid state tungsten oxide sensor for making profile measurements of atmospheric ozone from balloon platforms is described.The sensor is operated at a constant temperature,typically 530 deg C.The importance of a detailed consideration of the electronic design is demonstrated,with particular reference to the circuit to control the sensor heater.Calibration methods which are straightforward to implement are illustrated,and the results of a test flight alongside an electrochemical ozonesonde are shown.Quantitative agreement within 25% for most of the profile demonstrates the potential of this type of sensor for ozone sounding.Future improvements from manufacture to analysis are expected to improve on this.
