[Abstract]

　This research aims the establishment of flux measurement technique of global warming gases, such as, carbon dioxide, by way of an aircraft. For this purpose, atmospheric air is sampled and temperature, humidity and air velocity data are measured in conjunction with flight maneuver data. Correlating measured gas concentration and vertical air velocity, the flux of the gas can be obtained. In 1996, the ultrasonic anemometer was calibrated in the wind tunnel and in-flight experiments of the probe mounted on the aircraft were perfomed.
