| 講演名 | 2007-04-16 10:45 A Comparison of Atmospheric Temperature and Moisture Profiles Derived from GPS Radio Occultation and Radiosonde in Australia ○Kefei Zhang（RMIT Univ.）・Bertukan Biadeglgne（Australian Bureau of Meteorology）・Falin Wu（RMIT Univ.）・Yuriy Kuleshov・Anthony Rea・Graham de Hodet（Australian Bureau of Meteorology）・Erjiang Fu（RMIT Univ.）  SANE2007-2 |

| 抄録 | （和） | The GPS radio occultation (RO) sounding technique that uses signals transmitted by the GPS satellites has evolved as an important global atmospheric observing technology. This research compares atmospheric profiles from GPS RO with radiosonde-retrieved profiles. Temperature and water vapor profiles from CHAMP satellite mission are compared with those calculated from radiosonde soundings over Western Australia. Results show that the differences between atmospheric temperatures derived from the low earth orbiting satellite data and measured by radiosondes are less than 1 K for altitudes below 14 km and less than 3 K in the vicinity of the tropopause. For water vapor profiles, the difference is less than -0.4 hPa in the lower troposphere and less than +0.4 hPa in the upper troposphere. |
