Outline of Final Research Achievements

The aim of this study is to investigate the vertical structure of the thermal tides by analyzing radio occultation data of Venus Express. We used temperature profiles retrieved from radio occultation data obtained in 2006 to 2010 and tried to investigate the structure of the thermal tides in the equatorial region, where the thermal tides will have a large amplitude. As a result, we detected the thermal tides with zonal wavenumber-2, which propagate downward from the cloud layer. However, we did not investigate it at much lower altitude and specific localtime because the number of data is too small. In the future we are going to analyze the data obtained after 2011 and investigate it more precisely.
