| Research Abstract |
GPS radiosonde with radiation flux sensors was newly developed in order to elucidate radiative heat transfer mechanism in urban-earth subscale atmosphere. After characterization and calibration of the radiosonde were carried out in temperature-controlled room, balloon observation tests were conducted in urban area and vertical profiles of upward and downward infrared radiation heat flux were successfully obtained. The developed radiosonde is low cost as compared to the conventional observation device, hence, is suitable for long-term observation. Furthermore, inverse analysis method was also developed in order to evaluate radiative properties of the atmosphere from the observation data.
